问题是什么?我尝试了“python -m pip install -U pip”和“python -m pip install --upgrade pip”都出现了同样的错误(和“pip安装 -U --force-reinstall pip").我该怎么办?

AttributeError: 'NoneType' object has no attribute 'bytes'
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.
最佳答案
尝试使用 easy_install -U pip
,根据 bug report .
编辑:好的,转到“https://pypi.org/simple/pip/”,并下载最新的 .whl 文件(滚动到底部)。有了它后,在同一文件夹中打开 cmd(通过单击文件 -> 在文件资源管理器中打开 powershell/cmd),然后键入
pip install filename
,其中 filename 是您下载的文件的名称(应为 pip-18.0-py2.py3-none-any.whl
)。
试一试,告诉我它是否有效。
