The Problem:
After cloning the Joomla-cms repository, running composer install and npm ci, I get the error message ‘Failed opening required ‘
The Solutions:
Solution 1: Check File Permissions
The issue arises when the folder containing the Joomla repo is owned by a different user than the one trying to access the site through the browser. This user mismatch prevents the generation of the autoload_psr4.php file. To resolve this, use the following command:
sudo chown -R [your_username]:www-data [folder_path]
Replace [your_username] with your actual username and [folder_path] with the path to the Joomla repo folder. This command changes the ownership of the folder and all its contents, allowing the file to be created during the request from the browser.
Q&A
Why am I getting an error about a missing autoload_psr4.php file when installing Joomla?
Check the permissions of the folder. The file may not be able to be created due to insufficient permissions.
What is a sudoer user?
A sudoer user is a user who has permission to run commands as another user, typically the root user.
