angular - 如何从 Angular 4 更新/升级到 Angular 5+

Question

我需要将我的项目从 Angular 4 更新到 Angular 5+，

我需要将以下所有依赖项更改为 Angular 5+。

我还将 Angular CLI 更新到 1.5.0。

我尝试创建新项目，但它似乎只创建了 Angular 4 项目。

ng new NG5_Project

"dependencies": {
  "@angular/animations": "^4.2.4",
  "@angular/common": "^4.2.4",
  "@angular/compiler": "^4.2.4",
  "@angular/core": "^4.2.4",
  "@angular/forms": "^4.2.4",
  "@angular/http": "^4.2.4",
  "@angular/platform-browser": "^4.2.4",
  "@angular/platform-browser-dynamic": "^4.2.4",
  "@angular/router": "^4.2.4",
  "core-js": "^2.4.1",
  "rxjs": "^5.4.2",
  "zone.js": "^0.8.14"
}

我做错了什么。

命令行配置:

此特定问题已通过 Node 版本更新得到修复。

我必须更新 Node 版本，

sudo apt-get install nodejs

npm uninstall -g @angular/cli

npm cache clean

npm install -g @angular/cli@latest

ng new ProjectName

node --version ==> 8.9.0

ng --version ==> 1.5.0

"dependencies": {
    "@angular/animations": "^5.0.0",
    "@angular/common": "^5.0.0",
    "@angular/compiler": "^5.0.0",
    "@angular/core": "^5.0.0",
    "@angular/forms": "^5.0.0",
    "@angular/http": "^5.0.0",
    "@angular/platform-browser": "^5.0.0",
    "@angular/platform-browser-dynamic": "^5.0.0",
    "@angular/router": "^5.0.0",
    "rxjs": "^5.5.2",
    "zone.js": "^0.8.14"
}

现在还有官方的 Angular 更新指南:https://update.angular.io

您可以通过适当的步骤将 Angular 版本从最低 v2.0 更新到最新版本(当前为 v15.0)
