As @Seegy said,

  • Vue 3 uses Vuex 4
  • Vue 2 uses Vuex 3

As of Feb 2022,

  • If you are using Vue 2, use the following to install Vuex 3
    • npm install vuex@3.4.0 --save
  • If you are using Vue 3, use the following to install Vuex 4
    • npm install vuex --save or npm install vuex@next --save

had the same error just try npm install vuex@next --save instead of npm install vuex --save and it will work

This works for me: npm install vuex@next --save --force.

I tried this before but it didn't work for me

npm install vuex --save

So, this worked for me:

npm install vuex@next --save
