Question

注意：此问题与How can I get bundler to use the Ruby version set by chruby and .ruby-version?有关。

使用chruby我在macOS上安装了Ruby 1.8.7：

$ ruby -v
ruby 1.8.7 (2013-06-27 patchlevel 374) [i686-darwin17.4.0]

另外，我使用gem update --system 1.8.30来安装特定版本的RubyGems，我希望它是兼容的。这似乎安装正确：

$ gem --version
1.8.30

但是，我的RubyGems环境显示了不正确的Ruby版本（2.5.0）：

$ gem env
RubyGems Environment:
  - RUBYGEMS VERSION: 1.8.30
  - RUBY VERSION: 2.5.0 (2017-12-25 patchlevel 0) [x86_64-darwin17]
  - INSTALLATION DIRECTORY: /Users/keithpitty/.gem/ruby/1.8.7
  - RUBY EXECUTABLE: /usr/local/opt/ruby/bin/ruby
  - EXECUTABLE DIRECTORY: /Users/keithpitty/.gem/ruby/1.8.7/bin
  - RUBYGEMS PLATFORMS:
    - ruby
    - x86_64-darwin-17
  - GEM PATHS:
     - /Users/keithpitty/.gem/ruby/1.8.7
  - GEM CONFIGURATION:
     - :update_sources => true
     - :verbose => true
     - :benchmark => false
     - :backtrace => false
     - :bulk_threshold => 1000
  - REMOTE SOURCES:
     - http://rubygems.org/

如何修复RubyGems环境以使用chruby设置的Ruby版本？

Answer 1

我缺少的一步是从源代码安装RubyGems 1.6.2。根据{{3}}其他地方的建议，我做了以下工作：

curl -O https://rubygems.org/rubygems/rubygems-1.6.2.tgz

（然后解压缩）

cd rubygems-1.6.2
chruby ruby-1.8.7-p374
ruby setup.rb
gem update --system 1.8.25

然后修复了我的RubyGems环境：

$ gem env
RubyGems Environment:
  - RUBYGEMS VERSION: 1.8.25
  - RUBY VERSION: 1.8.7 (2013-06-27 patchlevel 374) [i686-darwin17.4.0]
  - INSTALLATION DIRECTORY: /Users/keithpitty/.gem/ruby/1.8.7
  - RUBY EXECUTABLE: /Users/keithpitty/.rubies/ruby-1.8.7-p374/bin/ruby
  - EXECUTABLE DIRECTORY: /Users/keithpitty/.gem/ruby/1.8.7/bin
  - RUBYGEMS PLATFORMS:
    - ruby
    - x86-darwin-17
  - GEM PATHS:
     - /Users/keithpitty/.gem/ruby/1.8.7
     - /Users/keithpitty/.rubies/ruby-1.8.7-p374/lib/ruby/gems/1.8
  - GEM CONFIGURATION:
     - :update_sources => true
     - :verbose => true
     - :benchmark => false
     - :backtrace => false
     - :bulk_threshold => 1000
