Python项目安装包报错 python setup.py egg_info did not run successfully

在安装crcmod时报错，完整错误如下 ``` Collecting crcmod==1.7 Using cached crcmod-1.7.tar.gz (89 kB) Preparing metadata (setup.py) ... error error: subprocess-exited-with-error × python setup.py egg_info did not run successfully. │ exit code: 1 ╰─> [6 lines of output] usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...] or: setup.py --help [cmd1 cmd2 ...] or: setup.py --help-commands or: setup.py cmd --help error: invalid command 'egg_info' [end of output] note: This error originates from a subprocess, and is likely not a problem with pip. error: metadata-generation-failed ``` 原因是setuptools版本不对，升级到最新版本 ``` pip install --upgrade setuptools ``` 升级setuptools时报错 ``` ERROR: Could not install packages due to an OSError: [Errno 13] Permission denied: 'override.py' Check the permissions. ``` 权限不够，修改项目下所有目录的权限 ``` sudo chmod -R 777 /xx/xxx ``` 修改权限完成后，再使用命令升级 setuptools，完成后安装新包
