postgresql - 无法让 postgresql 数据库找到 pg_config 文件

Question

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

 Gem files will remain installed in    /Users/markhoyt/Desktop/KeyToLife/KeyToLife/KEYTOLIFEPG/KeyToLifeApp/vendor/bundle/ruby/2.0.0/gems/pg-0.18.1 for inspection.

我已经为此工作了两天，并且已经尝试了所有我能从堆栈溢出中得到的东西。我已经安装了 PG 应用程序，尝试使用 pg config 定位和设置路径，但无法正确设置。

 locate pg_config
/usr/local/Cellar/postgresql/9.4.1/bin/pg_config
/usr/local/Cellar/postgresql/9.4.1/include/ecpg_config.h
/usr/local/Cellar/postgresql/9.4.1/include/pg_config.h

如有任何帮助，我们将不胜感激!

你运行的是什么操作系统？苹果 ？ GNU/Linux ？

如果您在 MacOS 上运行，一个不错的选择是 Postgres.app ( http://postgresapp.com )，它可能适合您的需要。它在各种框架上对我来说一直完美无缺。

另外，我猜你也检查了头文件？的输出是什么: 找到 libpq-fe.h？
