Uncaught TypeError: Cannot read properties of undefined (reading 'use')

Question

vue项目运行报错 一脸懵逼 Uncaught TypeError: Cannot read properties of undefined (reading 'use') TypeError:无法读取undefined的属性(读取use')

Answer 1

如果你是vue3的话，检查一下你的main.js的use语句是不是这样写的
createApp(App).use(xxx).use(xxx).use(xxx).mount('#app')

Answer 2

vue2才会使用这个Vue.use(xxx)
