Installing Ruby 2.0.0 with RVM and Homebrew on Mac OS X 10.8 Mountain Lion

comment icon72 comment(s) |

This is a tutorial on how to install Ruby 2.0.0 on Mac OS X 10.8 Mountain Lion. 

1. Install Xcode and the Command Line Tools

If you don't have it installed I suggest you install Xcode from the Mac App Store and install the command line tools in Xcode Preferences -> Downloads.

Otherwise if you don't want to do that you can download the Xcode standalone command line tools for Mountain Lion at https://developer.apple.com/downloads/index.action (Note: You will have to login with your Apple Id.).

2. Install Homebrew

ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go)"

Now run:

brew doctor

If you get the error:

Error: No such file or directory - /usr/local/Cellar

Run the following:

sudo mkdir /usr/local/Cellar

and

sudo chown -R `whoami` /usr/local

3. Install RVM

curl -L get.rvm.io | bash

After this is complete execute the following in order to use RVM in your current shell:

source ~/.rvm/scripts/rvm

4. Add the following to your ~/.profile in order to source RVM everytime you run Terminal.app:

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"

5. Check RVM Requirements

rvm requirements

Note the "Missing required packages: ..." statement. 

If you have any missing required packages you will need to install them before continuing by running brew install <missing package name>.

For example, here is the output I had:

$ rvm requirements
Installing requirements for osx/10.8/x86_64, might require sudo password
Skipping `brew update` make sure your formulas are up to date.Missing required packages: autoconf, automake, libtool, pkg-config, apple-gcc42, libyaml, readline, libxml2, libxslt, libksba, openssl, sqlite.
/Users/christopherkaukis/.rvm/scripts/functions/requirements/osx_brew: line 61:
/usr/local/Cellar/openssl/1.0.1e/bin/openssl: No such file or directory
/Users/christopherkaukis/.rvm/scripts/functions/requirements/osx_brew: line 63: /cert.pem: Permission denied
/Users/christopherkaukis/.rvm/scripts/functions/requirements/osx_brew: line 64: /cert.pem: Permission denied
/Users/christopherkaukis/.rvm/scripts/functions/requirements/osx_brew: line 65: /usr/local/Cellar/openssl/1.0.1e/bin/c_rehash: No such file or directory

If you need to install apple-gcc42 and get an error:

Error: No available formula for apple-gcc42

Run the following:

brew tap homebrew/dupes

If you get an error after running this:

Error: Already tapped!

Run the following instead to repair:

brew tap --repair homebrew/dupes

Now you can continue and install apple-gcc42:

From the "Missing required packages: ..." line above, for example I can now execute the following:

brew install autoconf automake libtool pkg-config apple-gcc42 libyaml readline libxml2 libxslt libksba openssl sqlite

 

6. Run brew doctor again to make sure everything checks out

Execute the following:

brew doctor

If you get an error or warning about your PATH. Such as:

Warning: /usr/bin occurs before /usr/local/bin

Open your ~/.profile and add the following line to the top (or bottom, it shouldn't matter):

export PATH=/usr/local/bin:$PATH

Run brew doctor to check all is swell before continuing.

7. It's now time to install Ruby 2.0.0:

First run the following commands:

rvm get head

followed by:

rvm requirements

If you don't get any errors you can finally install Ruby 2.0.0:

rvm install 2.0.0

To set as your current version of Ruby run the following command:

rvm use 2.0.0

To make it the default Ruby:

rvm default 2.0.0

or 

rvm use 2.0.0 --default

Now every time you open Terminal.app Ruby 2.0.0 will be default. You can always check which version of Ruby you have using the following command:

ruby -v

and where it's located executing the command:

which ruby

I hope this tutorial was useful. You are now setup to run Ruby 2.0.0 on Mac OS X 10.8 Mountain Lion. Shall you have any issues post a comment below and I'll try and help you out.

Just another programmer

One additional issue

First of all thanks for the excellent guide!

On step #7, after typing "rvm requirements" I still got the same error message with the cert.pem that was supposed to be handled earlier (on step #5).

The way I worked around it was:

rvm --autolibs=4 requirements ruby-2.0.0

and then again:

rvm requirements
now it returned "clean" and I could continue with:
rvm install 2.0.0

On running 'rvm requirements'

On running 'rvm requirements' I am having hard time installing apple-gcc42. I am getting below error.

Can anyone please suggest any steps to resolve this

April 10, 2013

ckaukis

Looks like you need to update

Looks like you need to update Xcode and the command line tools. Homebrew doesn't like your current version of Xcode. The only way around installing a new version of Xcode is possibly trying to install an older version of apple-gcc package, but I can't guarantee that will work. You can view all versions available in Homebrew with the following command:

brew versions apple-gcc42

or

brew search apple-gcc42

This will tell you where the older packages are located and you will have to "tap" or activate that repository.

So, for example, if it came back and said something like homebrew/versions/apple-gccXYZ you will have to run:

brew tap homebrew/versions

Then run:

brew install apple-gccXYZ

Again, I can't gurantee this will work as I have not tried it, but these are your two options I see. They both may work, or only one may work. Let me know if it helps.

After running the first line, it errors and tells me to remove my existing homebrew install. I do so, but get an error related to a font directory. I continued nonetheless and began the homebrew install steps, and get a few screens of errors, all like the first one below. After a few screens of that error (different files), I get the last two errors.

brew doctor Warning Unbrewed static libraries

Hi Christopher,

Just ran brew doctor after installing Homebrew and got the following warning:

Warning: Unbrewed static libraries were found in /usr/local/lib.
If you didn't put them there on purpose they could cause problems when
building Homebrew formulae, and may need to be deleted.

Unexpected static libraries:
/usr/local/lib/libhistory.a
/usr/local/lib/libreadline.a

Question: How do I delete Unexpected static libraries (I previously followed a very old tutorial with older version of Ruby - never used those libraries, or Ruby)? Or do I need to delete the existing static libraries?

I'm new at all of this (Mac Terminal, Ruby) and don't want to mess it up, so will not proceed until I hear from someone, how to proceed.

Thanks,
Heidi

Heidi, I have never seen

Heidi,

I have never seen these errors before. I did a little google searching for you and found this which I think might help:

http://stackoverflow.com/questions/10580813/how-do-i-fix-brew-doctor-errors

If it was me, I would probably try removing or deleting it. I like to live on the wild side. ;)

Sorry I don't have an absolute answer for this.

If you want to delete them, use the "rm" command. You may have to use sudo and type your password if you don't have permissions to do so. Since the files in question are in /usr/local I don't think you have worry about harming much unless you installed other software relying on libraries in that directory (usually user installed library and applications).

Does that make sense? Hope it helps some.

how to remove?

Hi Chris,

I agree with removing the files, but I don't know how to use the "rm" command. Would you please be more specific? I am very grateful for all your help.

Thanks,
Heidi

June 7, 2013

Heidi W.

delete/remove

Hi Chris,

Not sure what difference is between delete and remove, but I would prefer to delete, as opposed to moving the files elsewhere, because I have no clue what to do with them.

Is this correct - with safeguard of confirming removal/deletion?

rm -i libhistory.a

and then for 2nd file:

rm -i libreadline.a

Thanks,
Heidi

Hi Chris,

You'll be happy to know that I did it --- thanks to you EXCELLENT instructions.
Install of ruby-2.0.0-p195 - #complete

Do you have any instructions for installing current version of Rails, and a local server - which db is the easiest to use for beginners?

What else do I need to install to get going (I just signed up for a beginning class with O'Reilly School of Technology) but they are using an older version of Ruby that will not work on my Mac (OS X 10.8.4) so I need to get everything set up on my Mac and would like to use TextMate as the text editor. All of this information, for us beginners using Mac OS X 10.8, is difficult to find in one place on the web, but so far, YOUR information has been the MOST RELIABLE!

Thank you!

Hi Chris,

How do I find that using the terminal?

Heidi, I don't know of any puts command. That's a ruby command.

Re-install Ruby?

Hi Chris,

Somehow, the Ruby 'puts' command was removed during Rails 3.2.13 install because the line, '-bash: puts: command not found' was not showing in my Terminal before Rails install, and I did nothing in between brew Ruby install and rails install.

If I were to re-install Ruby 2.0.0p195 using Homebrew, would I need to first 'delete' Ruby, or would the new install rewrite over the current install without deleting it first?

Thanks,
Heidi

June 21, 2013

ckaukis

Heidi, sorry for the late

Heidi, sorry for the late reply. Didn't see this comment.

If you can, I would start from scratch. Are you able to figure out what and how to delete everything?

You can remove Homebrew using this shell script: https://gist.github.com/mxcl/1173223

Save it on your computer and run it in Terminal.app: shell name_of_script

The name you save it as doesn't matter.

You can remove RVM a couple ways:

rvm implode

or

rm -rf ~/.rvm

and delete out the lines in your .bash_profile, .profile files referencing anything RVM.

Then, try it from the start.

Let me know if that helps at all. You can email me too (firstname at this domain dot com).

Thank you!

Great tutorial! And it works (which is even better – and rarer).
One possible correction: I don't know if others had this issue, but for the very first command I needed to use:
ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go/install)"
instead of:
ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go)"
as you have listed. I pulled this from the Homebrew page. Maybe the "install" part is supposed to be obvious; I didn't know to put it there. (I'm very new to CL)
Anyway, a small matter – and something I mention just so that others don't get hung up on it and miss this otherwise excellent guide.
Thanks!

Re: ruby version configuration help needed

its a great article.

I had lots of missing dependencies but with the above help I installed 3 ruby version. As default it installed latest one, then I installed the version I need to work with, and the one which was coming with the mac default installation in my system.

So I tried many ways to set a particular version as my default permanent version to be used as using .bash_profile with entries -s "$HOME/.rvm/scripts/rvm" && source "$HOME/.rvm/scripts/rvm". but could not help me.

I am new to this so if you could help me it would be really appreciable and great !

Thanks in advance !

got a warning message about link gcc46 as ran brew doctor

After I completed installing rvm, I ran rvm requirements. Systems prompted Nings-MacBook-Air:~ NingJoeChang$ rvm requirements
Checking requirements for osx.
Certificates in '/usr/local/etc/openssl/cert.pem' are already up to date.
Requirements installation successful.

However, when I ran "brew doctor" again it gave me a warning, Nings-MacBook-Air:~ NingJoeChang$ brew doctor

Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry and just ignore them. Thanks!

Warning: You have unlinked kegs in your Cellar
Leaving kegs unlinked can lead to build-trouble and cause brews that depend on
those kegs to fail to run properly once built. Run brew link on these:
gcc46

Is it matter? Would you please kindly let me know how to fix it if it is necessary.,
Big thanks.
