can you guys explain me meaning of error myVersions

CodePudding user response：

As you are seemingly on an old version of npm (<=6.x) you need to install the peer dependency yourself:

npm i -D @vue/[email protected]

After installing the dependency, edit your package.json and insert this block on the top level, right after the "devDependencies" object:

"peerDependencies": {
    "@vue/cli-service": "^5.0.0"
}

and remove that dependency from the "devDependencies" object.

If you don't want to deal with peer dependencies yourself, upgrade your node and npm version. To upgrade npm only:

npm i -g npm

Despite the fact that I reconfigured entire project. I will anyway answer this question.

Issue was related to cli-service 5.0.0, when I should have had 5.0.8 in order to use babel 5.0.0.

I want to add that if you use default vue.2 template with vue/cli 5.0.8, You will get another error after installing vuetify, which was not able to fix.

Error is related to vuetify loader. I fixed it with start up new project and manually inserting all dependencies compatible with vuetify-loader 1.5 Because 1.7 brakes npm run serve
