1.pip更新之前都是:python -m pip install --upgrade pip 2.但今天一直提示有错误,试过输入:python -m pip install --upgrade pip -i https://pypi.douban.com/simple 3.也试过删除形如pip-21.0.3.dist-info的文件夹,再输入python -m pip install --upgrade pip 也是报错
4.后面发现了一行关键的报错语句:
ERROR: Could not install packages due to an OSError: [WinError 5] 拒绝访问。: 'C:\\Python39\\Lib\\site-packages\\pip\\__init__.py'
Consider using the `--user` option or check the permissions.
5.修改后尝试执行:pip install --user --upgrade pip 6.pip工具算是更新成功了,但这么多的警告我还是想弄掉 7.输入了:pip3 install pyinstaller -i https://pypi.tuna.tsinghua.edu.cn/simple -U 8.关键报错在于:
note: This error originates from a subprocess, and is likely not a problem with pip.
error: legacy-install-failure
× Encountered error while trying to install package.
╰─> future
note: This is an issue with the package mentioned above, not pip.
hint: See above for output from the failure.
WARNING: Ignoring invalid distribution -p (c:\python39\lib\site-packages)

9.参考网上的办法,删除以前版本的包即可,原因可能是之前下载库的时候没有成功或者中途退出。到提示的目录site-packages下删除。删除c:\python39\lib\site-packages目录下面的所有以波浪号开头的目录 10.终于正常了。 今天也是讨厌pip的一天
