升级到RN 0.30 后,即使构建最简单的app,我也开始看到以下错误:
react-native init AwesomeProject
react-native run-ios
BlurView
,VibrancyView
和RNSearchBar
,但它们仍包含在警告消息中。 控制台和错误:

If you haven't changed this prop yourself, this usually means that your versions of the native code and JavaScript code are out of sync. Updating both should make this error go away.

最佳答案
发生此错误的原因是,在我更新到0.28
之后,React打包程序的另一个实例(仍在0.30
上)正在后台运行。
重新启动React包装程序即可解决该问题。
