OK people!!!
I’ve found a solution(trick). Off course it is a trick the way I see it but it is working absolutely fine to me. Remember this error happened to me due to upgrade from vuetify 1.5 to 2.1….
Steps I took were,

  • Created a new project(name = candy) with latest Vue and Vuetify.

  • Installed all dependencies and devDependencies in this new project(candy in my case) which I had in my original projects package.json file.

  • You can open package.json file of your original project and terminal in new project(candy) and run commands yarn add "package name in original project or npm install "package name.

  • Then copied this(candy) package.json file and pasted it in my original project folder and renamed these files and folder to old.

  • File & folder == node_modules to node_modules_old, package.json to package_old.json, vue.config.js to vue.config_old.js, yarn.lock to yarn_old.lock.

  • Copy only package.json of candy project to the original project’s folder.

  • Run command yarn install or npm install.

  • And the server runs now.

Further, you will have to set your code according to the project. It can be in vue.config.js mostly or in babel config file or webpack.config.js.
