Vue + Webpack build Voir la page blanche

J'ai un problème avec l'application vue + webpack. Quand je lance npm run dev, tout s'est bien passé. Lorsque je passe en mode de production, npm run build, le processus de construction est terminé. Mais lorsque j'ouvre le fichier dist index.html ou que je copie le package fourni avec index.html dans le dossier d'hébergement partagé public_html, il n'affiche rien.

ci-dessous est ma configuration:

Mon principal suspect est que quelque chose ne va pas dans la configuration de mes ressources sur Webpack. Voici donc la structure de mes dossiers au cas où cela aiderait.

src
  assets
    styles
      main.scss
  App.vue
  main.js

Désolé avant si je ne peux pas montrer plus de code, merci.

Je suppose que vous exécutez votre production sur un sous-répertoire du dossier de projet racine, par exemple. http://example.com/folder.

Si votre projet se trouve dans le sous-répertoire folder, vous devez configurer la variable assetsPublicPath dans config/index.js pour la propriété build.

Exemple:

build: {
  assetsPublicPath: '/folder/'
}

En outre, la propriété base doit être définie sur: 

export default new VueRouter({
  base: '/folder/'
})

Voir plus ici .

Lorsque vous collectez davantage de données, il se peut que la configuration de votre hôte charge la mauvaise page.

Pour Apache, votre Alias ou vhost doit être pointé dans le répertoire dist. Par exemple (mon propre cas d'utilisation)

Alias /foo /var/www/htdocs/foo/dist

Dans mon cas, tout ce que je dois faire est d’ajouter une redirection dans router.js
{ path: "/index.html", redirect: "/" }
