问题重现

引用ssl报错ModuleNotFoundError: No module named ‘_ssl’

>>> import ssl
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "D:\Anaconda\lib\ssl.py", line 98, in <module>
    import _ssl             # if we can't import it, let the error propagate
ModuleNotFoundError: No module named '_ssl'
>>>

同时对pip安装东西也造成了影响

C:\Users\YUZI>pip install jieba
pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
Collecting jieba

解决方案

我也搜了不少东西，但大多数都是在Linux上的解决办法。
在Windows上其实更简单。只要替换 _ssl.pyd 这个文件就行
anaconda的目录为 D:\Anaconda\DLLs\_ssl.pyd
在Python的官网中下载相对应的版本的Python ZIP文件。
例如：
查询本机使用的Python版本
去官网找到相对应的下载页面，这里使用的是Python3.7.2并下载ZIP包
下载完成后解压，并找到我们需要的文件

复制并替换到Anaconda中，我的目录为 D:\Anaconda\DLLs\_ssl.pyd并测试import与pip

成功！！
