将 React Native 从 0.69.5 更新到 0.70.3。

应用程序在两个平台上构建，但当它在 Metro 上运行时会出现此错误。

遵循错误文件位置只会将我带到“抛出”语句，当然，index.js 或 app.tsx 上没有重复的依赖项，因为我假设错误只是向上抛出到该文件。我认为...

不管怎样，这已经困扰了我和我的团队两天，希望其他人可能也遇到过这个问题并知道如何调试它。关键undefined是有0%的帮助。

我还没有在 …

这里是非常新的 Python 学习者。

试图构建我的第一个项目，但是 numpy.js 有很多问题。当我尝试运行该程序时，它返回此错误：

    RuntimeError: Polyfit sanity test emitted a warning, most likely due to using a buggy Accelerate backend. If you compiled yourself, see site.cfg.example for information. Otherwise report this to the vendor that provided NumPy.
RankWarning: Polyfit may be poorly conditioned

我想我已经在 VS Code 上正确安装了所有东西，尽管弄清楚这一点也很头疼。

在谷歌上搜索有关加速的错误不断出现，但我不知道如何删除或卸载它......甚至它是什么。

任何提示都会很有帮助！

如果需要更多信息，请告诉我。这是我在这里的第一个问题。

谢谢！:)
