我在这里完全不知所措。我的宝石文件中有`dm-postgres-adapter'，这让我很头疼。
当我在推送到heroku之前在一个小应用程序上运行bundle install时，我遇到了这个：
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.
我花了最后几个小时在互联网上磕磕绊绊，所以我会列出我试图无效的内容：
通过brew完全重新安装postgresql。
与--with-pg-config=PATH（或类似的东西）一起运行
将postgres添加到我的路径中
软链接gcc到gcc4.2
我知道mb / pg_wchar.h位于何处。它在/usr/local/Cellar/postgresql/9.3.4/include/server/mb/pg_wchar.h/就在那里。我已尝试用usr/local/Cellar/postgresql/9.3.4/include/server/列出的大多数选项，但我尝试过的都没有。我认为值得注意的是postgres.h与mb/pg_wchar.h文件夹中的/server/位于同一目录中。
如果有人能够对此有所了解，那就太棒了。
