Follow the below steps to start with angular CLI.

First update node version:

1. So, first check your node version by typing command node -v.

2. If node version is lower than 6.x.x then update it because angular CLI requires node version to be higher than 6.x.x. To update node version run the below command.

   nvm install <new version> --reinstall-packages-from=<old version>

   Ex: nvm install 7.10.0 --reinstall-packages-from=5.1.0

   Then run command: nvm use 7.10.0

3. After this run command npm install -g @angular/cli to install Angular CLI.

4. Then ng new my-new-project to create new project.
5. Then cd my-new-project to go inside created project directory.
6. And then finally ng serve to run your app.

Extra: To update your angular 2 project into angular 4 project run below command:

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

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

回答2:

In your command line tool use: npm install -g @angular/cli@latest

Make sure you have installed NodeJS first.
