我有个项目目前在某个网站上有。我需要做些改变。当我从gitlab下载一个项目并运行时，它会抛出一个错误：* This must be called within a setup function.*
路径：.nuxt/composition-api/index.js

const useContext = () => {
  const vm = CompositionApi.getCurrentInstance();
  if (!vm)
    throw new Error("This must be called within a setup function.");
  return {
    ...(vm[globalNuxt] || vm.$options).context,
    route: CompositionApi.computed(() => vm.$route),
    query: CompositionApi.computed(() => vm.$route.query),

字符串
怎么了？
我需要运行该项目以进行一些更改，但无法将其部署到本地服务器上。
更新：useContex是默认的。vue

...
setup (_, { isServer, refs }: any) {
    // console.info(context)
    // const refs = context.refs
    const { store } = useContext()
    const { scrolllock } = scrollLock(store)
    const locationName = computed(() => store.getters.locationName)
    const location = computed({
      set (val: boolean) {
        store.dispatch('setLocationModal', val)
      },
      get () {
        return store.getters.locationModal
      }
    })
...

我尝试访问站点时的cmd输出
