作为Dev运行项目工作正常,但作为Release运行会产生以下错误.

我试图用–dev = false手动捆绑项目

react-native bundle --entry-file='index.js' --bundle-output='./ios/main.jsbundle' --dev=false --platform='ios' --assets-dest='./ios'

我得到了这个错误输出

将–dev = false更改为–dev = true,这些输出的buid成功

react-native bundle --entry-file='index.js' --bundle-output='./ios/main.jsbundle' --dev=true --platform='ios' --assets-dest='./ios'

我试过了
– 清洁和重建
– 删除node_modules并重新安装
– 清理Derived文件夹,重启Xcode,
但他们都没有解决这个问题.

这似乎是主要问题.

你有什么建议吗,请帮忙.
谢谢！
