FAILURE: Build failed with an exception.

* Where:
Script 'node_modules\react-native\react.gradle' line: 191

* What went wrong:
Execution failed for task ':app:bundleReleaseJsAndAssets'.
> Process 'command 'cmd'' finished with non-zero exit value 1

(引用的文件存在，至少在构建失败后).

(The referenced file exists, at least after the build failed).

• 在 Windows 10 上构建
• React Native 版本:0.62.2

• 按照 https://github.com/facebook/react-native/issues/25927#issuecomment-539415154

推荐答案

在 build.gradle 中修改以下额外的包定义:

Modifying the following extra packages definition in build.gradle:

extraPackagerArgs: ["--sourcemap-output", "$buildDir/intermediates/assets/release/index.android.bundle.map"]

到

extraPackagerArgs: ["--sourcemap-output", "$buildDir/intermediates/sourcemaps/react/release/index.android.bundle.packager.map"]

修复了错误(警告仍然存在).
一个 APK 已创建并正在运行..

Fixed the error (the warnings are still there).
An APK is created and is running..
