当数据库位于不同的服务器上时安装postgres gem [英] Installing postgres gem when database is on a different server

问题描述

我的数据库位于与应用程序不同的服务器上。当我运行捆绑我得到以下错误：

My database is on a different server to the application. When I run "bundle" I get the following error:

没有pg_config ...试试反正。如果构建失败，请再次尝试
with-with-pg-config = / path / to / pg_config

No pg_config... trying anyway. If building fails, please try again with --with-pg-config=/path/to/pg_config

如果pg实际上没有安装在应用程序服务器上，我设置pg配置路径？我也尝试过：

How do I set the pg config path if pg is not actually installed on the application server? I have also tried:

bundle config build.pg --without-pg_config

bundle config build.pg --without-pg_config

感谢

推荐答案

Ruby PostgreSQL接口（AKA的pg gem）包装在PostgreSQL客户端C库。您需要安装PostgreSQL客户端库和标题，或者您不能安装pg gem。你不需要在应用服务器上安装一个完整的PostgreSQL，只需要客户端开发库，这个包可能叫做libpg-dev或libpq-dev。

The Ruby PostgreSQL interface (AKA the pg gem) is just a thin wrapper around the PostgreSQL client C libraries. You need to install the PostgreSQL client libraries and headers or you can't install the pg gem. You don't need a whole PostgreSQL installation on your app server, just the client development libraries, the package is probably called something like "libpg-dev" or "libpq-dev".
