RVM，Ruby和Rails安装中的gem问题

Question

I have been trying to get my dev environment setup on my computer for a number of days now, but without any luck. I've had more error messages than I could care to remember and my installation problems have been anything but consistent.

My current problem is unknown as I don't know where its stemming from.

When I try to check my gem version gem -v , the terminal locks up for a couple minutes and then gives me this output:

/Users/Riley/.rvm/bin/gem: line 6: /Users/Riley/.rvm/bin/gem: Argument list too long
/Users/Riley/.rvm/bin/gem: line 6: /Users/Riley/.rvm/bin/gem: Undefined error: 0

The entire contents of that file are as follows:

#!/usr/bin/env bash

if [[ -s "/Users/Riley/.rvm/environments/ruby-2.0.0-p0" ]]
then
  source "/Users/Riley/.rvm/environments/ruby-2.0.0-p0"
  exec gem "$@"
else
  echo "ERROR: Missing RVM environment file: '/Users/Riley/.rvm/environments/ruby-2.0.0-p0'" >&2
  exit 1
fi

And I don't have a clue what its supposed to be, if not that. Checking which ruby gives me:

/Users/Riley/.rvm/bin/ruby

And the problem really seems to come alive when I try to install rails, gem install rails :

ERROR:  Loading command: install (LoadError)
cannot load such file -- openssl
ERROR:  While executing gem ... (NoMethodError)
undefined method `invoke_with_build_args' for nil:NilClass

** This error has ceased to occur and is now replaced with the above "line 6" error for gem -v , however I'm sure it will show up again.

I have also tried all of this:

rvm get head --autolibs=3
rvm pkg remove
rvm reinstall all --force

and all the other renditions of solutions on SO and many other sites.

I would greatly appreciate someone helping me with this setup as I don't have any solution to my problem outside of google and SO.

Answer 1

The problem stemmed from my installation of Ruby. Apparently, as stated in this answer , "a non-LLVM version of GCC" is no longer included in the XCode command line tools.

Installing ruby with:

rvm install ruby --with-gcc=clang

Worked and I installed RVM, Ruby and Rails within about 10 minutes, despite it taking me a week of debugging and reinstalling otherwise.

Answer 2

Run rvm requirements and install all the dependencies as specified (openssl being one of them). It should fix your problem.
