Here's my RubyGems Environment:
- RUBYGEMS VERSION: 2.5.2
- RUBY VERSION: 2.2.2 (2015-04-13 patchlevel 95) [x86_64-darwin14]
- INSTALLATION DIRECTORY: /Users/wh026399/.rvm/gems/ruby-2.2.2
- USER INSTALLATION DIRECTORY: /Users/wh026399/.gem/ruby/2.2.0
- RUBY EXECUTABLE: /Users/wh026399/.rvm/rubies/ruby-2.2.2/bin/ruby
- EXECUTABLE DIRECTORY: /Users/wh026399/.rvm/gems/ruby-2.2.2/bin
- SPEC CACHE DIRECTORY: /Users/wh026399/.gem/specs
- SYSTEM CONFIGURATION DIRECTORY: /etc
- RUBYGEMS PLATFORMS:
- ruby
- x86_64-darwin-14
- GEM PATHS:
- /Users/wh026399/.rvm/gems/ruby-2.2.2
- /Users/wh026399/.rvm/gems/ruby-2.2.2@global
I was wondering what "USER INSTALLATION DIRECTORY" is. why it not point to gems under folder .rvm but .gem instead? Also, why is it using 2.2.0 which is a ruby version I didn't install?
回答1:
The User Installation Directory variable for RubyGems is the directory where gems will be installed when using the --user-install flag, which is a directory immediately within your home directory.
The User Installation Directory has always existed, but it was recently made more visible via pull 1343.
