ClassNotFoundError with Composer install --no-dev in symfony

Question

I am trying to upload my symfony project to the server but passing it to dev gives me this error.

composer install --no-dev --optimize-autoloader

Script @auto-scripts was called via post-install-cmd

In the Symfony documentation it says to run export APP_ENV = prod but it puts me that the term 'export' is not recognized as the name of a cmdlet

`export` is a [`bash` thing](https://stackoverflow.com/questions/61820244#comment109345716_61820244). Either your `.env` file is not configured and is defaulting to the `dev` environment, or the bundles are incorrectly configured (unlikely, since flex should take care of it). Try running `composer dump-env prod` first and try again. And check `config/bundles.php` and search for `MakerBundle` to see in what envs it's active. — msg, May 20 '20 at 18:33
I've run `composer dump-env prod` and perfect, but running `composer install --no-dev --optimize-autoloader` gives me this error: In AbstractMySQLDriver.php line 106: !! !!

Check your environment variables, specially `DATABASE_URL`. Your server doesn't accept connections from the configured interface, maybe try `localhost` or contact support. — msg, May 21 '20 at 10:32
What have you tried to debug the problem? Looks like your kernel tries to run some bundle that has not been installed — Nico Haase, May 21 '20 at 12:14

Following up on @Reknil's answer, which put me on the right path:

For bash on OSX, this worked:

$ APP_ENV=prod composer install --no-dev

My .env file had APP_ENV=dev, so adding the APP_ENV=prod overrides the environment just for that command.

For PowerShell, I'm not sure how to set the environment var just for a single command. This SO post has some options.

Cheers, jz

fyi, if I run without the APP_ENV=prod, I get the following:

$ composer install --no-dev

Check you file .env: Must be: APP_ENV=prod

So, make sure, you environments must be PROD mode

Also you can check environments on you WEB Server. For example you environment variables can provide by Nginx (fastcgi_param APP_ENV prod) In any case, the problem is that the environment is not PROD – Reknil Linker May 20 '20 at 12:29
