"参数1有出乎意料的类型" str "

I'm trying to use PyKDE, PyKDE.kdecore.KStandardDirs to be precise. This method is called with two strings according to the documentation and according to the PyQt4 documentation, I can use standard Python strs instead of QString. This doesn't work:

我试着用PyKDE, PyKDE.kdecore。KStandardDirs精确。这个方法是根据文档和PyQt4文档的两个字符串来调用的，我可以使用标准的Python strs而不是QString。这并不工作:

>> KStandardDirs.locate()("socket", "foo")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: KStandardDirs.locate(): not enough arguments
>>> KStandardDirs.locate("socket", "foo")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: KStandardDirs.locate(): argument 1 has unexpected type 'str'

I can't use QString either because it doesn't seem to exist:

我不能使用QString，因为它似乎不存在:

>>> from PyQt4.QtCore import QString
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: cannot import name QString
>>> from PyQt4.QtCore import *
>>> QString
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'QString' is not defined

What am I doing wrong?

我做错了什么?

I suspect that PyKDE is not yet Python 3 ready, at least as far as that error message is concerned; try passing in a bytestring instead:

我怀疑PyKDE还没有准备好Python 3，至少就那个错误消息而言是这样的;试着通过一个bytestring:

KStandardDirs.locate(b"socket", "foo")
