vue 报 @vue/composition-api/dist/vue-composition-api.mjs

vue 安装 vue-echarts 之后报错：

This dependency was not found:

* @vue/composition-api/dist/vue-composition-api.mjs in ./node_modules/vue-demi/lib/index.mjs

To install it, you can run: npm install --save @vue/composition-api/dist/vue-composition-api.mjs

 

只需要安装：@vue/composition-api

npm install --save @vue/composition-api
