如何修复 ModuleNotFoundError: No module named 'dateutil'

问题：

你想在 Python 中使用 dateutil 库，但当你尝试导入它时，你看到类似这样的异常：

error_message.txt

Traceback (most recent call last):
  File "my.py", line 11, in <module>
    import dateutil as dl
ModuleNotFoundError: No module named 'dateutil'

Traceback (most recent call last):
  File "my.py", line 11, in <module>
    import dateutil as dl
ModuleNotFoundError: No module named 'dateutil'

当你尝试使用例如 pip install dateutil 安装它时，你看到此错误消息：

error_message.txt

Collecting dateutil
  Could not find a version that satisfies the requirement dateutil (from versions: )
No matching distribution found for dateutil

Collecting dateutil

pip install python-dateutil
