本文介绍了如何在Vue项目中通过npm安装并配置vue-echarts，重点讲解了在VUECLI项目中设置transpileDependencies和在Hello.vue组件中实现雷达图的步骤。还提到了必须安装@vue/composition-api。

Hello, `vue-charts`!

NPM安装。See https://github.com/ecomfe/vue-echarts/blob/5.x/README.zh_CN.md。

npm install echarts vue-echarts

通过VUE CLI创建的项目，必须修改vue.config.js。See https://github.com/ecomfe/vue-echarts/blob/5.x/README.zh_CN.md。

module.exports = {
  transpileDependencies: ["vuetify", "vue-echarts", "resize-detector"],
};

必须安装@vue/composition-api。See https://www.npmjs.com/package/@vue/composition-api。

yarn add @vue/composition-api

样例hello.vue部分。
