Question

我正在尝试构建我的项目，但是它已变成噩梦...

现在，我在运行@echo off python -m robot %*

时遇到此问题

./gradlew assembleRelease

更具体地说：

org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':app:bundleReleaseJsAndAssets'.

老实说，我绝对不知道现在出了什么问题，该如何调试呢？

这是我的 package.json ：

Answer 1

来自https://www.npmjs.com/package/babel-preset-react-native

babel-preset-react-native已替换为 metro-react-native-babel预设，现在使用Babel 7.0.0。如果你是使用React Native v0.57或更高版本，您应该更新babel配置指向Metro-react-native-Babel预设预设。

Answer 2

我认为这可能与JSON.stringify(responseText)的特定问题有关，您可以尝试此解决方案https://github.com/babel/babel/issues/8263#issuecomment-402546923

添加到您的babel-core

package.json

然后是"babel-plugin-transform-object-rest-spread": "^7.0.0-beta.3"
