Question

我正面临这个错误并试图从互联网上研究但没有运气。它只是突然发生没有理由所以我不知道如何重现错误。我遵循了这个解决方案（https://github.com/facebook/react/issues/8454）。试图卸载，再次安装反应js但仍然相同。有人可以帮忙看看这个吗？非常感谢。这是我的package.json

Answer 1

我有同样的错误，我相信它与不同版本的React和React Native有关。

例如，RN 0.51需要React 16.0的对等依赖性。在我的情况下，我有16 alpha并导致错误。我建议你尝试安装相应版本的React。

希望它有所帮助。

Answer 2

我遇到同样的错误...... 我只是将react-native版本更改为0.49.0。工作得很好。

Undefined不是函数（评估'ReactComponentTreeHook.purgeUnmountedComponents（）'
