使用 Bundler、RVM 和 RubyGems

Question

我似乎在这里遇到了一个奇怪的问题，不知道在哪里调试它。我已经在我的机器上安装了一段时间的 Ruby，但今天添加了 RVM。所以我将完成我正在采取的步骤：

我的宝石文件：

source 'https://rubygems.org'
gem 'capistrano', '~> 3.1.0'

尝试安装：

$ bundle
Fetching gem metadata from https://rubygems.org/.......
Installing rake (10.2.1) 
Gem::InstallError: rake requires Ruby version >= 1.9.
An error occured while installing rake (10.2.1), and Bundler cannot continue.
Make sure that `gem install rake -v '10.2.1'` succeeds before bundling.

检查 Ruby 版本，大于 1.9：

$ ruby -v
ruby 2.0.0p247 (2013-06-27 revision 41674) [universal.x86_64-darwin13]

确保已安装 rake：

$ gem list

*** LOCAL GEMS ***

...
rake (10.2.1)
...

尝试安装 rake：

$ sudo gem install rake -v '10.2.1'
Successfully installed rake-10.2.1
Parsing documentation for rake-10.2.1
1 gem installed

确保已安装 rake：

$ gem list

*** LOCAL GEMS ***

...
rake (10.2.1)
...

再试一次：

$ bundle
Fetching gem metadata from https://rubygems.org/.......
Installing rake (10.2.1) 
Gem::InstallError: rake requires Ruby version >= 1.9.
An error occured while installing rake (10.2.1), and Bundler cannot continue.
Make sure that `gem install rake -v '10.2.1'` succeeds before bundling.

也许是一些有用的信息：

$ rvm info

system:

  system:

谢谢。

Answer 1

我的解决方法是：

$ rvm reinstall 2.1.1

似乎，当我第一次安装此版本时，它没有正确完成并且没有更新所有路径。所以 gem install 将我的 gem 安装在错误的位置。
