Vue
Upgraded project (Vue2->Vue3) fails to build for production #13018
-
|
After following the migration guide as described in https://v3-migration.vuejs.org/ everything works fine when running the development server with 'yarn run serve'. If I try to build it for production with 'yarn build' the build fails. (see the errors in the attachments)
Hope that someone can help me with this. Best regards, |

It looks like it's failing because you're using a version of ESLint that's too new. I believe the It will build if you skip ESLint, e.g. by changing the "build": "vue-cli-service build --skip-plugins @vue/cli-plugin-eslint",To get ESLint working, I suggest creating a new project using Vue CLI and copying the dependency versions from that. Longer term you'll likely want to make the switch to Vite. |
