通过 pip 安装 Python 模块

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？

答案1

您面临以下错误：

异常：pg_config 工具不可用。

该pg_config工具是libpq-dev

您可以使用以下方式安装：

sudo apt-get install libpq-dev
