需要安裝角2，而不是角4安裝

我正在嘗試使用angular-cli獲取角2項目並運行。我認爲在看到我的Package.json後，角4安裝而不是角2。有人能告訴我正確的做法嗎？需要安裝角2，而不是角4安裝

我用下面的命令來安裝角

npm install -g @angular/cli 
ng new projectname

的package.json

可能的[使用角度cli安裝特定版本的角度]的副本（https://stackoverflow.com/questions/43344600/installing-a-specific-version-of-angular-with-angular-cli） –

您可以檢查https://stackoverflow.com/documentation/angular2/789/getting-started-with-angular-2/26878/getting-started-with-angular-2-with-node-js-expressjs-的package.json，後端http-example-incl＃t = 201705301731505556728但我建議你去angular4 – echonax

從1.0版本開始，Angular/CLI默認使用Angular 4（請參閱[changelog]（https://github.com/angular/angular- CLI /斑點/主/ CHANGELOG.md＃100-2017-03-24）） – crashmstr

編輯您的package.json到：

"dependencies": { 
    "@angular/common": "2.0.0", 
    "@angular/compiler": "2.0.0", 
    "@angular/core": "2.0.0", 
    "@angular/forms": "2.0.0", 
    "@angular/http": "2.0.0",

然後取出node_modules文件夾rm -rf node_modules和再次運行npm i
