无法将现有的Angular Cli项目升级到Angular 4 Rc1 [英] Cannot Upgrade a Existing Angular Cli project to Angular 4 Rc1

问题描述

我正在尝试使用以下命令升级到Angular 4 Rc1

I am trying to use the following command to upgrade to Angular 4 Rc1

npm install @angular/{common,compiler,compiler-cli,core,forms,http,platform-browser,platform-browser-dynamic,platform-server,router,animations}@next --save

这是可以转换为角度4的命令

This is the command that is suppose to work to convert to angular 4

https://github.com/angular/angular/blob/master/CHANGELOG.md

但是这个命令给我一个错误

But this Command is giving me a error

推荐答案

如果此命令不起作用

npm install @angular/{common,compiler,compiler-cli,core,forms,http,platform-browser,platform-browser-dynamic,platform-server,router,animations}@next --save

然后像这样单独尝试-

npm install @angular/common@next --save
npm install @angular/compiler@next --save
npm install @angular/compiler-cli@next --save
npm install @angular/core@next --save
npm install @angular/forms@next --save
npm install @angular/http@next --save
npm install @angular/platform-browser@next --save
npm install @angular/platform-browser-dynamic@next --save
npm install @angular/platform-server@next --save
npm install @angular/router@next --save
npm install @angular/animations@next --save

分别运行命令对我有帮助，现在 package.json 中的依赖项看起来像这样-

Running commands individually helps for me and now dependencies in package.json looks like this-

"@angular/animations": "^4.0.0-rc.1",
"@angular/common": "^4.0.0-rc.1",
"@angular/compiler": "^4.0.0-rc.1",
"@angular/compiler-cli": "^4.0.0-rc.1",
"@angular/core": "^4.0.0-rc.1",
"@angular/forms": "^4.0.0-rc.1",
"@angular/http": "^4.0.0-rc.1",
"@angular/platform-browser": "^4.0.0-rc.1",
"@angular/platform-browser-dynamic": "^4.0.0-rc.1",
"@angular/platform-server": "^4.0.0-rc.1",
"@angular/router": "^4.0.0-rc.1", 

请记住，您需要打字稿":"^ 2.1.6"，
