有什么问题?我尝试了python -m pip install -U pip"和python -m pip install --upgrade pip"都出现了相同的错误(和pip安装 -U --force-reinstall pip").我该怎么办?

You are using pip version 9.0.3, however version 18.0 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

推荐答案

尝试使用easy_install -U pip，根据这个错误报告.

好的，转到https://pypi.org/simple/pip/"，然后下载最新的 .whl 文件(滚动到底部).获得后，在同一文件夹中打开 cmd(通过在文件资源管理器中单击文件"->打开 powershell/cmd")，然后键入

Okay, go to "https://pypi.org/simple/pip/", and download the latest .whl file (scroll to the bottom). When you have it, open cmd in the same folder (by clicking File -> open powershell/cmd in the file explorer), and type

pip install filename，filename 是你下载的文件名(应该是 pip-18.0-py2.py3-none-any.whl).

pip install filename, with filename being the name of the file you downloaded (Should be pip-18.0-py2.py3-none-any.whl).

尝试一下，然后告诉我它是否有效.

Try that and tell me if it works.
