使用新的构建系统迁移到 Angular 18 后，我收到一个错误：无法读取 null 的属性（读取“bindingStartIndex”）

Question

我已将用作应用程序库的项目从 Angular 17 更新为 Angular 18，并且像往常一样更新了所有包。我也接受了迁移到新的构建系统。

npm i [email protected]
ng update @angular/core@18 ng update @angular/cli@18 
ng update @angular-eslint/schematics@18 ng update @angular/material@18

当我运行该库时，我在浏览器控制台中收到此错误：

main.ts:10 ERROR TypeError: Cannot read properties of null (reading 'bindingStartIndex')
    at ɵɵelementStart (core.mjs:23501:53)
    at AppComponent2_Template (template.html:1:1)
    at executeTemplate (core.mjs:11788:5)
    at renderView (core.mjs:12950:7)
    at renderComponent (core.mjs:12896:3)
    at renderChildComponents (core.mjs:12996:5)
    at renderView (core.mjs:12978:7)
    at ComponentFactory.create (core.mjs:16260:9)
    at _ApplicationRef.bootstrap (core.mjs:31811:38)
    at core.mjs:33216:56

在我的

package.json

中，我在本地添加了一个包，它是应该渲染的组件，我不知道这是否可能是问题所在，并且某些东西改变了本地导入包的方式。

"@mylib/dashboards": "file:./MyLib.Dashboards/dist/dashboards/mylib-dashboards-18.0.0.tgz"

自从在

tsconfig.json

中我已经添加了角度库的路径，这是我看到人们针对这个问题给出的解决方案

“paths": {
  “@angular/*": [
    “node_modules/@angular/*”
  ],

我也尝试在

angular.json

中添加

preserveSymlinks

部分，但没有任何改变。

 "architect": {
        "build": {
          "builder": "@angular-devkit/build-angular:application",
          "options": {
             "preserveSymlinks": true,

但是，如果我从“

“@angular/*

”中删除此路径，我不会收到错误，但我测试库的模拟数据不会加载。我使用

InMemoryDataService

创建这个模拟数据，它实现了

InMemoryDbService

创建数据库。

您可以尝试从

paths

数组中删除角线，这可能会解决问题。

之前：

“paths": {
  “@angular/*": [
    “node_modules/@angular/*”
  ],

之后：

“paths": {},
