Question

使用这个SO回答How do you use multiple rails versions with rbenv?，我试图使用rbenv（而不是rvm）来设置一个环境来管理不同版本的Ruby和Rails。答案首先说是以这种方式安装链接到ruby版本的Rails版本。

RBENV_VERSION=1.9.3-p327 rbenv exec gem install rails --version 3.2.10

这对我有用。安装了Rails。

按照其说明，我尝试使用该版本的rails

以这种方式创建一个新项目

RBENV_VERSION=1.9.3-p327 rbenv exec rails _3.10.2_ new newprojectname

这对我没有用。我收到有关

的错误消息

    from /Users/michaeljohnmitchell/.rbenv/versions/1.9.3-p327/bin/rails:22:in `<main>'

因此我尝试安装铁路

gem install railties

有效

Successfully installed railties-3.2.10
1 gem installed
Installing ri documentation for railties-3.2.10...
Installing RDoc documentation for railties-3.2.10...

但是，尝试再次创建项目

RBENV_VERSION=1.9.3-p327 rbenv exec rails _3.10.2_ new newprojectname

创建了关于railties的相同错误消息

see error message above

我甚至尝试再次安装铁路，但使用RBENV前缀

RBENV_VERSION=1.9.3-p327 rbenv exec gem install railties

它再次安装！但是，当我尝试创建新项目时，我收到了相同的错误消息。

Answer 1

我遇到了同样的问题，

这就是我所做的我删除了〜/ .gemrc

接下来，我跑了gem env
看它是否指向正确的地方：
RubyGems环境：
   - RUBYGEMS版本：2.0.3
   - RUBY VERSION：2.0.0（2013-02-08 patchlevel -1）[x86_64-linux]
   - 安装目录：/home/[yourpath]/.rbenv/versions/2.0.0-rc2/lib/ruby/gems/2.0.0
   - RUBY EXECUTABLE：/home/[yourpath]/.rbenv/versions/2.0.0-rc2/bin/ruby
   - 可执行目录：/home/[yourpath]/.rbenv/versions/2.0.0-rc2/bin
   - RUBYGEMS PLATFORMS：
     - 红宝石
     - x86_64-linux
   - 创业板路径：
      - /home/[yourpath]/.rbenv/versions/2.0.0-rc2/lib/ruby/gems/2.0.0
      - /home/[yourpath]/.gem/ruby/2.0.0    - 创业板配置：
      - ：update_sources =＆gt;真正
      - ：verbose =＆gt;真正
      - ：backtrace =＆gt;假
      - ：bulk_threshold =＆gt; 1000
   - 远程来源：
      - https://rubygems.org/

然后我试图再次安装宝石

gem install rails

现在安装到正确的地方:)
如果它适用于你，请告诉我

安装了铁路但未找到
