问题
I am trying to install Ruby 1.9.3 but am having problems. I installed RVM, then typed:
rvm install 1.9.3
The output says:
ERROR: Error running ' ./configure....
The log says:
configure: WARNING: unrecognized options: --with-libyaml-dir
checking build system type... x86_64-apple-darwin11.2.0
checking host system type... x86_64-apple-darwin11.2.0
checking target system type...x86_64-apple-darwin11.2.0
checking whether the C compiler works... no
configure: error: in `/Users/myuser/.rvm/src/ruby-1.9.3-p0':
configure: error: C compiler cannot create executables See `config.log' for more details
I downloaded the new XCode from the App Store and installed it.
回答1:
Try using the clang compiler instead of the default:
rvm install 1.9.3 --with-gcc=clang

RVM needs gcc-4.2 to be able to install ruby 1.9.3. Unfortunately Lion does not include anymore gcc-4-2, just the llvm version:
lrwxr-xr-x 1 root wheel 12 15 feb 17:21 /usr/bin/gcc -> llvm-gcc-4.2
If you have Lion but upgraded from Snow Leopard it is likely that you still have gcc-4.2 If you have a brand new installation of Lion you should download gcc-4.2. I recommned downloading this package.

Check that you have gcc-4.2 installed now:
-rwxr-xr-x 1 root wheel 113024 16 may 2011 /usr/bin/gcc-4.2
lrwxr-xr-x 1 root wheel 12 15 feb 17:21 /usr/bin/gcc -> llvm-gcc-4.2
Now you can install ruby 1.9.3 as usual:
rvm install 1.9.3
rvm use 1.9.3 --default

If you want to merely install and keep up to date the latest version of Ruby (as opposed to switching between different versions of ruby), you can install ruby via homebrew:
brew install ruby

Try this first:
rvm get latest
This is what I have working:
rvm:
version: "rvm 1.9.2 by Wayne E. Seguin (wayneeseguin@gmail.com) [https://rvm.beginrescueend.com/]"
ruby:
interpreter: "ruby"
version: "1.9.3p0"
date: "2011-10-30"
platform: "x86_64-darwin11.2.0"
patchlevel: "2011-10-30 revision 33570"
full_version: "ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-darwin11.2.0]"

Actually, ruby-1.9.3-p125 now works with gcc-llvm. But, the current stable/latest releases of rvm do not (yet). But that was just rvm being cautious and there's now a fix to that workaround in the master branch of rvm.
Simply, upgrade rvm to the master branch and install/upgrade ruby:
GT-MBP:~ gthiruva$ rvm upgrade ruby-1.9.3-p0 1.9.3

- Open Xcode
- Open Xcode preferences
- Open Downloads tab
- Check Command Line Tools
回答7:
- Uninstall/remove all traces of manually installed old ruby versions and extras (sqlite3, libxml2-x.x.x, libxslt-x.x.x) from your /usr/local/ or wherever you installed them.
- Download and install JewlryBox http://unfiniti.com/software/mac/jewelrybox which is a RVM GUI interface for managing your rubies and gemsets.
- In JewlryBox, click "Add Ruby" and choose the version of ruby you want to install (I chose 64 bit, Enabled Shared and didn't check/tick the "Use clang" option).
Worked with OS X Lion 10.7.3 and Xcode 4.3 Command Line Tools installed.

Type following commands
- ~ $: source ~/.rvm/scripts/rvm
- ~ $: type rvm | head -n 1
rvm is a function
~ $: vi ~/.bash_profile add this line into bash_profile "source ~/.rvm/scripts/rvm"
~ $: rvm install 1.9.3
- ~ $: rvm use 1.9.3

Clang wasn't cutting any rubies for me and rvm install rubies failed no matter what with single user rvm. Sudo combined with some permission & $PATH changes to my user made it happen. Here's what I did:
sudo bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer )</pre>
sudo rvm pkg install readline
sudo rvm install 1.9.3
Installing rvm from root user makes a shell script at /usr/local/rvm/scripts/rvm Pulled code from this executable and placed it in my .bash_profile so that .bash_profile was saved as:
[ -s "/usr/local/rvm/scripts/rvm" ]] ;
true ${rvm_path:="/usr/local/rvm"}
source "/usr/local/rvm/scripts/rvm"
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function
The user group RVM was created during root user rvm install. Last thing I did was go to my preferences pane in OSX 10.7 and added my user to the new rvm group. Finally I reloaded my terminal and was able to install 1.9.3 through rvm single user.

Using rvm, ruby 1.9.3, and attempting to use gcc, I couldn't get Ruby to build cleanly with yaml. While there are a variety of hacks to get yaml compilation to work, none of them seemed to work with rvm. I was troubleshooting late at night and I didn't retain my errors, so I'm working from memory here -- I would appreciate if someone else with a clean environment could test these steps.
Using the --with-gcc=clang solution produced the mildly infamous error about the yaml parser:
It seems your ruby installation is missing psych (for YAML output). To eliminate this warning, please install libyaml and reinstall your ruby.
Since I need yaml for what I'm going to be doing, and libyaml compiled fine when not being run by rvm, and I even had it installed in /usr/lib after building it by hand, I can't understand why rvm couldn't find and use that version of libyaml, even with the --shared-libs option.
Using CC=/usr/bin/gcc rvm install 1.9.3 produced errors. In the .rvm/log/ruby-1.9.3-p385/configure.log, I found the following:
configure: error: C compiler cannot create executables
See `config.log' for more details
That error was also present in .rvm/log/libyaml-0.14/configure.log.
The solution for me ended up being to run the rvm command with sudo. Running a compile as root seems to remove Apple's GCC toolchain's disapproval of users doing anything as dirty as compiling software.
So sudo CC=/usr/bin/gcc rvm install 1.9.3 --disable-binary gave me a clean compile of ruby+yaml in the rvm folder. I then needed to sudo chown -R username ~/.rvm && sudo chgrp -R staff ~/.rvm to get things back in my user and running with my permissions.
I do not recommend compiling things as root, as I see it as a security risk (especially with the vulnerabilities found in the ruby stack and rubygems.org recently) -- but this produced a clean installation of ruby under rvm and might help someone with more talent or time figure out the root cause of the issue with Apple's gcc.

With the new Feb 2012 Command Line Tools for Xcode, using RVM 1.10.3 (and JweleryBox for Mac) Ruby 1.9.3-p125 compiles fine, without "Use clang" and with shared linking and 64 bit architecture. More over, the "gem install rails" command works flawlessly without the warning about libyaml support.
