Postgresql 在MacOS上安装do_postgres

我在这里完全不知所措。我的gem文件中有“dm postgres adapter”，这让我很头疼

当我在推到heroku之前在一个小应用程序上运行bundle install时，我会遇到以下问题：

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

Gem files will remain installed in /Library/Ruby/Gems/2.0.0/gems/do_postgres-0.10.14 for inspection.
Results logged to /Library/Ruby/Gems/2.0.0/gems/do_postgres-0.10.14/ext/do_postgres/gem_make.out

An error occurred while installing do_postgres (0.10.14), and Bundler cannot continue.
Make sure that `gem install do_postgres -v '0.10.14'` succeeds before bundling.

我花了几个小时在互联网上结结巴巴地转来转去，所以我将列出我尝试过但没有成功的地方：

通过brew完全重新安装postgresql。 使用pg config=PATH运行（或类似） 将postgres添加到我的路径 软链接gcc到gcc4.2

我知道mb/pg_wchar.h在哪里。它就在那里。我已经尝试了它列出的大多数选项，包括usr/local/cillar/postgresql/9.3.4/include/server/，但我尝试过的选项都不起作用。我认为值得注意的是，

postgres.h

与

mb/pg_wchar.h

位于

/server/

文件夹中的同一目录中

如果有人能对此有所了解，那就太好了。

这里似乎有一个相同的问题：尽管如此，仍然没有解决方案。
