Fedora 21 - Gem：更改可执行目录

我在我的环境中使用一些本地安装的 gem，我想将路径更改EXECUTABLE DIRECTORY为~/.gem/bin

我怎样才能实现这个目标？

$gem env

  - RUBYGEMS VERSION: 2.2.2
  - RUBY VERSION: 2.1.5 (2014-11-13 patchlevel 273) [x86_64-linux]
  - INSTALLATION DIRECTORY: /home/flyer/.gem/ruby
  - RUBY EXECUTABLE: /usr/bin/ruby
  - EXECUTABLE DIRECTORY: /home/flyer/bin
  - SPEC CACHE DIRECTORY: /home/flyer/.gem/specs
  - RUBYGEMS PLATFORMS:
    - ruby
    - x86_64-linux
  - GEM PATHS:
     - /home/flyer/.gem/ruby
     - /usr/share/gems
     - /usr/local/share/gems
  - GEM CONFIGURATION:
     - :update_sources => true
     - :verbose => true
     - :backtrace => false
     - :bulk_threshold => 1000
  - REMOTE SOURCES:
     - https://rubygems.org/
  - SHELL PATH:
     - /usr/local/bin
     - /usr/local/sbin
     - /usr/bin
     - /usr/sbin
     - /bin
     - /sbin
     - /home/flyer/.local/bin
     - /home/flyer/bin
     - /home/flyer/.local/bin
     - /home/flyer/bin

答案1

如果你的目的是安装 gems 的可执行文件到~/.gem/bin，您可以设置~/.gemrc：

gem:
 --bindir ~/.gem/bin 
 # any other gem settings like: 
 --no-ri --no-rdoc

它不会改变EXECUTABLE DIRECTORY，但 gems 的可执行文件将被安装到~/.gem/bin。你可以检查它是否已设置：

$ gem env
- GEM CONFIGURATION:
     - "gem" => "--bindir ~/.gem/bin --no-ri --no-rdoc"

为了能够调用它们，请将该目录添加到PATH.

答案2

你可以试试

$ export GEM_HOME = ~/.gem

这会将您的 gem 可执行目录更改为~/.gem/bin

$ gem env您可以通过再次运行来确认

如果有效，你可以export GEM_HOME=$HOME/.gem在文件末尾添加 .bashrc 或 .zshrc来使其永久生效

希望有帮助！

答案3

以下是.bashrc / .zshrc：

#Ruby + GEM
export GEM_HOME=$HOME/.gem
export PATH=$GEM_HOME/bin:$PATH

此后，我的所有宝石都开始发挥作用。
