Python:我在运行 Python Unittest 时遇到错误

Question

我正在使用以下 python 版本

$ python --version
Python 3.8.0

Python文件夹只包含以下4个

IDLE (Python 3.8 32-bit)
Python 3.8 (32-bit)
Python 3.8 Manuals (32-bit)
Python 3.8 Module Docs (32-bit)

我在 test_sum_unittest.py 中有以下单元测试

import unittest


class TestSum(unittest.TestCase):

    def test_sum(self):
        self.assertEqual(sum([1, 2, 3]), 6, "Should be 6")

    def test_sum_tuple(self):
        self.assertEqual(sum((1, 2, 2)), 6, "Should be 6")

if __name__ == '__main__':
    unittest.main()

运行测试

python test_sum_unittest.py

错误日志如下

Traceback (most recent call last):
  File "test_sum_unittest.py", line 1, in <module>
    import unittest
  File "C:\Users\ali\AppData\Local\Programs\Python\Python38-32\lib\unittest\__init__.py", line 59, in <module>
    from .result import TestResult

    from token import *
  File "C:\Users\ali\Flasky\Automation\token.py", line 1, in <module>
    import requests
ModuleNotFoundError: No module named 'requests'

哪里出了问题？

任何帮助将不胜感激，我有较早的 python2.7，我可以在 tht 文件夹中看到我有很多文件夹，即 libs、脚本、Lib、Doc、Dll、tcl、工具，但在 python 3.8.0 中是这样的

现在更新，我已经安装了 python 3.5，但仍然出现以下错误

好的，现在我已经重新安装了 python 3-5-1，文件夹似乎包含了所有内容，但仍然出现以下错误
