解决BUG：error: metadata-generation-failed

BUG说明：

执行命令：pip install -r requirements.txt -i https://pypi.tuna.tsinghua.edu.cn/simple 时报错，经分析未检测单setuptools-57.5.0

具体报错如下：

  error: subprocess-exited-with-error    × python setup.py egg_info did not run successfully.  │ exit code: 1  ╰─> [1 lines of output]      error in ConcurrentLogHandler setup command: use_2to3 is invalid.      [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

解决方案：

在执行批量安装命令pip install -r requirements.txt -i https://pypi.tuna.tsinghua.edu.cn/simple之前，先执行pip install setuptools==57.5.0 -i https://pypi.tuna.tsinghua.edu.cn/simple 命令

成功解决：
