从 Angular 8 更新到 Angular 9 后，下面给出的 mat-progress-button 出现错误。
它在 Angular 8 上运行良好。 MatProgressButton 与 Angular 9 不兼容吗？
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"

}
}
最佳答案
我遇到过同样的问题。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文件夹并使用 npm install 重新启动它.
