Angular 9 mat progress buttons错误：由于编译错误，未能编译入口点mat progress buttons（es2015为esm2015）中的错误

从角度8更新到角度9后，下面给出的mat进度按钮出现错误。 它与Angular 8配合得很好。按钮是否与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]

导入内容如下所示：

从“mat进度按钮”导入{MatProgressButtonsModule}

My package.json如下所示：

  "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"
  }
}


我也有同样的问题。安装的模块版本似乎存在某种错误。我通过删除
node\u模块
文件夹，并使用
npm安装
删除的node\u模块文件夹、dist文件夹和package-lock.json文件重新初始化它

npm cache clean --force
npm cache verify
npm i

然后我就成功了
 我有同样的问题（这里是我的），它似乎与Angular 9如何处理深度导入有关，但我找不到任何解决方案。
