php artisan: "failed to open stream: No such file or directory" – Debian

I just started to learn php/laravel by following some guides and tutorials, which led me to run a server using php artisan serve command.

The steps I took are as follows:

  1. install laravel using composer and adding it to $PATH.
  2. creating a project by using laravel new new-blog
  3. changing directory into the project foler and running php artisan serve command.

However, instead of the expected output of a php server with an address I get this error:

PHP Warning:  require(/home/sflash/Documents/php/laravel/new-blog/vendor/autoload.php): failed to open stream: No such file or directory in /home/sflash/Documents/php/laravel/new-blog/artisan on line 18
PHP Fatal error:  require(): Failed opening required '/home/sflash/Documents/php/laravel/new-blog/vendor/autoload.php' (include_path='.:/usr/share/php') in /home/sflash/Documents/php/laravel/new-blog/artisan on line 18

I am on a linux machine (debian buster). The structure of my project folder is like below:

app        composer.json  package.json  README.md  server.php  webpack.mix.js
artisan    config         phpunit.xml   resources  storage
bootstrap  database       public        routes     tests

As the error code above states, I don’t have a file called vendor/autoload.php. How does this occur/how to fix this?

    you don’t have vendor folder in you project
    you need to re-install laravel & then try install it using

    laravel new project or composer create-project ---prefer-dist laravel/laravel blog

    You have done everything correctly except you forget to add the vendor folder into your project directory,
    just try

     composer i

    Inside the project directory from the terminal, will solve your error. And if you get any other error then remove the composer.lock file and then try again.

    UPDATE:

    Instead of deleting the composer.lock file when facing issues like PHP version mismatch or dependency version locked just use

    composer update

    This is caused because you’re missing your "Vendor" directory which is causing a missing dependency error. To fix this you need to run:

    Composer update

    In most cases, updating the Composer will regenerate the vendor folder and the autoload.php file.

    Alternatively, you can regenerate the autoload.php file using the command,

    composer dump-autoload

    If the Composer is found corrupted, uninstall the existing one and reinstall it. To install Composer, run this command in the root project folder:

    Composer install

    You have to add vendors directory first by running the install command for the composer:

    composer install

    After that update your composer packs:

    composer update

    At the end run your migration command

    php artisan migrate
php artisan serve

    All those solutions work if the dependencies have been downloaded.

    I ran to a similar issue but with the Composer Update and/or composer i CLI solutions didn’t work because there were files/dependencies missing or unable to be located.

    I figured out that I required laravel in my project like so : composer global require laravel/installer and so the above solutions wouldn’t be able to work. So I ran

    composer help

    and it led me to use the

    composer u

    and it downloaded all the required dependencies necessary.

    then the

    php artisan serve

    command worked as expected.

    Does this problem arise when you try to clone a project from GitHub? if true, then make sure the laravel installation on your device is correct by creating a local laravel project first. if the local project runs well, then you can proceed with cloning the project from the repository.
    after cloning project, duplicate file .envy.example and rename one of them to .envy then run composer update after that php artisan key:generate then you can try php artisan serve again.

    This error can also be caused by not (manually) updating section "files" in composer.json, i.e.:

    "files": ["app/Some/Stucked/Refactored/Old/Location.php",
          "app/Some/Good/Location.php"],

    Then:

    composer update
