Question

问题：
当我单击运行的按钮时，我的python gui（tkinter）被冻结：
filename = filedialog.askdirectory()
当我在另一个脚本中使用from pywinauto import application时，只会发生。如果我注释掉pywinauto导入，askdirectory可以正常工作。没有冻结，窗口将按预期方式弹出。发生这种情况时，我看不到任何错误。

很抱歉，长期以来，我想提供尽可能多的细节。让我知道是否需要更多以及您正在寻找什么。理想情况下，我想使用askdirectory，但是我认为我可以只使用askopenfilename来获取该目录。

Python版本：
Python 3.4.4

Windows版本：
Windows Server 2012 R2（无法更改）

我尝试过的事情：
1.通过教程进行基本线程处理（每次仍然冻结，底部的代码示例）
2.注释掉部分代码以缩小问题范围。
3.尝试通过PyCharms调试器进行调试，但是如果出现错误，则看不到它。
4.不同的IDE。

IDLE =失败

Pycharm =失败（据我所知，解释器与空闲状态相同，因此不足为奇）

Pythonwin =很好用）

以下代码块：
如果您愿意的话，我将这些代码块按照它们之间的交互顺序放在下面。它从第一个开始，然后到第二个（中间），最后到第三个。

问题：
我有办法检查错误吗？我在这里做错了什么导致这种情况发生吗？为什么askopenfilename可以正常工作，而不是askdirectory？

包含冻结窗口的文件：

from InstallMenu import MainMenu
from tkinter import *
from tkinter import filedialog

"""
This is where it freezes.  If I change askdirectory to openaskfilename it 
works without any issues.  If I comment out the from pywinauto import 
application from opusite.py, askdirectory works without issue.
"""
def chooseInstallFolder(installFolderPath):
    filename = filedialog.askdirectory()
    installFolderPath.config(text=filename)

def submitFolder(installFolderApp, installFolderPath, setObj):
    installFolderApp.destroy()
    MainMenu(installFolderPath, setObj)

def chooseInstall(setObj):
    installFolderApp = Tk()
    installFolderApp.title("Find Install Folder")
    installFolderApp.geometry("300x200")

    #Gui items
    pickAFolder = Label(installFolderApp, text = "Select your Install Folder")
    pickInstallerButton = Button(installFolderApp, text="Browse", command = lambda : chooseInstallFolder(installFolderPath))
    installFolderPath = Label(installFolderApp, text = " ")
    submit = Button(installFolderApp, text="Submit", command = lambda : submitFolder(installFolderApp, installFolderPath, setObj))

    #Packing
    pickAFolder.pack()
    installFolderPath.pack()
    pickInstallerButton.pack()
    submit.pack()

    installFolderApp.mainloop()

上面的“提交”按钮的菜单脚本进入：
我已经注释掉iParcPro，因为它使用了导致冻结的相同导入。

import opusite
#from iParcPro import *
from Sql import *
from tkinter import *

def OPUSiteInstall(installFolderPath):
    opusite.OPUSiteInstall(installFolderPath, setObj)
    opusite.rs485Install(installFolderPath, setObj)

def MainMenu(installFolderPath, setObj):
    menuWindow = Tk()
    menuWindow.title("Auto Installer Menu")
    menuWindow.geometry("325x250")

    #Create variables
    ChooseAButton = Label(menuWindow, text = "Choose an option")

    OPUSiteButton = Button(menuWindow, text="OPUSite Install", height = 1, 
    width 
    = 15, command = lambda : OPUSiteInstall(installFolderPath, setObj))

    #Pack
    ChooseAButton.pack()
    OPUSiteButton.pack()

    menuWindow.mainloop()

包含似乎冻结了此导入的代码：

import pyautogui as ag
"""
This import here freezes it.  If I comment out just the import, the 
askdirectory works fine.
"""
from pywinauto import application

def OPUSiteInstall(installFolderPath, setObj):
    path = installFolderPath + '\\OPUSite\\AMI.OPUSite.Setup.msi'
    app = application.Application().Start(r'msiexec.exe /i ' + path)
    Wizard = app['OPUSite Setup']
    Wizard.NextButton.Wait('enabled', 50000)
    Wizard.NextButton.Click()
    Wizard['I &accept the terms in the License 
    Agreement'].Wait('enabled').CheckByClick()
    Wizard.NextButton.Click()
    Wizard.NextButton.Click()
    ag.typewrite(setObj.databaseName)
    ag.press('tab')
    ag.press('space')
    ag.press('tab')
    ag.press('tab')
    ag.typewrite(setObj.password)
    ag.press('tab')
    ag.typewrite(setObj.password)
    ag.press('tab')
    ag.typewrite(setObj.password)
    Wizard.NextButton.Click()
    Wizard.Install.Click()

    Wizard.Finish.Wait('visible', 50000)
    Wizard.Finish.Click()

def rs485Install(installFolderPath, setObj):
    path = installFolderPath + '\\OPUSite\\AMI.RS485AdapterSvc.Setup.msi'
    app = application.Application().Start(r'msiexec.exe /i ' + path)
    Wizard = app['RS485Adapter Setup']
    Wizard.NextButton.Wait('enabled', 50000)
    Wizard.NextButton.Click()
    Wizard['I &accept the terms in the License 
    Agreement'].Wait('enabled').CheckByClick()
    Wizard.NextButton.Click()
    Wizard.NextButton.Click()
    Wizard.Install.Click()

    Wizard.Finish.Wait('visible', 50000)
    Wizard.Finish.Click()

这是我尝试过的穿线衣服。没用：

from InstallMenu import MainMenu
from tkinter import *
from tkinter import filedialog
import threading

def chooseInstallFolder(installFolderPath):
    def callback(installFolderPath):
        filename = filedialog.askdirectory()
        installFolderPath.config(text=filename)
    t = threading.Thread(target=callback, args=(installFolderPath,))
    t.start()

def submitFolder(installFolderApp, installFolderPath, setObj):
    installFolderApp.destroy()
    MainMenu(installFolderPath, setObj)

def chooseInstall(setObj):
    installFolderApp = Tk()
    installFolderApp.title("Find Install Folder")
    installFolderApp.geometry("300x200")

    #Gui items
    pickAFolder = Label(installFolderApp, text = "Select your Install 
    Folder")
    pickInstallerButton = Button(installFolderApp, text="Browse", command = 
    lambda : chooseInstallFolder(installFolderPath))
    installFolderPath = Label(installFolderApp, text = " ")
    submit = Button(installFolderApp, text="Submit", command = lambda : 
    submitFolder(installFolderApp, installFolderPath, setObj))

    #Packing
    pickAFolder.pack()
    installFolderPath.pack()
    pickInstallerButton.pack()
    submit.pack()

    installFolderApp.mainloop()

Answer 1

我能够解决这个问题。我想指出的是，我仍然不确定为什么这样做。我所做的就是将pywinauto导入移至我的函数中，现在askdirectory运行正常。

import pyautogui as ag

def OPUSiteInstall(installFolderPath, setObj):
    from pywinauto import application
    path = installFolderPath + '\\OPUSite\\AMI.OPUSite.Setup.msi'
    app = application.Application().Start(r'msiexec.exe /i ' + path)
    Wizard = app['OPUSite Setup']
    Wizard.NextButton.Wait('enabled', 50000)
    Wizard.NextButton.Click()
    Wizard['I &accept the terms in the License 
    Agreement'].Wait('enabled').CheckByClick()
    Wizard.NextButton.Click()
    Wizard.NextButton.Click()
    ag.typewrite(setObj.databaseName)
    ag.press('tab')
    ag.press('space')
    ag.press('tab')
    ag.press('tab')
    ag.typewrite(setObj.password)
    ag.press('tab')
    ag.typewrite(setObj.password)
    ag.press('tab')
    ag.typewrite(setObj.password)
    Wizard.NextButton.Click()
    Wizard.Install.Click()

    Wizard.Finish.Wait('visible', 50000)
    Wizard.Finish.Click()

def rs485Install(installFolderPath, setObj):
    from pywinauto import application
    path = installFolderPath + '\\OPUSite\\AMI.RS485AdapterSvc.Setup.msi'
    app = application.Application().Start(r'msiexec.exe /i ' + path)
    Wizard = app['RS485Adapter Setup']
    Wizard.NextButton.Wait('enabled', 50000)
    Wizard.NextButton.Click()
    Wizard['I &accept the terms in the License 
    Agreement'].Wait('enabled').CheckByClick()
    Wizard.NextButton.Click()
    Wizard.NextButton.Click()
    Wizard.Install.Click()

    Wizard.Finish.Wait('visible', 50000)
    Wizard.Finish.Click()
