Question

在Python2.7和PySide下，我能够指向〜/ .config /的子目录。但是，当我转移到Python3和PyQt5时，我可以打开〜/ .config /但不能打开它的子目录...（所有目录都有drwxr-xr-x权限，没有特殊的聊天内容或ACL发生的事情。）

#!/usr/bin/env python3
# -*- coding: utf-8 -*-

# Arch Linux (up-to-date)
# Python 3.6.5
# python-pyqt5 5.10.1-3

import os
import sys
from   PyQt5.QtCore    import *
from   PyQt5.QtGui     import *
from   PyQt5.QtWidgets import *

app = QApplication(sys.argv)

# Succeeds. (Lists three files in the autostart directory.)
wd = os.path.expanduser("~/.config/autostart")
os.system("ls {0}".format(wd))

# Fails. Opens to ~/
x = QFileDialog.getExistingDirectory(caption="Choose presets...", directory=wd)

wd = os.path.expanduser("~/.config")

# Succeeds. Opens at ~/.config/
x = QFileDialog.getExistingDirectory(caption="Choose presets...", directory=wd)

# Succeeds. Opens at ~/Documents/Volunteer
wd = os.path.expanduser("~/Documents/Volunteer")
x = QFileDialog.getExistingDirectory(None, "Choose presets...", wd)

而且，感谢@ekhumoro我们有一个胜利者！告诉QFileDialog不使用本机对话框就可以了。具体做法是：

#!/usr/bin/evn python3
# -*- coding: utf-8 -*-

# Arch Linux (up-to-date)
# Python 3.6.5
# python-pyqt5 5.10.1-3

import os
import sys
from   PyQt5.QtCore    import *
from   PyQt5.QtGui     import *
from   PyQt5.QtWidgets import *

app = QApplication(sys.argv)

# Succeeds. (Lists three files in the autostart directory.)
wd = os.path.expanduser("~/.config/autostart")
os.system("ls {0}".format(wd))

# SUCCEEDS (where it previously failed)
x = QFileDialog.getExistingDirectory(caption="Choose presets...", directory=wd,
                                     options=QFileDialog.DontUseNativeDialog)

为什么PyQt5 QFileDialog.getExistingDirectory无法看到〜/ .config /子目录？
