Cannot find module 'vuetify-loader/lib/plugin'

I've got the same issues while creating new Vuetify app by official guide.

After adding vuetify: vue add vuetify
The missing step was installing new npm dependencies with: npm install

Later I run npm run serve and it started succesfully.
There is an issue in the documentation!

Try to manually install the package:

npm install vuetify-loader -D

you should check the vue-loader plugin path. in my case it is:

vue-loader/dist/plugin

Run npm cache clean --force. It should clear your npm cache. For reference: https://github.com/npm/npm/issues/19072#issuecomment-345555468

I had the same problem. This whole thing worked out for me.

1. vue create your-app
2. cd your-app
3. npm i --save-dev --no-optional vuetify-loader vue-cli-plugin sass node-sass sass-loader
4. npm i
5. vue add vuetify

I know this looks redundant but it worked.

I got the same error when I cloned a repository and I installed the dependencies only on the master branch. When I switched to a different branch (git checkout different_branch) I forgot to install the dependencies there. So make sure you installed the dependencies before you launch the server.

Just had the same problem. In my case it was caused by placing the file vue.config.js in the top-level-folder (next to package.json) instead of in the 'src' folder. Obviously there might be many reasons for this error, but maybe it helps someone...

do a npm install after adding vuetify as vue add vuetify then start server by npm run serve

In your package.json: move @nuxtjs/vuetify from devDependencies to dependencies

just install the pacakge to devDependencies:

npm i --save-dev vue-loader-v16

After installing the dev dependency

npm run serve
