Describe the Bug

npx --no-install next info

Expected Behavior

I expected the logs to give accurate information regarding the environment variable loaded.

The logs give misleading information.

I used dotenv-cli to provide a env.staging file for env variables to the command next dev. The env.staging file was successfully loaded. The info logs are copied below:

daniel (main) $ yarn dev
yarn run v1.22.5
$ dotenv -e .env.staging -- next dev
ready - started server on 0.0.0.0:3000, url: http://localhost:3000
info  - Loaded env from /path_to_project/.env.local

*EDIT: It seems codesandbox is messing with the env variables, so there's not much to see there.

To Reproduce

1. Create a project
2. Add env.local with a value, for example MESSAGE=local
3. Add env.staging with the same key but different value. For example MESSAGE=staging
4. Install dotenv-cli to be able to provide env.staging as env variable files
5. In package.json, replace the dev command with dotenv -e .env.staging -- next dev
6. Run yarn dev
