每当我尝试运行pip install psycopg2时，我都会收到上述错误。我试着下载编译版本，但是当我运行它时，我得到一个错误，告诉我必须安装Python 3.5。我安装了Python 3.5 x86，并且我下载了x86版本的psycopg2来匹配它，所以我真的找不到解决方案。有人有主意吗？我正在运行Windows 10。

Answer 1

在Windows 10上没有问题地安装了 psycopg2 ：

pip install psycopg2

确保您具有PostgreSQL可执行文件（包括）。 DLL位于您的PATH中：

%PG_HOME%\bin;%PG_HOME%\lib

Answer 2

只需安装C ++生成工具

然后，pip install psycopg2。并且您应该看到：
