echarts ERROR! Cannot read properties of undefined (reading ‘type‘)

`
const chartPie = ref(null)
chartPie.value = echarts.init(document.querySelector(‘.echarts-pie’), null, { renderer: ‘svg’ })

这种就是错误的

const chartPie = echarts.init(document.querySelector(‘.echarts-pie’), null, { renderer: ‘svg’ })
`

这个不要用 ref 来赋值echarts 实例
