1： If you have already installed vue-cli2 In my words , You have to unload it first , The order is as follows
// First check to see if it has been installed vul-cli vue -V // If there is one , Just use the following command to unload npm uninstall vue-cli -g
2: install vue-cli 4.0.5
// One click initialization project npm init -y // install vue-cli npm install @vue/cli -g // It can also be used cnpm To install
, It's faster cnpminstall @vue/cli -g
