我继承了这个CLJS React Native代码库,并试图将Android SDK升级到带有React 16.4和RN 0.56的v26。调试版本的效果很好,但在使用以下调用堆栈启动时,发布版本将失败:

关于如何获取未缩小版本的调用堆栈的任何想法?缩小是由cljs到js编译器完成的吗?还是RN捆绑器/打包器?
我目前正在对cljs to js编译器使用高级优化。如果将其切换为空白优化,则会出现构建错误
transform[stderr]: FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory
我可以通过单独进行捆绑来解决它
node --expose-gc --max_old_space_size=4096 ./node_modules/react-native/local-cli/cli.js bundle --verbose --platform android --dev true --reset-cache --entry-file index.android.js --bundle-output /usr/src/app/android/app/build/intermediates/assets/release/index.android.bundle --assets-dest /usr/src/app/android/app/build/intermediates/res/merged/release
但是我遇到了另一个失败
Unable to load script from assets 'index.android.bundle'.
有什么想法我还能尝试吗?
更新1:“无法从资产'index.android.bundle'加载脚本。”错误消息是由于将index.android.bundle文件放置在错误的文件夹中引起的。以下命令有效:
node --expose-gc --max_old_space_size=4096 ./node_modules/react-native/local-cli/cli.js bundle --verbose --platform android --dev true --reset-cache --entry-file index.android.js --bundle-output /usr/src/app/android/app/src/main/assets/index.android.bundle --assets-dest /usr/src/app/android/app/src/main/res/
未缩小的调用堆栈如下:

答案 0 :(得分:0)
我用react-native-git-upgrade重新启动RN升级过程后,APK工作正常。升级后还有另一个问题,运行时出现一些未解决的符号,但事实证明这是externs文件的问题,因为我已从不赞成使用的BackAndroid切换到BackHandler。
