每当我运行它时，brew 和 gem 都会抛出“权限被拒绝”错误

Question

每当我运行“gem”或“brew”时都会发生这种情况：

/Library/Ruby/Site/2.0.0/rubygems/stub_specification.rb:75:in `initialize': Permission denied - /Library/Ruby/Gems/2.0.0/specifications/cocoapods-plugins-0.4.2.gemspec (Errno::EACCES)

我也安装了 cocoapods，当我检查文件夹时（/Library/Ruby/Gems/2.0.0/specifications/）：

-rw-------   1 root  wheel  1599 Apr  9 22:41 cocoapods-plugins-0.4.2.gemspec
-rwxr-xr-x   1 root  wheel  1376 Jun 27  2014 cocoapods-trunk-0.1.3.gemspec
-rwxr-xr-x   1 root  wheel  1376 Sep  4  2014 cocoapods-trunk-0.1.4.gemspec
-rw-------   1 root  wheel  1290 Apr  9 22:41 cocoapods-trunk-0.6.0.gemspec
-rwxr-xr-x   1 root  wheel   980 Apr 27  2014 cocoapods-try-0.2.0.gemspec

-rw-------   1 root  wheel   980 Apr  9 22:41 cocoapods-try-0.4.3.gemspec

似乎我没有 -r 读取权限，当我使用“sudo”时它们都运行良好，有人知道我做错了什么吗？无论是我安装 gem 还是 ruby​​ 的方式，对不起，我是 Ruby 和 Gems 的完整 n00b。我的 gem 命令位于 '/usr/bin/gem' 而我的 brew 命令位于 'usr/local/bin/brew' 非常感谢！

您似乎是从 root 帐户安装它并尝试从没有权限的用户运行。
