Question

我已经安装了PrimeNg并尝试使用侧边栏组件但是当我运行我的项目时出现此错误

ERROR in /home/haddad/projects/node_modules/primeng/components/sidebar/sidebar.d.ts (1,97): Cannot find module '@angular/core'.
ERROR in Error: Metadata version mismatch for module /home/haddad/projects/node_modules/primeng/components/sidebar/sidebar.d.ts, found version 4, expected 3, resolving symbol AppModule in /home/haddad/projects/ar/arrt/src/app/app.module.ts, resolving symbol AppModule in /home/haddad/projects/ar/arrt/src/app/app.module.ts

我应该使用angular 4，所以我将PrimeNg版本修改为4.2.1而不是5v

这是 package.json 文件

"dependencies": {
  "@angular/animations": "^4.3.4",
  "@angular/common": "~4.3.4",
  "@angular/compiler": "~4.3.4",
  "@angular/core": "~4.3.4",

  "protractor": "~5.1.2",
  "ts-node": "~4.1.0",
  "tslint": "~5.9.1",
  "typescript": "~2.1.0"
}

我的 module.ts 文件：

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import {SidebarModule} from 'primeng/sidebar';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { AppComponent } from './app.component';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,SidebarModule,BrowserAnimationsModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

Answer 1

这可能是版本问题和版本不匹配

尝试制作

primeng:^4.2.4

Answer 2

尝试再次执行此操作。

npm install primeng --save

npm install primeicons --save

并确保您的pack-lock.json具有此

"dependencies": {
  //...
  "primeng": "^7.0.0",
  "primeicons": "^1.0.0"
},

Answer 3

我有类似的问题：

ERROR in ../node_modules/primeng/components/checkbox/checkbox.d.ts(1,49): error TS2307: Cannot find module '@angular/core'.
../node_modules/primeng/components/checkbox/checkbox.d.ts(2,51): error TS2307: Cannot find module '@angular/forms'.
../node_modules/primeng/components/listbox/listbox.d.ts(1,103): error TS2307: Cannot find module '@angular/core'.
../node_modules/primeng/components/listbox/listbox.d.ts(3,38): error TS2307: Cannot find module '@angular/forms'.

使用npm重新安装primeng解决了该问题

使用PrimeNg时找不到模块'@ angular / core'
