vue-cli3.x创建项目vue create hello-world

在git中输入指令vue create hello-world,没反应,因为vue-cli的版本问题,必须3.x版本才能使用这个指令于是按照官网的提示升级vue

vue-cli从2.x版本升级到3.x版本卸载包报错.

根据官网的指令输入: yarn global remove vue-cli

报错:

error This module isn't specified in a package.json file.

改用npm uninstall vue-cli -g卸载就成功了

vue --version
bash: /c/Users/lsm/AppData/Roaming/npm/vue: No such file or directory

 

重新安装后

$ vue --version
3.9.2

 

再次输入指令: 

vue create my-tetris
