It says that You should have installed @angular/compiler version between 2.3.1 and 4.0.0. same about angular/core module and others. Check out your package.json file, it has the list of all module installed with its version. If you haven't installed all modules then run npm install in terminal.You can use latest version by using npm install -g @angular/cli@latest. (You can use any version by writing @(version-number) like @2.5.5 ) in the end. Maybe this post is helpful
