};

also do suggest me how to setup a project safely with vuex and vue-router

Answer 1

Try to just install the pacakge to devDependencies:

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

It helped me out.

With babble.config.js do you then mean babel.config.js , hehe? Anyhow, I think your babel.config.js should just be like this:

module.exports = {
    presets: ["@vue/cli-plugin-babel/preset"],
};

And for keeping your package.json more clean, you could make an .eslintrc.js file instead - just copy/paste the data from your eslintConfig key in package.json

Answer 2

Update npm to version higher than 6.9 and do a npm i , this should install the missing packages https://github.com/vuejs/vue-cli/pull/5718

npm install npm@latest -g (To update npm)

Answer 3

I solved it reinstalling the package. First you need to uninstall it

npm uninstall vue-loader-v16

Once uninstall completes, install it again

npm i vue-loader-v16

It seems obvious but it worked twice for me

Answer 4

For others, in case the other answers didn't work, I found my npm version was in need of an update.

Answer 5

You need to delete node-modules folder from your project. Then you install npm again by using command

npm i -g npm

Then you need to serve your application as

npm run serve

This might be helpful to you.

Answer 6

This happens when you are using a lower version ( < 6.9) npm, so, are you using a lower nodejs?

1. check your node version ( means your npm version)

node -v

2. install a newer node version

nvm install 14.xx

3. nvm use 14.xx

npm -v => 6.14.x

Answer 7

Actually downgrading the vue/cli from 4.5.6 to 3.0.1 worked..it downgraded the vue cli from 3 to 2...actually vue cli 3 is beta version....shouldn't use 3 right now...the comnand i used to downgrade You simply need the specific version you want to install..in my case ->

npm install -g @vue/cli@3.0.1

Answer 8

Edit App.js >> Go to file path: src/component/App.vue

import this code

// code returned from the main loader for 'source.vue'

// import the <template> block
import render from 'source.vue?vue&type=template'
// import the <script> block
import script from 'source.vue?vue&type=script'
export * from 'source.vue?vue&type=script'
// import <style> blocks
import 'source.vue?vue&type=style&index=1'

script.render = render
export default script

and after run

npm run serve

i hope solve this error "Cannot find module 'vue-loader-v16/package.json'"
