Question

我在使用请求库时遇到问题。我使用pip来安装它，我也通过github安装，安装就好了。但是当我尝试导入lib时，我收到了这个错误：

我在另一篇帖子中看到一个人讲了一些关于PATH的内容，但我不明白......与/ usr / bin和/ usr / local / bin之间的冲突有关。我不知道这是否与它有关。我也使用pip2.7来安装lib，它显示在pip list命令中。我很感激任何帮助。

问题出在加密模块中。它也可以在github page找到。解决方案似乎是您需要替换枚举包：

pip uninstall enum
pip install enum34

请注意，如果您使用sudo pip

中的软件包，则需要使用/usr/
