Nuxt、VueJS 这必须在设置函数中调用

Question

我有一个项目。目前可以在某个网站上找到。我需要实施一些改变。当我从 gitlab 下载项目并运行时，它会抛出一个错误：这必须在设置函数中调用。

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),

怎么了？

我需要运行该项目来进行一些更改，但无法将其部署到我的本地服务器上。

更新：useContex 在 default.vue 中

...
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
      }
    })
...

当我尝试访问该网站时的 cmd 输出

[Vue warn]: [vue-composition-api] already installed. Vue.use(VueCompositionAPI) should be called only once.

根据我的经验，npm 无法安装@nuxtjs/composition-api旧版本或类似的东西，所以我确实卸载了旧版本并安装了新版本，它可以工作

这是我所做的

rm -rf node_modules && rm -rf package-lock.json && npm uninstall @nuxtjs/composition-api && npm i @nuxtjs/composition-api && npm i
