无法升级 pip 和请求模块

Question

我无法将pip 从默认的venv 版本20.0.2 升级到最新版本的pip 20.2。

我使用 Python 3.8.5 尝试过以下操作：

$ python3 -m venv venv
$ source venv/bin/activate // in the venv now
$ pip install -U pip

我得到以下堆栈跟踪：

TypeError: __init__() got an unexpected keyword argument 'filter_status'

当我尝试运行 $ pip install requests 时也会发生同样的事情。

任何人有任何想法可能是什么问题？

Answer 1

似乎 pip 在我的缓存中遇到了问题

运行这个工作（例如）：

$ pip install requests --no-cache-dir
