我将我的角度项目和所有依赖项更新到最新版本.我没有遇到太多麻烦,我解决了大多数依赖问题,但我仍然坚持使用RxJs.这是我的package.json:

  "dependencies": {
    "@angular-devkit/build-angular": "^0.6.0",
    "@angular/animations": "^6.0.0",
    "@angular/common": "^6.0.0",
    "@angular/compiler": "^6.0.0",
    "@angular/core": "^6.0.0",
    "@angular/forms": "^6.0.0",
    "@angular/http": "^6.0.0",
    "@angular/platform-browser": "^6.0.0",
    "@angular/platform-browser-dynamic": "^6.0.0",
    "@angular/router": "^6.0.0",
    "angular-bootstrap-md": "^6.0.1",
    "core-js": "^2.5.5",
    "font-awesome": "^4.7.0",
    "rxjs": "^6.1.0",
    "zone.js": "^0.8.26"
  },
  "devDependencies": {
    "@angular/cli": "~6.0.0",
    "@angular/compiler-cli": "^6.0.0",
    "@angular/language-service": "6.0.0",
    "@types/jasmine": "~2.8.3",
    "@types/jasminewd2": "~2.0.3",
    "@types/node": "~6.0.60",
    "codelyzer": "^4.0.1",
    "electron": "^1.8.3",
    "jasmine-core": "~2.8.0",
    "jasmine-spec-reporter": "~4.2.1",
    "karma": "~2.0.2",
    "karma-chrome-launcher": "~2.2.0",
    "karma-coverage-istanbul-reporter": "^1.4.2",
    "karma-jasmine": "~1.1.2",
    "karma-jasmine-html-reporter": "^1.0.0",
    "protractor": "~5.3.1",
    "ts-node": "~6.0.2",
    "tslint": "~5.10.0",
    "typescript": "~2.7.2"

我只是从RxJs导入模块:

import { fromPromise } from …

所以我正在为我的网络应用程序设置一个清单文件，并且需要一个有效的图标才能工作。遵循MDN结构，我为我的应用程序提供了多个图标。到目前为止，这是我的清单：

{
  "name": "Tradesolution EPD",
  "short_name": "EPD portal",
  "theme_color": "#007AB5",
  "display": "standalone",
  "start_url": "http://localhost:1384/#/",
  "icons": [
    {
      "src": "content/images/favicon.ico",
      "sizes": "144x144"
    },
    {
      "src": "content/images/favicon.ico",
      "sizes": "16x16"
    },
    {
      "src": "content/images/ts-logo.svg",
      "sizes": "72x72"
    },
    {
      "src": "content/images/ts-logo.svg",
      "sizes": "512x512"
    }
  ],
  "background_color": "#007AB5", 
  "orientation": "portrait" 
}

我在尝试添加清单的控制台中收到以下错误：

Site cannot be installed: 
icon downloaded from the manifest was empty or corrupted

这是我来自 devtools 的清单概述。

根据 W3C 标准清单验证器，我的 manifest.json 文件也是有效的

更新：所以我用带有以下参数的新图像更新了我的清单：

{
  "src": "content/images/pakningssammensetninger/new-B_diagram.png",
  "sizes": "192x192",
  "type": "image/png" …
