【问题描述】：
我正在尝试在我的 rack/bundler 应用程序中安装 postgres gem "pg"，但在尝试通过 RubyMine 安装时一直失败。

An error occurred while installing do_postgres (0.10.13), and Bundler cannot
continue.
Make sure that `gem install do_postgres -v '0.10.13'` succeeds before bundling.
因此，出于某种原因，对于我当前的项目，如果我通过命令行安装 gem，它不会被添加到 Rubymine 的 External Libraries 文件夹中，并且到目前为止一直依赖于它自己的 bundle/gem 安装程序。因此，通过阅读其他问题，我看到下载了对 Mac os x 的 Postgres93 支持，并在命令行中尝试通过指定 pg_config 文件的路径来安装 postgres gem，它下载成功，但没有添加到Rubymine 项目中的库。
sudo gem install pg -- --with-pg config=/Applications/Postgres93.app/Contents/MacOS/bin/pg_config
上述命令有效，但没有导致 gem 出现在 Rubymine 中，因此我仍然无法推送到 Heroku。因此，当尝试向捆绑安装程序提供附加参数时，我在输入时遇到语法错误
--with-pg-config=/Applications/Postgres93.app/Contents/MacOS/bin/pg_config
有什么办法解决这个问题吗？
【问题讨论】：

现在带有参数的 sudo gem install pg 甚至不起作用。
