当我使用pip时，我怎样才能摆脱"warnings"

Question

每当我尝试使用pip时，我都会得到大量的警告。我怎样才能摆脱这些呢?

例如，我试图升级我的pip。

C:Windowssystem32>pip install --upgrade pip

我尝试升级我的pip，但是它不工作。

Answer 1

尝试使用选项-q:

pip install -q --upgrade pip

根据文档(pip install -h)，使用选项-q一次使您摆脱警告消息，两次也使您摆脱错误级别，三次也使您摆脱临界级别消息。

如果您想将警告保存在文件中，以备以后需要阅读它们，而不希望它们出现在您的终端中，您可以使用:

pip install --upgrade pip 2> nameOfYourLog.File

我真笨，我没注意到你在用Windows。如果您没有使用cygwin或类似unix的东西，那么命令pip install --upgrade pip 2> nameOfYourLog.File将不适合您，但是根据在线文档，pip install -q --upgrade应该仍然可以完成它的工作。
