当数据库在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

我的数据库与应用程序位于不同的服务器上.当我运行捆绑"时，出现以下错误:

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

没有 pg_config... 无论如何都在尝试.如果构建失败，请重试与 --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

如果应用服务器上没有实际安装 pg，如何设置 pg 配置路径?我也试过:

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

捆绑配置 build.pg --without-pg_config

bundle config build.pg --without-pg_config

谢谢

推荐答案

Ruby PostgreSQL 接口(又名 pg gem)只是 PostgreSQL 客户端 C 库的一个瘦包装器.您需要安装 PostgreSQL 客户端库和头文件，否则无法安装 pg gem.你不需要在你的应用服务器上安装完整的 PostgreSQL，只需要客户端开发库，这个包可能被称为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".
