Reproduction

https://stackblitz.com/edit/nuxt-starter-qwahbu?file=package.json

Describe the bug

I have 2 environment files .env and .env.prod. According to the docs, I can pass the --dotenv flag to specify a different env file to load for nuxt preview command - https://nuxt.com/docs/api/commands/preview

But it does not seem to work.

I have tried multiple variants of this and it always loads the .env file and not my .env.prod file.

Here is what I tried (see reproduction):

+ "preview": "nuxt preview --dotenv .env.prod"
+ "preview": "nuxt preview --dotenv=.env.prod"
+ "preview": "nuxt preview --dotenv prod"

Nothing worked.

I have just experienced the same (with Nuxt 3.10.3 as well as 3.11.2).

Doc says it should work (https://nuxt.com/docs/api/commands/preview)

But my terminal even says it's just going to load .env

I hope this helps possibly locate the issue.

Been going mad experiencing the exact same issue. Nuxt 3.13.2.

Same problem here, any updates?

As a workaround, read in the .env variables as you'd have to on the server 👍🏻

3fe1ff9 only appears to fix the console message, which is great, but doesn't address the reported issue (nuxt preview does not respect the --dotenv option ). Can we re-open this?

Would you provide a reproduction of it not working? It works fine for me - including in the originally provided stackblitz:

[dixhuit]

Ah, the original stackblitz repro is also working for me (first time trying it I'll admit). Hmm, need to double check my local project now...

[dixhuit]

Yep, not sure where the confusion stems from but my local project is behaving as expected now. Apologies for the noise.
