Mac + virtualenv + pip + postgresql =错误:找不到pg_config可执行文件 [英] Mac + virtualenv + pip + postgresql = Error: pg_config executable not found

问题描述

我正在尝试为教程安装postgres，但是pip给我错误:

I was trying to install postgres for a tutorial, but pip gives me error:

pip install psycopg

我得到的一小段错误:

Error: pg_config executable not found.

Please add the directory containing pg_config to the PATH

or specify the full executable path with the option:

    python setup.py build_ext --pg-config /path/to/pg_config build ...

or with the pg_config option in 'setup.cfg'.

virtualenv中的pg_config在哪里?如何配置呢?我使用virtualenv是因为我不想在系统范围内安装postgres.

Where is pg_config in my virtualenv? How to configure it? I'm using virtualenv because I do not want a system-wide installation of postgres.

推荐答案

在Mac上，如果您使用的是 Postgres.app ，pg_config文件位于您的/Applications/Postgres.app/Contents/Versions/<current_version>/bin目录中.需要将其添加到您的系统路径中，以解决此错误，例如:

On the Mac, if you're using Postgres.app, the pg_config file is in your /Applications/Postgres.app/Contents/Versions/<current_version>/bin directory. That'll need to be added to your system path to fix this error, like this:

export PATH=$PATH:/Applications/Postgres.app/Contents/Versions/<current_version>/bin

例如，如果当前Postgres.app版本为9.5，则此导出行将为:

So for example, if the current Postgres.app version is 9.5, this export line would be:

export PATH=$PATH:/Applications/Postgres.app/Contents/Versions/9.5/bin

使用Postgres.app的最新版本(> 9.5吗?)，您可以简单地添加"latest"代替版本号，就像这样:

With more recent versions of the Postgres.app (> 9.5?), you can simply add "latest" in place of the version number, like so:

export PATH=$PATH:/Applications/Postgres.app/Contents/Versions/latest/bin
