argparse模块在Python中不起作用 [英] argparse module not working in Python

问题描述

我正在尝试使argparse模块在Python中工作.我的问题是，在全新安装中，我得到以下信息:

I'm trying to get the argparse module working in Python. My problem is that on a fresh install, I get the following:

File "test.py", line 3, in <module>
import argparse
File "/home/jon/Pythons/realmine/argparse.py", line 3, in <module>
parser = argparse.ArgumentParser(description='Short sample app')
AttributeError: 'module' object has no attribute 'ArgumentParser'

test.py是:

import argparse

很明显，我缺少了一些东西.有人可以帮忙吗?

Clearly, I'm missing something. Can anyone help?

推荐答案

通常，此症状是用您自己的一个遮盖内置模块的结果.并从错误消息:

Usually this symptom is the result of shadowing a builtin module with one of your own. And from the error message:

File "/home/jon/Pythons/realmine/argparse.py", line 3, in <module>

您似乎拥有自己的模块argparse.py，这引起了问题，因为它是test.py试图导入的模块，并且缺少ArgumentParser.将您的argparse.py重命名为其他名称(并删除所有.py [c/o]文件).

it looks like you have your own module argparse.py, which is causing the problem, because it's the one which test.py is trying to import, and which lacks ArgumentParser. Rename your argparse.py to something else (and remove any .py[c/o] files).
