python3.8 virtualenv pip无法升级 [英] python3.8 virtualenv pip not upgrading

问题描述

在运行以下命令时

pip install --upgrade pip

即使我无法安装任何其他软件包，它也会显示以下错误，因为它说先升级pip.

it shows following error even I can't install any other packages as it says upgrade pip first.

如果我跑步

pip list

我有以下包裹

Package    Version
---------- -------
pip        19.3.1 
setuptools 42.0.2 
wheel      0.33.6 

推荐答案

问题不在于pip的版本，而在于ssl.您安装的python版本没有ssl模块，如果您在未安装libssl-dev标头的情况下编译python，则可能会出现ssl模块. (或者您下载的版本是这样制作的.)

The problem is not with pip's version, but with ssl. The version of python you installed does not have the ssl module, which can occur if you compiled python without installing the libssl-dev headers. (Or the version you downloaded was made so).
