Question

在Windows 7 / Python 3.2.5（pip install pylint）下安装Pylint 1.5.4后，尝试调用时出现以下异常：

b:\Sandbox\PyLoad>pylint PyLoad.py
Traceback (most recent call last):
  File "c:\python32\lib\site-packages\astroid\builder.py", line 172, in _data_build
    node = _parse(data + '\n')
  File "c:\python32\lib\site-packages\astroid\builder.py", line 40, in _parse
    return compile(string, "<string>", 'exec', _ast.PyCF_ONLY_AST)
  File "<string>", line 12
    return u''
             ^
SyntaxError: invalid syntax

During handling of the above exception, another exception occurred:

    fake = AstroidBuilder(MANAGER).string_build(code)['whatever']
  File "c:\python32\lib\site-packages\astroid\builder.py", line 146, in string_build
    module = self._data_build(data, modname, path)
  File "c:\python32\lib\site-packages\astroid\builder.py", line 174, in _data_build
    raise exceptions.AstroidBuildingException(exc)
astroid.exceptions.AstroidBuildingException: invalid syntax (<string>, line 12)

看起来有些东西试图使用Python 2语法返回一个unicode字符串，但这是Python 3。

在astroid的builder.py中，使用字符串调用_data_build：

class whatever(object):
    def join(self, iterable):
        return b''
    def replace(self, old, new, count=None):
        return b''
    def format(self, *args, **kwargs):
        return b''
    def encode(self, encoding='ascii', errors=None):
        return ''
    def decode(self, encoding='ascii', errors=None):
        return u''
           .
           .
           .

我认为 return u''导致问题。

有人看过这个，并有解决方案吗？
