未发现错误的详细信息
google查询说要把gradlew权限修改,然而还是不成功.
思考:命令执行到./gradlew installDebug就没了.那单独执行下看看.
发现错误!!!:-bash: ./android/gradlew: /usr/bin/env: bad interpreter: Operation not permitted
最后解决方法:
Try:
xattr -l ./gradlew
and
xattr -d com.apple.quarantine ./gradlew
unable to load script from assets 'index.android bundle'.
查到旧的解决方法已经不能成功了,没其它提示,只能终极解决了.
删除所有打包文件,重新运行成功!
3.Module HMRClient is not a registerd callable module
打开hot reload后加载报错.
android Q 新版本不支持后台运行.
4.transparent (指定背景颜色应该是透明的。这是默认)
5.android Q字体大小不自动变换.
系统设置调整大小
6.ios下表现正常,android打开hot reload 报错,联接不上服务器.修改代码后reload也不生效.
无赖,重新init项目,copy代码.运行解决.
