Question

一周前，我开始与react-native一起工作。因此，我已经按照此处所述设置了react-native： https://facebook.github.io/react-native/docs/getting-started.html（使用本机代码的TAB建筑项目）然后，我用“ react-native init ...”命令初始化了新的react-native项目。同样，我已经设置了Android Studio，创建了虚拟android设备，并启动了android仿真器之后，我从项目目录输入了命令react-native run-android。结果，我得到了：

FAILURE: Build failed with an exception.

在这种情况下，我不了解什么是“重置为无效标记”以及如何解决该问题。

使用：赢10 react-native-cli：2.0.1 反应本机：0.58.1 android gradle plugin 3.3.0（也尝试过3.2.1 无济于事） gradle 4.10.2（尝试4.7，无济于事）

Answer 1

问题已解决。卸载所有工具，例如node，python，expo，react-native-cli，已删除的gradle存储库和所有缓存的文件（npm-modules等），然后再从头开始安装。现在就可以了。因此，原因可能是在先前的安装过程中发生了一些未注意到的错误，或者是我的操作系统中的历史混乱
