由于 Windows 桌面上的 OpenGL 要求导致的 kivy 致命错误答案

【问题标题】：kivy fatal error due to OpenGL requirement on windows desktop由于 Windows 桌面上的 OpenGL 要求导致的 kivy 致命错误
【发布时间】：2016-04-01 10:21:53
【问题描述】：

我使用 Python 2.7 和 kivy 编写了一个 Windows 桌面应用程序，它在 pyCharm IDE 和 python 命令行中运行良好。使用 PyInstaller 构建分发包后，从 ..\dist\applicdir\ 运行应用程序，我收到 Kivy 致命错误：

GL：未找到最低要求的 OpenGL 版本 (2.0)！

怎么会？它在同一台 PC 上从 2 个不同的角度运行，但不是从同一台 PC 上的 dist 包运行。

你能解释一下为什么在前两种情况下我没有得到致命错误吗？

【问题讨论】：

类似this one的错误？
是的。我已经更新了显卡驱动，问题就解决了。但是在创建 PyInstaller 包后仍然无法让我的应用程序运行。现在“kivy”屏幕变黑了……
尝试 touchtracer，如果它有效，则说明您的代码有问题。还有一些调试（在 pyinstaller 中使用 --debug 启用）日志会很好。
我测试了一个简单的自己开发的 kivy 应用程序，它运行良好。关注的应用程序利用了多处理。并查看一些帖子，这会给 PyInstaller 带来问题。应用程序陷入无限循环，产生进程和黑色窗口并消耗内存，直到机器完全阻塞。
我在上面添加了一些日志信息。见“>>>>>> EDIT 1

【解决方案1】：

更新显卡驱动解决了这个问题。但仍然是一个奇怪的情况，在创建 PyInstaller 包后，应用程序会触发 OpenGL 版本问题，而 PyCharm IDE 和 Python 命令行却没有......
