我将 kivy 与 pickle 一起使用，它工作正常.

Im using kivy with pickle and it works correctly.

from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.config import Config
import pickle
FRAMES_PER_SECOND = 60.0
Config.set('graphics','multisamples',2)

a = []
class Display(BoxLayout):

   def save(self,text):
       with open('db.prz','wb') as file:
           pickle.dump(text,file)
   def loads(self):
       with open('db.prz','rb') as file:
           a = pickle.load(file)
       print(a)

class TestApp(App):
     def build(self):
        a = Display()
        return a

if __name__ == '__main__':
    TestApp().run()

kv 文件:

<Display>:
BoxLayout:
    orientation: 'vertical'
    TextInput:
        id: kvtext
        size_hint_y : 0.2
    BoxLayout:
        orientation : 'horizontal'
        Button:
            text: 'Save'
            on_press: root.save(kvtext.text)
        Button:
            text: 'Load'
            on_press: root.loads()

规范文件更改:

# -*- mode: python ; coding: utf-8 -*-

from kivy_deps import sdl2, glew

a = Analysis(
         datas=[('C:\\Users\\mnt\\Documents\\build_test\\test.kv','.')],
coll = COLLECT(
        *[Tree(p) for p in (sdl2.dep_bins + glew.dep_bins)],

请注意，我没有将我的文件 'db.prze' 添加到 Analysis()

Note that im not adding my file 'db.prze' to data in Analysis()

我也是从github而不是pip安装了pyi.

I also installed pyi from github not from pip.

如果您正在加载类对象，请从文件中导入其类.

If you are loading class object, import its class from file.
