Angular 9 mat-progress-buttons error: ERROR in Failed to compile entry-point mat-progress-buttons (es2015 as esm2015) due to compilation errors

Question

从 Angular 8 更新到 Angular 9 后，下面给出的 mat-progress-button 出现错误。它与 Angular 8 一起工作正常。MatProgressButton 是否与 Angular 9 不兼容？

node_modules/mat-progress-buttons/esm2015/mat-progress-buttons.js:181:26 - error NG1010: Value at position 1 in the NgModule.imports of MatProgressButtonsModule is not a reference: [object Object]

导入看起来像： import { MatProgressButtonsModule } from 'mat-progress-buttons';

我的 package.json 看起来像这样：

  "dependencies": {
    "@angular/animations": "^9.0.2",
    "@angular/cdk": "^9.1.0",
    "@angular/common": "~9.0.2",
    "@angular/compiler": "~9.0.2",
    "@angular/core": "~9.0.2",
    "@angular/forms": "~9.0.2",
    "@angular/material": "^9.1.0",
    ...
    "@angular/router": "~9.0.2",
    "core-js": "^2.5.4",
    "mat-file-upload": "^1.3.2",
    "mat-progress-buttons": "^8.0.7",
    "rxjs": "~6.5.4",
    "tslib": "^1.10.0",
    "zone.js": "~0.10.2"
  },
  "devDependencies": {
    "@angular-devkit/build-angular": "~0.900.3",
    "@angular/cli": "~9.0.3",
    "@angular/compiler-cli": "~9.0.2",
    "@angular/language-service": "~9.0.2",
   ...
    "typescript": "^3.7.5"
  }
}

Answer 1

我遇到了同样的问题。似乎已安装模块的版本存在某种错误。我通过删除解决了它 node_module 文件夹并用 npm install.

重新启动它

Answer 2

已删除 node_modules 文件夹、dist 文件夹和 package-lock。json 文件

npm cache clean --force
npm cache verify
npm i

然后它对我有用！
