Question

我开始学习python，我使用pycharm，mac，并且尝试导入mate扩展包。.我在python文件的开头添加了这一行："from mate import *"，但它不起作用，我尝试安装mate软件包，每次执行此操作都会收到此错误，我也将此行放在终端"python setup.py install"中，但找不到setup.py ... 需要一些帮助，谢谢:)

Answer 1

尝试使用pip安装依赖项。

mate位于PyPi存储库（link）上，因此您可以使用pip install mate

安装它

Answer 2

我找到了解决方案，看来是需要我下载一个错过的软件包“ vcversioner”。 https://pypi.org/project/vcversioner/ 没有这个软件包，我无法将新软件包下载到pycharm 我用这条推荐线下载了vcversioner-> pip install vcversioner 并解决了问题

命令“ python setup.py egg_info”失败，找不到setup.py
