php/laravel — php 工匠服务 — opensuse 15.0 错误

Question

So I am new to php/laravel and am trying to set up my environment here with composer on opensuse 15.0.

When I try to run php artisan migrate

I get this error:

PHP Warning:  require(/home/mattyo/FirstLaravelProject/matt-project-laravel/vendor/autoload.php): failed to open stream: No such file or directory in /home/mattyo/FirstLaravelProject/matt-project-laravel/artisan on line 18
PHP Fatal error:  require(): Failed opening required '/home/mattyo/FirstLaravelProject/matt-project-laravel/vendor/autoload.php' (include_path='.:/usr/share/php7:/usr/share/php7/PEAR') in /home/mattyo/FirstLaravelProject/matt-project-laravel/artisan on line 18

I get the same error when trying to run php artisan serve .

I have tried to run composer update along with composer install composer update --no-scripts and had no luck.

Any help would be greatly appreciated.

here's my composer.json

After running composer global require laravel/installer I received the following error message:

Changed current directory to /home/mattyo/.config/composer
Using version ^3.0 for laravel/installer
./composer.json has been updated
Running composer update laravel/installer
Loading composer repositories with package information
Updating dependencies
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - laravel/installer[v3.0.0, ..., v3.0.1] require ext-zip * -> it is missing from your system. Install or enable PHP's zip extension.
    - laravel/installer[v3.1.0, ..., v3.2.0] require php ^7.2.9 -> your php version (7.2.5) does not satisfy that requirement.
    - Root composer.json requires laravel/installer ^3.0 -> satisfiable by laravel/installer[v3.0.0, v3.0.1, v3.1.0, v3.2.0].

To enable extensions, verify that they are enabled in your .ini files:
    - /etc/php7/cli/php.ini
    - /etc/php7/conf.d/ctype.ini
    - /etc/php7/conf.d/dom.ini
    - /etc/php7/conf.d/iconv.ini
    - /etc/php7/conf.d/json.ini
    - /etc/php7/conf.d/mbstring.ini
    - /etc/php7/conf.d/openssl.ini
    - /etc/php7/conf.d/pdo.ini
    - /etc/php7/conf.d/pdo_sqlite.ini
    - /etc/php7/conf.d/phar.ini
    - /etc/php7/conf.d/sqlite3.ini
    - /etc/php7/conf.d/tokenizer.ini
    - /etc/php7/conf.d/xmlreader.ini
    - /etc/php7/conf.d/xmlwriter.ini
You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

Installation failed, reverting ./composer.json to its original content.

Answer 1

It seems the autoload.php file wasn't created by Composer for some reason. try composer dump-autoload and see if it works by running php artisan in the terminal.

If this issue still exists, remove the ./vendor directory with rm -rf vendor/* and remove composer cache composer clearcache . Then run composer install again

If none of the above solved the problem, Check if the composer.json file contains wrong or missing dependencies.
