Trick vue-apollo 4 to think it's working on a Vue3 project

[smolinari]

Hi,

I think vue-demi isn't working right. I'm building an app extension for Quasar, where vue-apollo is a dependency of the extension and it seems vue-apollo thinks it's working with Vue2. I'm getting these warnings.

 warning  in ./node_modules/@quasar/quasar-app-extension-apollo-v2/node_modules/@vue/apollo-composable/node_modules/vue-demi/lib/v2/index.esm.js

"export 'default' (imported as 'Vue') was not found in 'vue'

 warning  in ./node_modules/@quasar/quasar-app-extension-apollo-v2/node_modules/@vue/apollo-composable/node_modules/vue-demi/lib/v2/index.esm.js

 warning  in ./node_modules/@quasar/quasar-app-extension-apollo-v2/node_modules/@vue/apollo-composable/node_modules/vue-demi/lib/v2/index.esm.js

 warning  in ./node_modules/@quasar/quasar-app-extension-apollo-v2/node_modules/@vue/composition-api/dist/vue-composition-api.esm.js

 warning  in ./node_modules/@quasar/quasar-app-extension-apollo-v2/node_modules/@vue/apollo-composable/node_modules/vue-demi/lib/v2/index.esm.js

"export 'default' (reexported as 'Vue') was not found in 'vue'

And when the app runs, I get this error.

index.esm.js?e1db:9 Uncaught (in promise) TypeError: Cannot read property 'version' of undefined

and it comes down to this line:

import Vue from 'vue'
import VueCompositionAPI from '@vue/composition-api'

if (Vue && !Vue['__composition_api_installed__'])
  Vue.use(VueCompositionAPI)

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

But, I'm definitely using Vue3 (assuming the code above is pointing at a Vue2 implementation).

Anyone have a clue how to fix this?

Ok. I was using TypeScript. Went to a non-typescript project and at least the app compiles now. I guess this is TypeScript incompatibility?

I'm past this now. Just not using TypeScript.....
