Question

我正在尝试运行过去能够运行的脚本。它因错误而停止：

ModuleNotFoundError: No module named 'cryptography.hazmat.bindings._constant_time'

我最近删除了python 3.6并安装了python ActiveState：

ActivePython 3.6.0.3600 (ActiveState Software Inc.) based on
Python 3.6.0 (default, Jan 23 2017, 20:01:14) [MSC v.1900 64 bit (AMD64)] on win32

到目前为止我尝试过的事情：

看起来今天发布的版本实际上有问题；使用cryptography==2.5可能会使您克服该错误，直到他们修复2.6。
