Today problem occurs with vue-cli themselves, there is a problem of failure when using vue init webpack project this command, the program feeling on Baidu are not reliable
Record yourself this:
First is to check vue, node, webpack is installed, -v (vue uppercase V) can be seen
If you have installed or there is a problem, try the following code (provided that you configure a local git):
git clone https://github.com/vuejs-templates/webpack-simple
vue init ./webpack-simple my-project
This is to webpack packages on github down down, and then based on this package when init on it
