Error: Cannot find module 'nuxt-i18n' and docker-compose up does not start

Question

What I want to solve

I'm using docker-compose with Nuxt front and Rails for the backend, and when I tried to use Jest for testing Nuxt, I found that I needed to switch versions. So I changed from node:14.4.0-alpine to node:14.15.5-alpine and tried to install Jest, but I got a nuxt-i18n' error when building node:14.15.5-alpine'. I removed 'nuxt-i18n' from the package.json file. The build of node:14.15.5-alpine was successful and the installation of Jest was completed, but the next time I used the docker-compose up command, I got an error. What should I do in this case?

Answer 1

I thought it was a glitch that had been caused by the upgrade, but this time the error was caused by the i18n settings in nuxt.config.js. After commenting it out, the docker command started as usual.

Code

nuxt.config.js

  // Doc: https://nuxt-community.github.io/nuxt-i18n/basic-usage.html#nuxt-link
  // i18n: {
  //   locales: ['ja', 'en'],
  //   defaultLocale: 'ja',
  //   vueI18n: {
  //     fallbackLocale: 'ja',
  //     silentFallbackWarn: true,
  //     messages: {
  //       ja: require('./locales/ja.json'),
  //       en: require('./locales/en.json')
  //     }
  //   }
  // },
