在命令提示符中执行以下命令，

C:\Users\Owner\AppData\Local\Programs\Python\Python310>python -m pip install --upgrade pip

当偏离主题时，人们可能会想到这个问题，希望更新pip本身(参见这里)。

要为Python3.4+升级pip，必须按如下方式使用pip3:

sudo pip3 install pip --upgrade

这将升级位于:/usr/local/lib/python3.的pipX / dist-packages

否则，要为Python2.7升级pip，您可以如下所示使用pip:

sudo pip install pip --upgrade

这将升级位于:/usr/local/lib/python2.7/dist-packages的pip

我使用下面的行来更新我所有过期的包:

pip list --outdated --format=freeze | awk -F '==' '{print $1}' | xargs -n1 pip install -U

此外，在Jupyter笔记本中，通过在代码单元中运行下面的代码，您可以更新您的包:

%pip install <package_name> --upgrade

在终端中使用此代码:

python -m pip install --upgrade PACKAGE_NAME

例如，我想更新pip包:

python -m pip install --upgrade pip

更多的例子:

python -m pip install --upgrade selenium
python -m pip install --upgrade requests
