1.pip安装过程中报错，是因为是国外源
WARNING: Retrying (Retry(total=3, connect=None, read=None, redirect=None, status=None)) after connection broken by ‘ConnectTimeoutError(<pip._vend
or.urllib3.connection.HTTPSConnection object at 0x0000019A129144F0>, ‘Connection to files.pythonhosted.org timed out. (connect timeout=15)’)’: /packages/3b/7e/293d19ccd106119e35db4bf3e111b1895098f618b455b758aa636496cf03/setuptools-28.8.0-py2.py3-none-any.whl
这是因为python源在国外，所以会出现链接超时，永久设置pip源为国内源即可
pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple
2.设置国内源后仍然报错，是因为python3.10后不支持mysqlclient安装，将pip升级后再运行安装命令：
python -m pip install --upgrade pip

尝试安装pymysql仍然报错：

WARNING: Error parsing dependencies of celery: Expected matching RIGHT_PARENTHESIS for LEFT_PARENTHESIS, after version specifier
pytz (>dev)这个警告信息表明 Python 在解析 celery 库的依赖项时遇到了问题。具体的问题出在 pytz (>dev) 这个依赖项上。在 Python 的依赖项规范中，版本号后的括号 (>dev) 是不合法的。
5.尝试直接安装 pytz，然后再安装 celery
