我把安裝喲發電機像角，角fullstack，CG-角度使用這些命令：

npm install -g generator-angular 
npm install -g generator-angular-fullstack 
npm install -g generator-cg-angular 

但是，當我嘗試喲命令我不使用它們找不到它們

You don't seem to have a generator with the name angular:controller installed. 
You can see available generators with npm search yeoman-generator and then install them with npm install [name]. 
To see the 1 registered generators run yo with the `--help` option.

我相信如果你使用「npm clean cache」並嘗試使用相同的命令就可以解決。
