我有一个代码，允许用户从所需的路径文件夹中选择并在QlistWidget中显示现有的docx文件。
问题在于，当用户选择文件时，系统必须返回文件的完整路径。而是显示以下错误：
builtins.TypeError：预期的str，字节或os.PathLike对象，而不是 Builtin_function_or_method
我知道此行中的 FileListSelected函数中存在错误：
p = pathlib.Path(self.fullPath.index)
但不知道如何解决。
示例，这是CheckPath打印的结果：

答案 0 :(得分：0)
问题可能是您在函数“ setExistingDirectory”中返回了某些内容，然后启动了 elif 而不是if。因此，不应到达第一个“返回文件夹”之后的代码。如果达到目标，它将引发异常。
这意味着，fullPath从未被公开。
def setExistingDirectory(self): # create a pop up fileDirectory Dialog Message in order to select the desired folder.
self.fileList=[]
dialog = QDialog()
options = QFileDialog.DontResolveSymlinks | QFileDialog.ShowDirsOnly
Folder = QFileDialog.getExistingDirectory(dialog, "Open Folder" ,options=options)
return Folder
elif self.rdBtn_docx.isChecked() and filename.endswith("docx") or filename.endswith("doc") :
self.fullPath=os.path.join(root,filename)
答案 1 :(得分：0)
看起来好像self.fullPath已经是一个字符串，因为您正在这样做：
self.fullPath=os.path.join(root,filename)
返回一个字符串。
因此，当您执行self.fullPath.index时，您将调用str的索引属性，该属性是一个内置函数，即builtins.TypeError: expected str, bytes or os.PathLike object, not builtin_function_or_method。
我最好的猜测是检查self.fullPath的所有出现情况，以查看它是否始终是应该的对象。
