为我工作。

pkg install openssl

使用此选项可以启用ssl。

这招对我很管用:

yum install python36-pyOpenSSL 

Python版本和包管理器可能不同。

目前在Windows 10上的Anaconda提示符(Anaconda3)也有同样的问题。这里是解决方案:https://github.com/ContinuumIO/anaconda-issues/issues/10576

为我工作。

sudo apt-get install libssl-dev

使用此选项为pip启用ssl。 如果有人遇到问题请告诉我。

我也有同样的问题，这是因为我改变了环境的文件夹。 我只是移除了env，重新安装了所有东西。

我得到了同样的错误:

WARNING: pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError("Can't connect to HTTPS URL because the SSL module is not available.")': /simple/pb-tool/

在《Anaconda》中，我使用了以下命令:

conda install anaconda-navigator

本文中提到:pip配置了需要TLS/SSL的位置，但是Python中的SSL模块不可用
