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
根据此好的,请转到" https://pypi.org/simple/pip/ ",然后下载最新的.whl文件(滚动到底部).拥有它后,在同一文件夹中打开cmd(通过在文件资源管理器中单击File-> open 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
,文件名是您下载的文件的名称(应为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,告诉我是否可行.
Try that and tell me if it works.
