我尝试键入以下命令: pip3 install --user psycopg2 psycopg2-binary
重击答案: 错误:正在运行安装
It appears you are missing some prerequisite to build the package from source.
You may install a binary package by installing 'psycopg2-binary' from PyPI.
If you want to install psycopg2 from source, please install the packages
required for the build and try again.
For further information please check the 'doc/src/install.rst' file (also at
<http://initd.org/psycopg/docs/install.html>).

您无法安装psycopg2,因为设备中的gcc编译器已经过时且无法安装和运行它,或者它不存在。
如果您仅运行pip install psycopg2-binary
,则它将在您的开发和测试环境中运行,但是不建议在生产环境中使用。
要安装psycopg2,请通过运行以下命令确保已在设备中安装了gcc-
gcc --version
gcc where
如果尚未安装,请参考此处的指南进行安装-
我希望这会有所帮助。 :)
