我如何找到安装gem文件的位置？ [英] How can I find where gem files are installed?

问题描述

我可以通过命令 gem list 找到安装哪个gem，但它并不显示安装gem的位置。

我如何才能找到宝石的位置，以及如何在安装gem之前知道安装位置？

使用 gem environment 查找关于你的宝石环境：

  RubyGems环境：

  -  RUBY VERSION ：2.0.0（2013-06-27 patchlevel 247）[x86_64-darwin12.4.0]

  -  / usr / local / bin 
  -  / usr / bin 
  -  / bin 
  -  / usr / sbin 
  -  / sbin 
  -  / usr / local / bin 
  

注意以下两部分：

• INSTALLATION DIRECTORY $ GEM PATHS



I can find which gem is installed by command gem list, but it doesn't show me where the gems are installed.

How can I find where the gems are and how can I know before installing a gem where it will be installed?

解决方案

Use gem environment to find out about your gem environment:
