PyCharm 调试器不起作用

Question

我刚刚下载了 PyCharm 社区版，每次尝试在 PyCharm 中调试任何 Python 程序时，都会收到此错误：

C:\Python31\python.exe "C:\Program Files (x86)\JetBrains\PyCharm Community 
Edition 2016.1\helpers\pydev\pydevd.py" --multiproc --qt-support --client 127.0.0.1 --port 59207 --file C:/Users/Gal/PycharmProjects/untitled/test.py
pydev debugger: process 5388 is connecting

Connected to pydev debugger (build 145.260)
Traceback (most recent call last):
  File "C:\Program Files (x86)\JetBrains\PyCharm Community Edition 2016.1\helpers\pydev\pydevd.py", line 1530, in <module>
    globals = debugger.run(setup['file'], None, None, is_module)
  File "C:\Program Files (x86)\JetBrains\PyCharm Community Edition 2016.1\helpers\pydev\pydevd.py", line 937, in run
    pydev_imports.execfile(file, globals, locals)  # execute the script
  File "C:\Program Files (x86)\JetBrains\PyCharm Community Edition 2016.1\helpers\pydev\_pydev_imps\_pydev_execfile.py", line 11, in execfile
    stream = tokenize.open(file)  # @UndefinedVariable
AttributeError: 'module' object has no attribute 'open'

并打开一个名为“_pydec_excecfile.py”的 python 文件：

#We must redefine it in Py3k if it's not already there
def execfile(file, glob=None, loc=None):
    if glob is None:
        import sys
        glob = sys._getframe().f_back.f_globals
    if loc is None:
        loc = glob
# It seems that the best way is using tokenize.open(): http://code.activestate.com/lists/python-dev/131251/
import tokenize
stream = tokenize.open(file)  # @UndefinedVariable
try:
    contents = stream.read()
finally:
    stream.close()

#execute the script (note: it's important to compile first to have the filename set in debug mode)
exec(compile(contents+"\n", file, 'exec'), glob, loc)

我该如何修复它？

Answer 1

我在一个名为“tokenizer.py”的文件的项目中遇到了类似的情况。当尝试在同一项目中（甚至在不同的文件中）调试不同的 Python 代码时，我得到以下错误输出：

Traceback (most recent call last):

File "C:\Programs\PyCharm\plugins\python-ce\helpers\pydev\pydevd.py", line 1483, in _exec 

pydev_imports.execfile(file, globals, locals)  # execute the script
File "C:\Programs\PyCharm\plugins\python-ce\helpers\pydev\_pydev_imps  \_pydev_execfile.py", line 11, in execfile 
stream = tokenize.open(file)  # @UndefinedVariable 

AttributeError: module 'tokenize' has no attribute 'open'

我可以运行代码，但不能调试它。然后我在链接中找到了一个讨论，其中的想法是代码中的模块隐藏了调试器所需的一些顶级包。我重命名了“tokenizer”模块，并且可以再次进行调试。这似乎是秘诀：尝试重命名错误输出中提到的模块。
