Angular2升级到Angular4

angular4终于在两天前发布了正式版本,那么怎么升级呢?其实angular2和angular4之间属于平滑过渡,并不像1和2之间颠覆性的重写代码.

npm uninstall -g @angular/cli
 npm cache clean
 npm install -g @angular/cli@latest
 
 rm -rf node_modules dist # use rmdir /S/Q node_modules dist in Windows Command Prompt; use rm -r -fo node_modules,dist in Windows PowerShell
 npm install --save-dev @angular/cli@latest

1. 升级包

// linux/mac
 npm install @angular/{common,compiler,compiler-cli,core,forms,http,platform-browser,platform-browser-dynamic,platform-server,router,animations}@latest typescript@latest --save
 // Windows
 npm install @angular/common@latest @angular/compiler@latest @angular/compiler-cli@latest @angular/core@latest @angular/forms@latest @angular/http@latest @angular/platform-browser@latest @angular/platform-browser-dynamic@latest @angular/platform-server@latest @angular/router@latest @angular/animations@latest typescript@latest --save

1. 更换一些其他包

 npm install zone.js@0.8.4 --save

1. 执行安装命令
