python pip3 安装psycopg2报错
[root@edb ~]$ pip3 install psycopg2
Defaulting to user installation because normal site-packages is not writeable
Collecting psycopg2

Preparing metadata (setup.py) … error
error: subprocess-exited-with-error× python setup.py egg_info did not run successfully.
│ exit code: 1
╰─> [1 lines of output]
ERROR: Can not execute `setup.py` since setuptools is not available in the build environment.
[end of output]note: This error originates from a subprocess, and is likely not a problem with pip.
error: metadata-generation-failed× Encountered error while generating package metadata.
╰─> See above for output.note: This is an issue with the package mentioned above, not pip.
hint: See above for details.
最后倒数第二句说的是包的问题,不是pip命令的问题,说明python安装的是没问题的,解决方案:
[root@edb ~]$ pip3 install --upgrade setuptools
[root@edb ~]$ pip3 install psycopg2
