莫名其妙的问题

 

我在写爬虫时，上一刻还用着requests，但是下一刻它就报了如下错误，我一开始以为是我网络问题，但我检查一下，我能正常上网，就把这个给过滤了，且在 Pycharm中导包并无错误。于是，我开始在网上找资料但是仍然没有找到答案。后来，我就重新下载Python3.6.6了，不想折腾。等我去做其它事回来，差点就重新安装了，但我又不甘心，于是又在终端输入了如下命令。 于是还是报同样的错:

>> import requests

Traceback (most recent call last):

File "<stdin>", line 1, in <module>

File "E:\Python36\lib\site-packages\requests\__init__.py", line 95, in <module>

from cryptography.hazmat.bindings.openssl.binding import Binding

if not getattr(lib, condition):

AttributeError: cffi library '_openssl' has no function, constant or global variable named 'Cryptography_HAS_CMS'

于是，我就在想，找问题时，我们往往是从最下面找，那么解决这个问题，我能不能从上面找呢。

尝试了一下：

果然这导包是没问题了：

再次去获取数据 ：

可以看到，成功了，我再回到我的Pycharm中再去验证一下：
