把里面的 ForEach 注释掉,就能正常运行,

有demo吗?看看你的demo。可能是你的用法有问题。没有相关demo,无法分析。

和我报错一样,网络请求回来的列表,forEach 就报这个错
在HarmonyOS鸿蒙Next中,嵌套ForEach遍历远程模拟器报错可能由以下几个原因引起:
-
资源限制:远程模拟器在运行复杂嵌套循环时可能因资源(如CPU、内存)不足而导致性能瓶颈或错误。检查嵌套循环的逻辑,确保没有创建过多的临时对象或消耗过多资源。
-
代码逻辑错误:嵌套ForEach中可能存在逻辑错误,如数组越界、变量作用域冲突等。仔细检查循环内部和循环之间的变量使用,确保逻辑正确无误。
-
API使用不当:如果在ForEach中使用了鸿蒙系统特定的API,且使用方式不当,也可能导致报错。查阅相关API文档,确保API的使用符合规范。
-
模拟器兼容性问题:某些HarmonyOS特性或API在远程模拟器上可能不完全支持或存在bug,导致报错。尝试更新模拟器版本或查看模拟器支持的特性列表。
-
异常处理:检查代码中是否有适当的异常处理逻辑,以便在发生错误时能够捕获并处理异常,避免程序崩溃。
