可能重复：
无法在 ubuntu 上安装 pg gem - 找不到 'libpq-fe.h 标头

我正在尝试将 gem pg添加到我的本地环境中。
但它返回此错误

Errno::EACCES: Permission denied - /Users/me/.rvm/gems/ruby-1.9.3-p362/gems/pg-0.14.1/.gemtest
An error occurred while installing pg (0.14.1), and Bundler cannot continue.
Make sure that `gem install pg -v '0.14.1'` succeeds before bundling.

我应该怎么办？

在该错误消失后，现在它返回此错误

我相信你在尝试之前会弄乱 sudo

chown -R `whoami`:staff ~/.rvm/gems/ruby-1.9.3-p362/gems

看起来有人过去曾试图以 sudo 的形式安装它。我会检查该目录的权限，如果文件看起来有问题，我会 chown 文件。
