每当我尝试使用pip时，我都会收到大量的警告。我如何才能摆脱这些警告？
例如，我试图升级我的pip。
C:\Windows\system32>pip install --upgrade pip

尝试使用选项
-q：pip install -q --upgrade pip根据文档（
pip install -h），使用选项-q一次可以消除警告消息，两次也可以消 debugging 误级别，三次也可以消除严重级别消息。如果你想将警告保存在一个文件中，以防以后需要读取它们，而只是不想在你的终端中看到它们，你可以用途：
pip install --upgrade pip 2> nameOfYourLog.File编辑20230409：
如果你没有使用cygwin或类似unix的东西，
pip install --upgrade pip 2> nameOfYourLog.File命令对你来说就不起作用了，但是根据在线文档，pip install -q --upgrade仍然可以完成它的工作。
