Laravel/Lumen - Missing Commands In Artisan Console

I have a problem with runing Laravel's Artisan. There are most of the commands missing. Everything worked fine till the last composer/code update.

For an example if I write php artisan migrate, I get following error: Command "migrate" is not defined.

Below is an example of output that I get by typing php artisan.

Laravel Framework version Lumen (5.1.6) (Laravel Components 5.1.*)

  command [options] [arguments]

  -h, --help            Display this help message
  -q, --quiet           Do not output any message
  -V, --version         Display this application version
      --ansi            Force ANSI output
      --no-ansi         Disable ANSI output
  -n, --no-interaction  Do not ask any interactive question
      --env[=ENV]       The environment the command should run under.
  -v|vv|vvv, --verbose  Increase the verbosity of messages: 1 for normal output, 2 for more verbose output and 3 for debug

Available commands:
  help          Displays help for a command
  list          Lists commands
  serve         Serve the application on the PHP development server
  schedule:run  Run the scheduled commands

Does anyone have any ideas how to fix this?



It seems there was a problem with composer. Somehow composer.lock got into git ignore list and libraries used on production were different than the ones used in development.
