【中文标题】我无法安装 psycopg2 [重复]【英文标题】：I can't install psycopg2 [duplicate] 【发布时间】：2021-02-01 02:35:21 【问题描述】：我已经尝试使用 python 一段时间了，但在 pip 和安装模块方面遇到了麻烦。我安装了 pycharm 以查看它是否会处理任何错误的 python 安装。然后我尝试运行命令： pip install psycopg2 并得到以下错误（提前谢谢！）：

【问题讨论】：
改为安装psycopg2-binary
这能回答你的问题吗？ Can't install psycopg2 with pip in virtualenv on Mac OS X 10.7
二进制版本的工作方式一样吗？
【参考方案1】：
通常你可以直接安装一个预构建的二进制文件，所以你不需要收集依赖并在本地编译它：
$ pip install psycopg2-binary
您可以在此处找到有关此主题的更多信息：
