什么是“用户安装目录"?在rubyGems env中 [英] What is "USER INSTALLATION DIRECTORY" in rubyGems env

问题描述

这是我的RubyGems环境:

Here's my RubyGems Environment:

• RUBYGEMS版本:2.5.2
• 红宝石版:2.2.2(2015-04-13补丁程序级别95)[x86_64-darwin14]

• 用户安装目录:/Users/wh026399/.gem/ruby/2.2.0
• 可执行的RUBY:/Users/wh026399/.rvm/rubies/ruby-2.2.2/bin/ruby
• 可执行目录:/Users/wh026399/.rvm/gems/ruby-2.2.2/bin

    我想知道什么是用户安装目录".为什么它不指向文件夹.rvm下的gems而是指向.gem?另外，为什么使用我未安装的红宝石版本2.2.0?

    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?

    推荐答案

    RubyGems的用户安装目录变量是使用--user-install标志时将gem安装到的目录，该标志位于主目录中.

    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.

    用户安装目录一直存在，但是最近通过推1343 使其更加可见a>.

    The User Installation Directory has always existed, but it was recently made more visible via pull 1343.
