为什么这段代码编译后会抛出错误答案

【问题描述】：

我做了一个脚本，它运行良好，但是当我用 pyinstaller 编译它时

pyinstaller --onefile --icon='icon.ico' dmi.py

它会抛出错误，但如果我不编译它会起作用

我知道 Github 模块正在抛出错误。这是抛出错误的代码：

import PySimpleGUIQt as Sg
from github import Github
from urllib import parse

g = Github("ghp_**********************************")
img_data = (g.get_user().get_repo('python-files')).get_contents(
    parse.quote('create.ico'), ref="main").content.replace('\n', '').encode()

layout = [
    [Sg.Text('                                                     ')]
]
window = Sg.Window("Add Tags", layout, icon=img_data, resizable=False, finalize=True)
while True:
    event, values = window.read()
    if event == Sg.WINDOW_CLOSED:
        window.close()
        break

以下代码即使在编译后也能正常工作：

import base64
import PySimpleGUIQt as Sg
import requests
header = {"Authorization": "token ghp_*******************************",
          "Accept": "application/vnd.github.v4.raw"}
encoded = base64.b64encode((requests.get('https://raw.githubusercontent.com/WoLvES-2x0/python-files/main/create.ico', headers=header)).content)
layout = [
    [Sg.Text('                                                     ')]
]
window = Sg.Window("Add Tags", layout, icon=encoded, resizable=False, finalize=True)
while True:
    event, values = window.read()
    if event == Sg.WINDOW_CLOSED:
        window.close()
        break

虽然我可以通过其他方式做到这一点，但如果没有这个，我将面临的主要问题是

Get file name of all files in a repo

g_f_name = [str(i).replace('ContentFile(path="', '').replace('")', '') for i in (g.get_user().get_repo('node-files')).get_contents('') if i]

并且 commit changes to repo

repo.update_file(repo.get_contents('tags.txt').path, "committing files", tags_string, repo.get_contents('tags.txt').sha, branch="main")

错误是

【问题讨论】：

您能否使用edit 将错误添加到您的问题中？
我不能因为我没有权限添加图像，因为错误显示在控制台中，并且在我暂停控制台之前错误关闭，它会停留 100 或 200 毫秒，我必须使用“即时重播”查看错误，但它不是文本格式
所以，您所说的这个错误可能对我们能够回答这个问题非常重要。尽可能多地告诉我们。请参阅How to Ask 以及如何创建minimal reproducible example。
如果您从控制台运行程序，控制台将在之后保留。
当我遇到这种情况时，我喜欢用手机拍摄屏幕视频，然后慢慢滑过它来阅读它（不是花哨但有效）。

【解决方案1】：

导入

import _cffi_backend

解决了这个问题，我认为是 Pyinstaller 在编译时不知何故错过了这个模块，而 PyGithub 需要这个模块，虽然在编辑器中这个是灰色的，但它可以工作
