Have you included this line in .env.staging?:

NODE_ENV=production

[AmosXu]

@sodatea no

Then add it.
NODE_ENV=production is required for packaging purpose.

Why staging must be a production?
If I need dev-tools on stage, it would be disabled with NODE_ENV=production

[haoqunjiang]

@vagrantir If you need devtools, add Vue.config.devtools = true to main.js.
