Gem安装错误可写和PATH [英] Gem install errors writable and PATH

问题描述

这是我得到的两个错误。我在OS X.老实说，不知道我是否通过宝石安装 - 如果这很重要。

 警告：自/Library/Ruby/Gems/1.8和
 / usr / bin安装到〜/ .gem都不是可写的。 
警告：您的PATH中没有/Users/M/.gem/ruby/1.8/bin，
 gem可执行文件将无法运行。 
  

解决方案

系统管理员，因此您需要root权限来安装Gems。

c $ c>

第二个警告是因为没有root权限，Ruby会尝试在您的用户目录中安装Gem。但是，除非您在用户目录中安装了Ruby，否则稍后可能会遇到一些问题。

These are the two errors I am getting. I am on OS X. Honestly, don't know if I installed via gem or not - if that matters.

WARNING:  Installing to ~/.gem since /Library/Ruby/Gems/1.8 and
  /usr/bin aren't both writable.
WARNING:  You don't have /Users/M/.gem/ruby/1.8/bin in your PATH,
  gem executables will not run.

解决方案

The default Ruby installation shipped on Mac OS X is owned by the system administrator, so you need root privs to install Gems.

$ sudo gem install MYGEM

The second warning is because, without root privileges, Ruby tries to install the Gem in your user directory. However, unless you also installed Ruby in your user directory, you might encounter some problem later.
