Question

我正在使用Anaconda环境进行python。我使用Anaconda Navigator安装了paramiko（v.2.0.2）和cryptography（v 1.5）模块。当我尝试执行此import语句时：进口netmiko 我收到一条错误消息“ImportError：没有名为cryptography.hazmat.backends的模块”

cmd窗口中的总输出为：

>>> import netmiko
    Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
    File "build\bdist.win-amd64\egg\netmiko\__init__.py", line 1, in <module>

    File "build\bdist.win-amd64\egg\paramiko\transport.py", line 32, in <module>
ImportError: No module named cryptography.hazmat.backends

有谁知道如何解决这个问题？任何帮助表示赞赏。

Answer 1

我猜命令的正确顺序是：

#apt-get update
#apt-get install python-dev
#apt-get install libffi-dev
#pip install cryptography

它在我的案例中解决了这个问题

Answer 2

您可能遇到问题，因为您没有安装libffi-dev。安装＆＃34; python-dev＆＃34;和＆＃34; libffi-dev＆＃34;在OS层可能有帮助。

ImportError：在Windows上没有名为cryptography.hazmat.backends的模块 - anaconda
