How to run composer with different PHP versions in Cpanel?

Question:

When we try to run a composer command, like update, we usually do the following:

composer update

Cpanel has multiple PHP binaries, but in this case, we are unable to select a specific PHP binary to use, instead we have to run it with the default one, how to run composer update with a different php binary in cpanel?

Solution

composer binary file, is a phar file. PHAR is necessarily a PHP Archive and usually automatically detect the running php. But as it is essentially written in php, you may explicitly run it with a different php binary, if you want. To run composer with different php binary, first, you need to find the location of composer. You may do so, using the following:

[email protected] [~]# which composer
/opt/cpanel/composer/bin/composer

Cpanel different php binaries are available under the following kind of directory:

/opt/cpanel/ea-phpXX/usr/bin/php

XX is the version number of PHP. So for example if you need to use PHP 7.4, you would need to run using the following:

/opt/cpanel/ea-php74/usr/bin/php

Now, to run composer update along with PHP 7.4 binary, you may do something like the following:

/opt/cpanel/ea-php74/usr/bin/php /opt/cpanel/composer/bin/composer update

First, make sure you are in the directory where you want to install laravel, for example, something like the following:

cd /home/username/public_html

Then, you may run the above command:

/opt/cpanel/ea-php74/usr/bin/php /opt/cpanel/composer/bin/composer update
or in case, you want to to install
/opt/cpanel/ea-php74/usr/bin/php /opt/cpanel/composer/bin/composer install
or may be, you wan to run update with no-scripts
/opt/cpanel/ea-php74/usr/bin/php /opt/cpanel/composer/bin/composer update --no-scripts

Uncaught ErrorException: require(/home/username/public_html/vendor/composer/../../app/Helpers/helper.php): failed to open stream: No such file or directory in /home/username/public_html/vendor/composer/autoload_real.php:71

Error Details

While trying to run any of the following with Laravel composer installer, you see an error similar to the following:

Uncaught ErrorException: require(/home/username/public_html/vendor/composer/../../app/Helpers/helper.php): failed to open stream: No such file or directory in /home/username/public_html/vendor/composer/autoload_real.php:71

How to fix this?

Solution

The error is appearing, most likely you forgot to add the ‘app’ directory of laravel in your root directory. Make sure, you have the ‘app’ directory in your root directory, then run any of the following:

If this is the first time, you need all laravel packages, run:

composer install

If this is not the first time, you may run the following:

composer update

Good luck.
