python - 无法在 Python 中导入 Flask

Question

我是 python 新手。我正在尝试将 Flask 导入 python 脚本。但它抛出了一个错误。
这是我的 python 脚本“ tokenize.py ”

from flask import Flask, Response

但是运行它时出现以下错误：

$ python2.7 tokenize.py

Traceback (most recent call last):
  File "tokenize.py", line 4, in <module>
    from flask import Flask, Response  
  File "/Library/Python/2.7/site-packages/flask/__init__.py", line 17, in <module>
    from werkzeug.exceptions import abort
  File "/Library/Python/2.7/site-packages/werkzeug/__init__.py", line 151, in <module>
    __import__('werkzeug.exceptions')
  File "/Library/Python/2.7/site-packages/werkzeug/exceptions.py", line 67, in <module>
    from werkzeug._internal import _get_environ
  File "/Library/Python/2.7/site-packages/werkzeug/_internal.py", line 13, in <module>
    import inspect
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/inspect.py", line 39, in <module>
    import tokenize
  File "/Users/abashir/tokenize.py", line 4, in <module>
    from flask import Flask, Response  
ImportError: cannot import name Flask

我正在使用MacOS High Sierra 版本 10.13.6 (17G6S)。

$ python2.7 -V
Python 2.7.10

在点子列表中：

$ pip list
Package                                Version 
-------------------------------------- --------
...
Flask                                  1.0.2
...

当我尝试重新安装 Flask

$ pip install Flask
Requirement already satisfied: Flask in /Library/Python/2.7/site-packages (1.0.2)
Requirement already satisfied: Jinja2>=2.10 in /Library/Python/2.7/site-packages (from Flask) (2.10)
Requirement already satisfied: itsdangerous>=0.24 in /Library/Python/2.7/site-packages (from Flask) (1.1.0)
Requirement already satisfied: Werkzeug>=0.14 in /Library/Python/2.7/site-packages (from Flask) (0.14.1)
Requirement already satisfied: click>=5.1 in /Library/Python/2.7/site-packages (from Flask) (7.0)
Requirement already satisfied: MarkupSafe>=0.23 in /Library/Python/2.7/site-packages (from Jinja2>=2.10->Flask) (1.1.0)

问题是什么？以及如何解决？
