RVM doesn't set correct gem path

阅读更多关于 RVM doesn't set correct gem path

问题 On a clean OS X Snow Leopard install, I have a problem with RVM: It sets the ruby path correctly but doesn't set the gem path. When I start a rails server, it mixes versions which doesn't work. To illustrate: $ rvm system $ which ruby /usr/bin/ruby $ which rails /usr/bin/rails $ rvm use 1.9.2-head Using /Users/m/.rvm/gems/ruby-1.9.2-head $ rvm gem list LOCAL GEMS [...] rails (3.0.7) [...] $ which ruby /Users/m/.rvm/rubies/ruby-1.9.2-head/bin/ruby $ which rails /usr/bin/rails Any ideas what

RVM and thin, root vs. local user

阅读更多关于 RVM and thin, root vs. local user

问题 So I'm trying to get thin to run as a service with RVM. After a thin install I manually updated /etc/init.d/thin to use an su - user when running the config command so that thin was running as a local user, rather than root. So far so good. Now, when I try to sudo service thin start it looks like it's trying to use the non-RVM version of Ruby (1.8.7 which was installed on the box to start with) to actually execute the command. I did a gem install thin on the non-RVM version, which then gets

Issue updating Ruby on Mac with Xcode 4.3.1

阅读更多关于 Issue updating Ruby on Mac with Xcode 4.3.1

I'm using RVM to install it and it gives me this error: The provided compiler '/usr/bin/gcc' is LLVM based, it is not yet fully supported by ruby and gems, please read `rvm requirements`. I'm on Lion 10.7.3 and I have Xcode 4.3.1. shigeya Short answer is you can grab RVM master branch (not stable) to build it with LLVM (not gcc, I mistyped initially). It has appropriate patches to make 1.9.3-p125 to run (at least better) with Xcode 4.3.1 by default. I provided the patch. If you already installed RVM, rvm get head will install the master branch. With command line tools installed with Xcode 4.3

I've tried this but it didn't work and seemed to be for osx. I have a fresh Ubuntu 10.10 install with rvm, rails 3 and ruby 1.9.2.

问题 I'm trying to get a compile command (rake cucumber) to run with a specific ruby version on my Mac OS X system, I use rvm to do this currently in the terminal. My ~/.MacOSX/environment.plist has the correct path in it, but emacs insists on prepending to this path and therefore making it useless. I've also tried: (when (equal system-type 'darwin) (setenv "PATH" (concat "/Users/fearoffish/.rvm/bin:/Users/fearoffish/.rvm/rubies/ruby-1.8.7-p249/bin:/Users/fearoffish/.rvm/gems/ruby-1.8.7-p249/bin:
