Hi,

After the last update for version 0.8, i cannot run build on my app:

Can't reproduce on my side, can you try a clean install or provide a minimal reproduction? Thanks

For me it's the same error after upgrading to v0.8. I use it in a vue2 web-component project, where vue and @vue/composition-api are located in the devDependencies.

[antfu]

Can I have the content of vue-demi/lib/index.esm.mjs? Still, ideally a repro is preferred.

[lstoeferle]

Unfortunately I can not share the repo, since it belongs to the company I'm working for :(
vue2, vue-demi, @vue/composition-api, @vue/cli (webcomponent build), webpack

// vue-demi/lib/index.esm.mjs
import Vue from 'vue'
import VueCompositionAPI from '@vue/composition-api'

function install(_vue) {
  _vue = _vue || Vue
  if (_vue && !_vue['__composition_api_installed__'])
    Vue.use(VueCompositionAPI)
}

install(Vue)

var isVue2 = true
var isVue3 = false
var Vue2 = Vue
var version = Vue.version

Still having the same error after update 0.8.1
@antfu , i'm gonna add you to the repo. Do you have gitlab account?

i m having the same issue on osx with node v15.14.0.
I m specifying the node version b/c the same app running on ubuntu with node v12.20.0 seems fine

[fedeee]

FYI: this also relates to: vuejs/apollo#1190

[antfu]

0.9.0 released. Would need some help to confirm if it's a fix. Thanks!

[fk1blow]

@antfu i m having @vueuse/core as a dependency so i could try that one specifically

[fedeee]

This seems to have fixed it for us

[JuroOravec]

@antfu 0.9.0 fixes the issue with vuejs/vue-apollo (vuejs/apollo#1190), thanks!

This error is coming back after upgrade to the latest

[Muchmorepig]

I met the same issue:

[jzs11]

Try this - vueuse/vueuse#718 (comment) it works for me
