通过pip为python安装模块

Question

我尝试在 Ubuntu 14.04.3 (x86_64) 中通过 pip3 安装“PyGreSQL”（pgdb）模块

pip3 install PyGreSQL

但我有一个错误：

• python --version - Python 3.4.3

• which pip3 —— /usr/bin/pip3

你能帮我解决这个问题吗？

您正面临以下错误：

例外：pg_config 工具不可用。

该pg_config工具是libpq-dev

您可以使用以下方法安装它：

sudo apt-get install libpq-dev
