Question

getting a weird error when I try to build project on droplet

Posted December 8, 2017 7.6k views
PHPUbuntu 16.04

On my development environment I would usually run these commands to rebuild my project:

php artisan cache:clear
composer dump-autoload

but when I try running them on my droplet I get some weird errors:

PHP Fatal error:  Uncaught Error: Class 'Illuminate\Foundation\Application' not found in /var/www/dev.drmanansala.com/bootstrap/app.php:14
Stack trace:
#0 /var/www/dev.drmanansala.com/artisan(18): require_once()
#1 {main}
  thrown in /var/www/dev.drmanansala.com/bootstrap/app.php on line 14

Cannot create cache directory /home/francis/.cache/composer/files/, or directory is not writable. Proceeding without cache

Your environment isn’t configured correctly. You probably need to remove the contents of vendor/ from your version control and run composer install on your droplet.

    Thanks for the response! I have my repo ignoring my vendor folder already. I tried doing composer install and running into some problems. I’m guessing the machine’s php also needs to be updated? This is the message i get when trying to do composer install:

    Cannot create cache directory /home/francis/.composer/cache/repo/https---packagist.org/, or directory is not writable. Proceeding without cache

  Problem 1
    - Installation request for laravel/framework v5.3.31 -> satisfiable by laravel/framework[v5.3.31].
    - laravel/framework v5.3.31 requires ext-mbstring * -> the requested PHP extension mbstring is missing from your system.

    - phpunit/phpunit 5.7.25 requires ext-dom * -> the requested PHP extension dom is missing from your system.

  To enable extensions, verify that they are enabled in those .ini files:

    - /etc/php/7.0/cli/conf.d/10-opcache.ini

    - /etc/php/7.0/cli/conf.d/20-tokenizer.ini
  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

ran a few commands:

sudo apt-get install php-xml
sudo apt-get install php-mbstring

was able to get my composer install to work. Laravel is finally running but it’s running into problems lol. I’m guessing it’s a problem with the directories now

Old Question, but ran into this problem. Fixed by doing this:

sudo apt-get install php7.0-gmp
sudo apt-get install php-curl

then restart the server.
