Gem files will remain installed in /Users/Apple/.rvm/gems/ruby-2.2.2@/gems/pg-0.18.1 for inspection.

An error occurred while installing pg (0.18.1), and Bundler cannot continue.
Make sure that `gem install pg -v '0.18.1'` succeeds before bundling.

有人可以帮忙吗？

在我发现这个之前，我在新的 SO 中安装 pg gem 时遇到了很多问题：

bundle failing - Can't find the PostgreSQL client library (libpq)

希望对你有所帮助。
