vue-cli3.x創建項目vue create hello-world

在git中輸入指令vue create hello-world,沒反應,因為vue-cli的版本問題,必須3.x版本才能使用這個指令於是按照官網的提示升級vue

vue-cli從2.x版本升級到3.x版本卸載包報錯.

根據官網的指令輸入: yarn global remove vue-cli

報錯:

error This module isn't specified in a package.json file.
info Visit https://yarnpkg.com/en/docs/cli/global for documentation about this command.

 

改用npm uninstall vue-cli -g卸載就成功了

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

 

重新安裝后

$ vue --version
3.9.2

 

再次輸入指令: 

vue create my-tetris
