When I run: yarn create nuxt-app I see in package.json:

"dependencies": {
   "nuxt": "^2.15.8",
   "vue": "^2.7.10",
},

I need to use Vuex. For this environment I have to use Vuex 3. So I did what the documentation said: yarn add vuex. But this always results in installing vuex 4:

"dependencies": {
   "nuxt": "^2.15.8",
   "vue": "^2.7.10",
   "vuex": "^4.1.0"
},

But this will cause various problems, because vuex 4 only works with Vue 3.

The result of running yarn add vuex is the same as running yarn add vuex@next --save.

How do I install Vuex 3 for Vue 2.7 in my Nuxt project? What did I miss?
