克服SSL:使用URLLIB3时在Windows 10上在Windows 10上进行了证书

Question

python中的此简单代码显示ASCII ART，并取自以下Quora响应：https：//qr.ae/twnb4s。我通过python.org以及Anaconda Suite在Windows 10笔记本电脑上安装了Python版本3.7.3。该代码在通过Anaconda启动的Jupyter笔记本上运行良好。但是，当我通过Pycharm IDE运行相同的代码时，我会得到SSL相关的错误。

我在线搜索了此错误，但找不到在Windows 10 Python 3.7.3安装上解决此问题的方法。但是它在我的Anaconda Python 3.7.3版本上正常工作。那么是否可以克服此错误？代码：

import ascii
output =  ascii.loadFromUrl("https://i.dailymail.co.uk/i/pix/2015/09/01/18/2BE1F43200000578-0-image-a-17_1441127603656.jpg")
print(output)

通过Pycharm IDE运行上述代码时的错误：

Answer 1

如果您还没有，可以尝试从PIP安装celectifi软件包。否则，这里有许多解决方案，其中一些解决方案涵盖了如何确保您已安装证书，而其他则显示如何禁用证书验证。
