python - 导入错误 : No module named 'Crypto' on Mac (Pycrypto is up-to-date)

Question

Pycrypto 已正确安装(至少据我所知。一切都是最新的，我已尝试卸载并使用 pip 重新安装)。我不确定这里有什么问题，但这段代码可以在其他人的计算机上运行，​​所以它必须专门针对我的配置。任何帮助将不胜感激!

Answer 1

有一个名为“crypto”的模块导致了这个问题。至少对我来说，在 Mac OS 中。有两个包名“crypto”和“Crypto”导致了这个冲突。

由于您使用的是 Python 3.4，请尝试运行以下命令进行卸载:

sudo pip3 uninstall crypto
sudo pip3 uninstall pycrypto

然后使用以下命令再次安装 pycrypto 模块:

sudo pip3 install pycrypto

这应该可以解决问题。
