Vue project build failed to initialize

I built vue scaffolding on the win10 system, vue-cli has been set up, then initialized the project with vue init webpack vueRouterTest , and then reported an error. The error is as follows:

  Unknown command init.
  vue-cli  Failed to download repo vuejs-templates/[object Object]: Response code 404 (Not Found)

the relevant error contents and solutions can not be found on the Internet. Ask God for advice.
