PHP Fatal error

henkschaap

Hello all, I try to install Flarum on Ubuntu 20.04. In the last step, trying to load the website in a browser, I get an index page of the flarum folder. From /var/log/apache2 I learned that php encountered a fatal error:

PHP Fatal error: require(): Failed opening required '/var/www/html/flarum/vendor/autoload.php' (include_path='.:/usr/share/php') in /var/www/html/flarum/site.php on line 22

Then the file site.php says on line 22:

require` DIR.'/vendor/autoload.php';

I could not find any autoload.php on my system.

Any help is appreciated.

Kind regards

henkschaap how did you install flarum? Did you use composer? It seems you haven't ran any composer commands yet..

Hi luceos, Yes I used composer. I ran the following command in the directory /var/www/html/flarum:

composer create-project flarum/flarum . --stability=beta

luceos

henkschaap can you confirm the vendor folder exists in that directory?

henkschaap

luceos No vendor folder is present. The content of /var/www/html/flarum is:
-rwxr-xr-x 1 www-data www-data 701 mei 6 10:57 CHANGELOG.md
-rwxr-xr-x 1 www-data www-data 1990 mei 6 10:57 composer.json
-rwxr-xr-x 1 www-data www-data 265 mei 6 10:57 extend.php
-rwxr-xr-x 1 www-data www-data 634 mei 6 10:57 flarum
-rwxr-xr-x 1 www-data www-data 1168 mei 6 10:57 LICENSE
drwxr-xr-x 3 www-data www-data 4096 mei 6 10:57 public

drwxr-xr-x 10 www-data www-data 4096 mei 6 10:57 storage

FYI: For installing Flarum, I followed this guide: https://www.howtoforge.com/tutorial/ubuntu-flarum/. Exceptions: I use Ubuntu 20.04 and PHP7.4; I did not use sudo in the composer command.

henkschaap the create-project command probably didn't exit successfully if you don't have a vendor folder.

You can run composer install inside of the directory that contains composer.json to install the missing vendor folder. Or you could try starting over and see what the create-project command tells you.

Maybe it's exiting early due to a limited execution time.

clarkwinkelmann Yes..., you are right. I did 'composer install' again and found out from the begin of the output on the terminal that php7.4-curl was missing! After installing that module 'composer install' was not able to write the vendor directory which made sense because the owner of the directory flarum is www-data. After temporarily making the directory writable I could run 'composer install' and finish successfully!

Great! Issue resolved. Thank you guys for the quick and knowledgeable support.
BTW I am impressed by the simplicity and elegance of flarum

I am getting the same error after installing flarum on my website https://linuxbuz.com.

PHP Fatal error: require(): Failed opening required '/var/www/html/flarum/vendor/autoload.php' (include_path='.:/usr/share/php') in /var/www/html/flarum/site.php on line 22

HiteshJethva sounds like the composer installation failed. Make sure it successfully completed.
