What you did:

Try to install vuex-persistedstate with a vue-cli created package.json, nothing special, with:

npm install vuex-persistedstate

What happened:

npm gave the following error:

Problem description:

npm can not resolve the peer dependency vuex@"^3.0 || ^4.0" of vuex-persistedstate eventhough I have a vuex ^4.0 version installed.

Is there a way to install it without using --force or --legacy-peer-deps?

Same problem, bypassed it temporarily with: https://github.com/robinvdvleuten/vuex-persistedstate/pull/374/files by updating the version in peerDependencies. I don't think that style of dependency specification supports anything other than versions with numbers? That's just a guess, I don't know npm that well. I think it has to be parseable which semver, but I don't think the style vuex is using is. https://github.com/npm/node-semver
