在Angular 5中构建产品时遇到问题

Question

我尝试运行ng build --prod命令，我的应用程序

但是如果我运行ng build命令，我不会遇到任何问题：

这是在部署“ ngx-bootstrap-product-tour”软件包之后发生的。

我的应用程序设置：

 "dependencies": {
    "@angular/animations": "^5.2.0",
    "@angular/common": "^5.2.0",
    "@angular/compiler": "^5.2.0",
    "@angular/core": "^5.2.0",
    "@angular/forms": "^5.2.0",
    "@angular/http": "^5.2.0",
    "@angular/platform-browser": "^5.2.0",
    "@angular/platform-browser-dynamic": "^5.2.0",
    "@angular/router": "^5.2.0",
    "@ng-bootstrap/ng-bootstrap": "^2.0.0",
    "angular2-notifications": "^1.0.2",
    "angular2-text-mask": "^9.0.0",
    "bootstrap": "^4.1.3",
    "classlist.js": "^1.1.20150312",
    "core-js": "^2.4.1",
    "json-typescript-mapper": "^1.1.3",
    "jwt-decode": "^2.2.0",
    "ng2-go-top-button": "^6.0.0",
    "ng4-loading-spinner": "^1.1.3",
    "ngx-bootstrap": "^3.0.1",
    "ngx-bootstrap-product-tour": "^2.0.2",
    "ngx-clipboard": "^11.1.1",
    "rxjs": "^5.5.6",
    "web-animations-js": "^2.3.1",
    "zone.js": "^0.8.19"
  }
}

{
  "extends": "../tsconfig.json",
  "compilerOptions": {
    "outDir": "../out-tsc/app",
    "baseUrl": ".",
    "paths": {
      "@app/*": ["app/*"] 
    },
    "module": "es2015",
    "types": []
  },
  "exclude": [
    "test.ts",
    "**/*.spec.ts"
  ]
}

我该如何解决这个问题？
