今天升级 angular8 出问题了，来帮忙

Question

• 几个月没看的项目，今天发现 angular 更新到8 了，那么就想着拿老项目升级到8试试看
• 结果出问题了。。。

• 下面列出我的 package.json

{
  "name": "source",
  "version": "0.0.0",
  "scripts": {
    "ng": "ng",
    "start": "ng serve",
    "build": "ng build --configuration=production",

    "e2e": "ng e2e"
  },
  "private": true,
  "dependencies": {

    "@angular/common": "^7.2.7",
    "@angular/compiler": "^7.2.7",

  },

    "@angular-devkit/build-angular": "~0.13.0",
    "@angular/cli": "~7.3.3",
    "@angular/compiler-cli": "^7.2.7",
    "@angular/language-service": "^7.2.7",
    "@types/jasmine": "~2.8.6",
    "@types/jasminewd2": "~2.0.3",
    "@types/node": "~8.9.4",
    "codelyzer": "~4.2.1",
    "jasmine-core": "~2.99.1",
    "jasmine-spec-reporter": "~4.2.1",
    "karma": "~1.7.1",
    "karma-chrome-launcher": "~2.2.0",
    "karma-coverage-istanbul-reporter": "~2.0.0",

    "ts-node": "~5.0.1",
    "tslint": "~5.9.1",
    "typescript": "^3.4.5"
  }
}

• 这里的 TS 版本号是3.4.5，应该是兼容的版本了吧？为什么还升级还提示版本不兼容？
• 我接下来要怎么做才能把项目升级到 angular8 ？
