NameError: name 'N_TOKENS' 未定义 [英] NameError: name 'N_TOKENS' is not defined

问题描述

我是 Python 新手，刚开始为 Windows 安装 PyCharm.从 Skype 下载了一些示例代码以测试他们的 SkypeKit API.但是...一旦我点击调试按钮，我就会得到这个:(我安装了 Python 2.7 和 Django 1.4)

I am new on Python and just got around to install PyCharm for Windows. Downloaded some sample code from Skype for testing their SkypeKit API. But... As soon as I hit the debug button, I get this: (I have Python 2.7 and Django 1.4 installed)

Traceback (most recent call last):
  File "C:\Program Files (x86)\JetBrains\PyCharm 2.0.2\helpers\pydev\pydevd.py", line 2, in <module>
    from django_debug import DjangoLineBreakpoint
  File "C:\Program Files (x86)\JetBrains\PyCharm 2.0.2\helpers\pydev\django_debug.py", line 1, in <module>
    import inspect
  File "C:\Program Files (x86)\Python27\lib\inspect.py", line 39, in <module>
    import tokenize
  File "C:\Program Files (x86)\Python27\lib\tokenize.py", line 38, in <module>
    COMMENT = N_TOKENS
NameError: name 'N_TOKENS' is not defined

Process finished with exit code 1

这是什么意思，我可以做些什么来解决它?

What does this mean and what can I do to fix it?

推荐答案

tokenize.py 模块可能加载了错误的 token.py 模块.请参阅导入 numpy 时出错.解决方案 1) 重命名新的 token.py (token2.py) 并在 tokenize.py 等中更新对它的引用. 解决方案 2) 如果新的 token.py 在 python 包中，您可以消除导入语句的歧义:

The tokenize.py module is probably loading the wrong token.py module. See error importing numpy. Solution 1) rename the new token.py (token2.py) and update references to it in tokenize.py etc. Solution 2) if the new token.py is in a python package you can disambiguate the import statement:

import CorrectPythonPackage.token as token2

#or 

from CorrectPythonPackage.token import *

其中 CorrectPythonPackage 是包含 token.py 文件的文件夹名称.

Where CorrectPythonPackage is the folder name containing the token.py file.
