我用virtualenv env
创建了一个virtualenv,然后(在采购env/bin/activate
之后)用pusher
安装了pip
。但是,每当我尝试运行模块时,都会出现此错误:
Traceback (most recent call last):

ImportError: cannot import name certificate_transparency
所有依赖项均已正确安装,并且ls env/lib/python2.7/site-packages/cryptography/x509
显示(以及其他)certificate_transparency.pyc
(和.py
)。
我没有意识到安装pusher
的其他方法吗?
答案 0 :(得分:0)
所以,这不能解释问题,但可以解决。
我使用了错误的后端。导入pusher.gae
并设置backend=pusher.gae.GAEBackend
解决了这个问题。
