[2476] Add webpack plugins error

I try to use two ways

const px2Rem = require('px2rem-webpack-plugin')
build: {
        plugins: [
            new px2Rem({originScreenWidth: 375})
        ]
    }

or

build: {
        extend(config, { isDev, isClient }) {
            if (isClient) {
                config.plugins.push(new px2Rem({originScreenWidth: 375}))
            }
        }
    }

but, compile error

ERROR  Failed to compile with 1 errors  

This dependency was not found:

* /Users/zc/code/exercise/vue-ssr/.nuxt/client.js in multi webpack-hot-middleware/client?name=client&reload=true&timeout=3000&path=/__webpack_hmr ./.nuxt/client.js

To install it, you can run: npm install --save /Users/zc/code/exercise/vue-ssr/.nuxt/client.js

This is a webpack plugin that turns px to rem and how should I use it
