Can't install Ruby Enterprise Edition with RVM on OSX Lion - ruby

Question

Here is what I have done so far.
Clean install of OS X Lion
Downloaded and installed latest version of Xcode from the App Store.
Installed Git
Installed Homebrew
Installed RVM
I am now trying to install Ruby Enterprise Edition for a project with rvm install ree and receive the following error:
$ rvm install ree
ree-1.8.7-2011.03 - #installing
ERROR: Error running './installer -a /Users/FaraazKhan/.rvm/rubies/ree-1.8.7-2011.03
--no-tcmalloc --dont-install-useful-gems ', please read
/Users/FaraazKhan/.rvm/log/ree-1.8.7-2011.03/install.log
ERROR: There has been an error while trying to run the ree installer. Halting
the installation.
I have already tried CC=/usr/bin/gcc-4.2 rvm install ree and with the same result.

Answer 1

I was able to duplicate your error, just now. This solved it for me:
$ rvm remove ree
$ export CC=/usr/bin/gcc-4.2
$ rvm install --force ree

Answer 2

Using MacPorts you can install Ruby Enterprise Edition, as well as Ruby 1.9.2 for the local user in OS X Lion while having Xcode 4.2 installed by using "Apple's version of gcc 4.2."
Prerequisites:
OS X Lion (tested in 10.7.2)
Xcode 4.2
rvm 1.9.1
MacPorts 2.0.3
Execute the following commands:
$ sudo port install apple-gcc42
$ export CC=/opt/local/bin/gcc-apple-42
then
$ rvm install ree
$ rvm use ree
or
$ rvm install 1.9.2
$ rvm use 1.9.2
optionally
$ rvm use ree --default
or
$ rvm use 1.9.2 --default
I hope this helps.

No need to install MacPorts or downgrade to 4.1 to get GCC, I used the installer package at https://github.com/kennethreitz/osx-gcc-installer with xCode 4.2 already installed, and had no problem installing 1.9.2-head and 1.9.2-p290.

Answer 4

I did something similar to what jbg advised. Only I didn't use MacPorts. I just used the latest GCC package for Lion here.
This was after spending about a day and a half trying all of the other suggestions, downgrading to Xcode 4.1, etc. to no avail.
By the way, the direct link to Xcode 4.1 at Apple's site gave me an invalid checksum error, all three times I downloaded it. I saw a Twitter post from someone else who had the same problem.

Answer 5

At the risk of redundancy, I'll post my answer as well, since I tried everything on this page (and many others) and ended up with a hybrid of some of them which seemed the most likely to work. Note that some of these steps may not have been explicitly necessary but they were sufficient (i.e., I didn't go back and remove potentially unnecessary steps to get the simplest path to success).
Environment: Mac OS Lion 10.7.3, Homebrew components, rvm 1.10.2, ree 1.8.7-2012.01, Xcode 4.2.1 with legacy gcc-4.2 available.
Steps:
Ensure that a stable Ruby is current. Used 1.9.2 (rvm use 1.9.2) as 1.9.3 was a potential problem.
rm -fr $rvm_path/usr
rvm pkg install ree_dependencies
rvm remove ree
export CC=/usr/bin/gcc-4.2
rvm install ree \
--with-openssl-dir=$rvm_path/usr \
--with-readline-dir=$rvm_path/usr \
--with-iconv-dir=$rvm_path/usr \
--with-zlib-dir=$rvm_path/usr
I had previously tried the brew-specific solutions but those didn't work for me. Hope this helps someone!

Answer 6

Please do NOT use sudo with RVM, nor do you need to use rvmsudo EXCEPT for when upgrading RVM itself. Please see and read https://rvm.io/support/faq/ (Do I need to use sudo with gems? entry) and https://rvm.io/support/troubleshooting/ (Multi-User Installs - Using the sudo command entry)
Please remove your current installation and start over as using sudo will definitely mess up the permission structure for RVM. Please see the very bottom of https://rvm.io/support/troubleshooting/ (How do I completely clean out all traces of RVM from my system, including for system wide installs? entry)
Then begin again strictly following the Multi-User installation segment of https://rvm.io/rvm/install/
Thank you.

If you are on Lion 10.7.2, and have installed XCode 4.2, you need to downgrade XCode to 4.1
Here's how I did it (it was more complicated than you might think):
Download XCode 4.1 from Apple Dev Center (you'll need to login with your dev centre creds)
uninstall XCode 4.2
$ sudo /Developer/Library/uninstall-devtools --mode=all
remove the XCode installer from your /Applications directory
run the XCode 4.1 package you downloaded, this will install a new XCode installer into /Applications
run the XCode installer in /Applications
When it stops, asking you to quit iTunes, you need to quit iTunes, and also use Activity Monitor to force quit the iTunes Helper
Wait for XCode 4.1 to install
Use the steps outlined above to install ree
Cheers,
Ian
