python NameError:全局名称'__file__'未定义 [英] python NameError: global name '__file__' is not defined

问题描述

当我在python 2.7中运行此代码时，出现此错误:

When I run this code in python 2.7, I get this error:

Traceback (most recent call last):
File "C:\Python26\Lib\site-packages\pyutilib.subprocess-3.5.4\setup.py", line 30, in <module>
    long_description = read('README.txt'),
  File "C:\Python26\Lib\site-packages\pyutilib.subprocess-3.5.4\setup.py", line 19, in read
    return open(os.path.join(os.path.dirname(__file__), *rnames)).read()
NameError: global name '__file__' is not defined

代码是:

import os
from setuptools import setup


def read(*rnames):
    return open(os.path.join(os.path.dirname(__file__), *rnames)).read()


setup(name="pyutilib.subprocess",
    version='3.5.4',
    maintainer='William E. Hart',
    maintainer_email='[e-mail]',
    url = 'https://software.sandia.gov/svn/public/pyutilib/pyutilib.subprocess',
    license = 'BSD',
    platforms = ["any"],
    description = 'PyUtilib utilites for managing subprocesses.',
    long_description = read('README.txt'),

推荐答案

当您在python交互式shell中将此行os.path.join(os.path.dirname(__file__))附加到该错误时，就会发生此错误.

This error comes when you append this line os.path.join(os.path.dirname(__file__)) in python interactive shell.

Python Shell未检测到__file__中的当前文件路径，并且与您在其中添加此行的filepath有关

Python Shell doesn't detect current file path in __file__ and it's related to your filepath in which you added this line

因此，您应该在file.py中写此行os.path.join(os.path.dirname(__file__)).然后运行python file.py，它可以工作，因为它需要您的文件路径.

So you should write this line os.path.join(os.path.dirname(__file__)) in file.py. and then run python file.py, It works because it takes your filepath.
