只要尝试通过Anaconda提示安装即可

如果您已经通过scoop安装了anaconda，并且在conda环境中使用pip时遇到此错误，您可以通过…

将这些添加到路径中

C:\Users\YOUR_USERNAME\scoop\apps\anaconda3\current
C:\Users\YOUR_USERNAME\scoop\apps\anaconda3\current\Scripts
C:\Users\YOUR_USERNAME\scoop\apps\anaconda3\current\Library
C:\Users\YOUR_USERNAME\scoop\apps\anaconda3\current\Library\bin

通过scoop安装openssl

scoop install openssl

并从..复制以下dll。\anaconda3\Library\bin到..\anaconda3\ dll

操作系统一样,pyenv

如果你的python是pyenv安装的，其中pyenv是在macOS上安装的，可能有一个更新的版本可以修复这个问题:

$ brew update && brew upgrade pyenv

然后重新安装python版本:

$ pyenv install 3.7.2
pyenv: /Users/luckydonald/.pyenv/versions/3.7.2 already exists
continue with installation? (y/N) 

注意，像这样覆盖现有的python安装有点脏，但在我的例子中，它确实有效。可能更干净的方法是删除它，然后正确地重新创建。

问题可能来自您安装的openssl包版本。这就是我的情况，我解决了这个问题，只是升级它。我在Mac OS上，使用brew:

brew upgrade openssl

如果你用brew安装了python，这应该会直接修复这个问题，因为python依赖于openssl

如果有人使用Arch Linux操作系统，我通过运行这个解决了TLS/SSL问题:

sudo pacman -S openssl

然后我可以使用pip来安装我需要的包:

pip install openpyxl

我得到了同样的错误:

在《Anaconda》中，我使用了以下命令:

conda install anaconda-navigator
