与 RVM 一起安装时找不到 Rails 命令行 [英] Rails command line not found when installed with RVM

问题描述

安装 RVM 后，我安装了 Ruby 1.8.7，然后是 Rails 3.当我执行 which rails 我得到 /Users/davidbenhamou/.rvm/gems/ruby-1.8.7-p302/bin/rails.但是当我执行 rails -v 我得到 -bash:/usr/bin/rails: No such file or directory

After installing RVM, I have installed Ruby 1.8.7 then Rails 3. When I do which rails I get /Users/davidbenhamou/.rvm/gems/ruby-1.8.7-p302/bin/rails. But when I do rails -v I get -bash: /usr/bin/rails: No such file or directory

为什么 Rails 不工作?注意:我遵循了 RVM 网站上的所有步骤，Ruby 命令行工作正常 (ruby -v).

Why is Rails not working? Note: I have followed all steps from RVM website and Ruby command line work fine (ruby -v).

推荐答案

要查看您已安装的 rubies:

To see the rubies you have installed:

rvm list rubies

你会看到这样的:

   ree-1.8.7-2011.03 [ i686 ]
*  ruby-1.9.2-p290 [ x86_64 ]
   ruby-1.9.3-p0 [ x86_64  ] 
=> ruby-1.9.3-p125 [ x86_64 ]
   ruby-1.9.3-p125-perf [ x86_64 ]

要使用特定的:

rvm use ruby-1.9.3-p125

然后如果你执行 ruby --version，你会看到:

then if you do ruby --version, you'll see:

ruby 1.9.3p125 (2012-02-16 revision 34643) [x86_64-darwin10.7.0]

在每个这些红宝石中，您需要安装所有要使用的宝石.我这样做的方法实际上是使用 Bundler 为项目安装所有 gem.但是对于这里的简单情况，只需执行以下操作:

In each of these rubies you need to install all the gems you want to use. The way I do it is actually by using Bundler to install all the gems for a project. But for the simple case here, just do:

rvm all do gem install rails

这将在 所有 ruby​​ 版本中安装 rails gem.要安装到特定的，请使用:

This will install the rails gem in all your ruby versions. To install to a particular one, use:

rvm ruby-1.9.3-p125  do gem install rails
