pyinstaller 打包错误

我用kivy(一个gui开发模块)制作了一个简单的gui程序，idle运行正常，代码如下：

import os
import kivy
from kivy.app import App
from kivy.uix.label import Label
from kivy.uix.gridlayout import GridLayout
from kivy.uix.textinput import TextInput
from kivy.uix.button import Button
from kivy.uix.screenmanager import ScreenManager,Screen
class ConnectPage(GridLayout):
    def __init__(self,**kwargs):
        super().__init__(**kwargs)
        self.cols = 2
        if os.path.isfile("C:/Users/Administrator/Desktop/informations.txt"):
            with open("C:/Users/Administrator/Desktop/informations.txt","r") as f:
                d = f.read().split(",")
                prev_ip = d[0]
                prev_port = d[1]
                prev_username = d[2]
        else:
            prev_ip = ""
            prev_port = ""
            prev_username = ""

        self.add_widget(Label(text="IP:"))
        self.ip = TextInput(text=prev_ip,multiline=False)
        self.add_widget(self.ip)
        self.add_widget(Label(text="Port:"))
        self.port = TextInput(text=prev_port,multiline=False)
        self.add_widget(self.port)
        self.add_widget(Label(text="Username:"))
        self.username = TextInput(text=prev_username,multiline=False)
        self.add_widget(self.username)
        self.join = Button(text="Join")
        self.join.bind(on_press=self.join_button)
        self.add_widget(Label())
        self.add_widget(self.join)
    def join_button(self,type):
        port = self.port.text
        ip = self.ip.text
        username = self.username.text
        with open("C:/Users/Administrator/Desktop/informations.txt","w") as f:
            f.write(f"{ip},{port},{username}")
        info = f"Attempting to join {ip}:{port} as {username}"
        chat_app.info_page.update_info(info)
        chat_app.screen_manager.current = "Info"
class InfoPage(GridLayout):
    def __init__(self,**kwargs):
        super().__init__(**kwargs)
        self.cols = 1
        self.message = Label(halign="center",valign="middle",font_size=30)
        self.message.bind(width=self.update_text_width)
        self.add_widget(self.message)
    def update_info(self,message):
        self.message.text = message
    def update_text_width(self,*_):
        self.message.text_size = (self.message.width*0.9,None)
class EpicApp(App):
    def build(self):
        self.screen_manager = ScreenManager()
        self.connect_page = ConnectPage()
        screen = Screen(name="Connect")
        screen.add_widget(self.connect_page)
        self.screen_manager.add_widget(screen)
        self.info_page = InfoPage()

        screen = Screen(name="Info")
        screen.add_widget(self.info_page)
        self.screen_manager.add_widget(screen)
        return self.screen_manager
if __name__ == "__main__":
    chat_app = EpicApp()
    chat_app.run()

当我在命令行输入pyinstaller -F main.py（上面代码文件），打包没有异常。
之后我尝试打开exe，报错了：

（这是我在闪退的瞬间拍到的）
经过一段时间，我按照kivy打包指南，先弄spec文件，修改，然后编译。结果是一样的错误。

我又试着后面加上–hidden-import pyg_resources.py2_warn。
但还是报了同样的错误。

有哪位大佬知道如何解决？
