无法在 Python3.6 上安装枚举包

Question

我正在尝试运行 this example 在 MacOS High Sierra 上。需要安装page包，需要安装pytodos包，需要安装enum包，安装失败。

$ python3 page_object_test_case.py 
Traceback (most recent call last):
  File "page_object_test_case.py", line 3, in <module>
    import page
ModuleNotFoundError: No module named 'page'
$ pip3 install page
...
Successfully installed click-6.7 page-1.0.16
$ python3 page_object_test_case.py 
Traceback (most recent call last):
  File "page_object_test_case.py", line 3, in <module>
    import page
  File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/page/__init__.py", line 2, in <module>
    from pytodos import todo
ModuleNotFoundError: No module named 'pytodos'
$ pip3 install pytodos
Collecting pytodos

    Complete output from command python setup.py egg_info:

        version = main_module.__version__
    AttributeError: module 'enum' has no attribute '__version__'

请注意，我已尝试在 Ubuntu 上执行相同的操作。我不得不重复每一步。但是，安装 enum 失败并出现以下错误：

AttributeError: module 'enum' has no attribute 'IntFlag'

我做错了什么？

Answer 1

您在 pip install page 处出错了。

您应该提供自己的模块 page.py，如 here 所述。

pip install page 拉了一些 garbage and unrelated/unmaintained projects from PyPI.
