作为Dev运行项目工作正常,但作为Release运行会产生以下错误.

warning: the transform cache was reset.

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.

/Users/macintoshhd/Documents/TGS/mow/node_modules/rx/dist/rx.all.js: Cannot convert object to primitive value

你有什么建议吗,请帮忙.
谢谢！

最佳答案 我花了几天时间来计算node_modules / rx / dist / rx.all.js的原因：无法通过注释所有代码并逐个取消注释将对象转换为原始值错误.

当我在自动完成弹出窗口后巧合按Enter键时,VS Code会自动导入未知库.它是

import { AsyncSubject } from 'rx';

删除import语句后,我在Release模式下成功构建项目.

当以Dev模式运行时,这种错误不会抛出异常:(,除了为Release构建时.
