【问题讨论】:
升级后,你是否删除了node_modules文件夹并使用'npm i'恢复了包? @Martino Bordin。是的,我做到了。但我仍然有那个错误 你可以删除你的node_modules,运行npm cache clean --force
,从项目中删除你的package-lock.json,然后再次执行npm install
@AbolfazlR,你的 package.json 是什么样的?
@nircraft 在这里有正确的直觉。回想一下,@angular/*
依赖项应该被列为 peerDependencies
【参考方案1】:
使用 TypeScript 时,您很可能迟早要处理“重复标识符”错误。 但是这个错误究竟意味着什么?再次阅读错误文本。重复的标识符。您在代码中定义了两次相同的标识符(类、方法、属性)。
【讨论】:
【参考方案2】:如果您删除包 angular2-navigate-with-data,一切正常。
删除此包后将数据发送到另一个页面更改代码:
表格
this.router.navigateByData( url: , data: data );
到
this.router.navigateByUrl(url, state: data );
当你想获取数据时:
表格
let data = this.router.getNavigatedData();
到
this.activatedRoute.paramMap.pipe(map(() => window.history.state)).subscribe(data => let data = data );
