 !     Push failed

Deploying with prod environment works fine though.

[rendyep]

This issue affects me too. Did you solve this problem?

[rendyep]

I think it's documented here: https://devcenter.heroku.com/articles/getting-started-with-symfony#configuring-symfony-to-run-in-the-prod-environment

If you don’t explicitly configure the environment (dev, prod etc) to use, Symfony will, by default, use the dev environment in console commands and at runtime. That would break the build, because in dev environments, Symfony uses the SensioGeneratorBundle to perform certain tasks, but that bundle is not installed upon a push - Composer does not install dev packages when pushing to Heroku.

[stof]

If you want to be able to use the Symfony dev env in the deployed version, you will indeed need to move the necessary dependencies to normal requirements rather than dev requirements.

Note however that deploying the Symfony dev environment in a world-accessible deployment is a security issue, because development tools like the WebProfiler can be revealing sensitive info (they are meant to help debugging and so expose lots of info). You should definitely not be using the dev environment on heroku. It is meant for usage on your dev setup locally.

[javiereguiluz]

Closing it as fixed by #399. A new version of the Symfony Demo app has been tagged, so it'll be available via symfony demo command in a few hours.

[bocharsky-bw]

@javiereguiluz Actually, #399 does not fix this issue, this one is a bit different. I reused @stof #398 (comment) here and sent another PR #402 to make things clearer. What do you think?

! WARNING: A Composer script terminated with an exception
! ERROR: Dependency installation failed!

!
! Typical error cases are out-of-date or missing parts of code,
! timeouts when making external connections, or memory limits.

! Check the above error output closely to determine the cause of
! the problem, ensure the code you're pushing is functioning
! properly, and that all local changes are committed correctly.
