Cloudfoundry Laravel "Could not open input file: artisan"

Question

I am trying to push a Laravel application with the CF CLI. I created a new Laravel application, a manifest.yml and tried to deploy it but got the error "Could not open input file: artisan".

All I did was :

composer create-project --prefer-dist laravel/laravel app

manifest.yml
---
applications:
- name: laravel-test
  memory: 512M
  buildpacks:
    - php_buildpack_v4_6_13

cf push

Here's the result of the command :

Does anyone have any idea on how to resolve this problem ? I've searched but I didn't find it anywhere else.

Also, I can't try to change the buildpack to run some tests, custom buildpacks are not allowed where I am.

Answer 1

It looks like the error is occurring during the composer install phase when it's trying to run the post-autoload-dump event, specifically the @php artisan package:discover --ansi command. The error message indicates that it could not open the input file: artisan.

The Laravel application expects the artisan script to be present in the root directory. However, in a CF environment, the application is staged in a different directory, and the artisan script might not be accessible.

To resolve this issue, you can try the following steps:

Check Directory Structure

Ensure that the artisan script is present in the root directory of your Laravel application. When you create a new Laravel application using composer create-project, the artisan script should be automatically generated.

Modify Composer Scripts:

Update your composer.json file to include the correct paths. Open composer.json and look for the "scripts" section. It should have something like this:

"scripts": {
    "post-autoload-dump": [
        "Illuminate\\Foundation\\ComposerScripts::postAutoloadDump",
        "@php artisan package:discover --ansi"
    ]
},

Ensure that the @php artisan package:discover --ansi command is correctly pointing to the artisan script. If needed, adjust the path to match the Cloud Foundry environment.

Adjust Command in manifest.yml

You can optionally update your manifest.yml file to specify the correct start command. Instead of relying on the default command, you can explicitly define the command to run your Laravel application. For example:

applications:
  - name: laravel-test
    memory: 512M
    buildpacks:
      - php_buildpack_v4_6_13
    command: "php public/index.php" // assuming that your Laravel application's entry point is public/index.php

Redeploy

After making these changes try redeploying and this should be enough.

pardon any kind of syntax errors
