RVM ruby installation issue

Question

I've already got ruby and rails installed for some time and worked on some projects. Lately I've installed the Xcode 5 developer preview in order to get my apps ready for iOS 7. I'm just mentioning this in case the new Xcode messed it up.

I first noticed the error when trying to

rake asets:precompile

in the rails project directory. It gives the following error:

/Users/User/.rvm/bin/ruby: line 6: /Users/User/.rvm/bin/ruby: Argument list too long /Users/User/.rvm/bin/ruby: line 6: /Users/User/.rvm/bin/ruby: Undefined error: 0

When I try:

ruby -v

The terminal window gives no response at first, the terminal title flickers between "bash" and "env", but then shows the following error:

/Users/User/.rvm/bin/ruby: line 6: /Users/User/.rvm/bin/ruby: Argument list too long
/Users/User/.rvm/bin/ruby: line 6: /Users/User/.rvm/bin/ruby: Undefined error: 0

And when I try

rvm get stable

I get:

RVM reloaded!

And finally, when I enter:

rvm install ruby-2.0.0-p247

I get:

But its still the same as before.

As far as I know I haven't changed anything to the system, I've only installed the new Xcode. Does someone know whats wrong here? Unfortunately these rvm / ruby / terminal commands, or more precisely, how this ruby install path-permission-rights thing is still very new to me. Thank you very much for your time!

Answer 1

Looks like the error is occurring in your gem path. Are you sure the @global gemset exists? Running the following should clear up the issue.

rvm gemset create global

Answer 2

make sure your rvm is up to date:

rvm get stable

then you need to run:

rvm use ruby

this will ensure your environment is set up properly, it does display warnings if something is wrong, you need to read the warnings always - and follow the instructions

to make the use ruby persist for next shell sessions use:

rvm use --default ruby

it will create the default alias which is loaded when rvm is started
