无法使用Postgres.app在小牛中安装pg gem [英] Cannot install pg gem in Mavericks with Postgres.app

问题描述

我正在尝试在本地计算机上安装pg gem与Postgres.app一起使用.我在跑小牛.

I am trying to install the pg gem for use with Postgres.app on my local machine. I am running Mavericks.

Postgres.app已安装并且运行良好，但是我无法运行gem.我已完成以下操作:

Postgres.app is installed and running fine, but I cannot get the gem to work. I've done the following:

1. 使用Postgres.app文档中的命令'env ARCHFLAGS =-arch x86_64" gem install pg---with-pg-config =/Applications/Postgres.app/Contents/MacOS/bin/pg_config
2. 更新了Homebrew并安装了Apple GCC 4.2
3. 安装了Xcode开发人员工具
4. 更新了我的$ PATH以同时引用Postgres.app bin目录和lib目录

所有操作均未成功.这是我收到的特定错误消息:

All with no success. Here is the specific error message I receive:

Building native extensions with: '--with-pg-config=/Applications/Postgres.app/Contents/MacOS/bin/pg_config'
This could take a while...

Could not create Makefile due to some reason, probably lack of necessary

need configuration options.

Provided configuration options:

    --without-opt-include=${opt-dir}/include
    --with-opt-lib

    --with-pg-lib

非常感谢您能提供的任何帮助.谢谢！

I'd appreciate any help you can offer. Thanks!

推荐答案

您可能使用了错误的--with-pg-config路径，请检查它是否确实存在.

You probably have the wrong path for --with-pg-config, check if it's actually there.

您可以使用以下方法找到指向pg_config的正确路径:

You can find the correct path to pg_config with:

find /Applications -name pg_config

在最新的Postgres.app版本中，路径为:

In the latest Postgres.app Version the path is:

gem install pg -- --with-pg-config=/Applications/Postgres.app/Contents/Versions/9.5/bin/pg_config
