Megento 2: The autoload error

Question

I have installed Magento on a test Ubuntu 20.04.01 server via composer with the command:

composer create-project --repository=https://repo.magento.com/ magento/project-community-edition ~/magento --ignore-platform-reqs

After the installation, I created a symbolic link:

sudo ln -s /home/<loginname>/magento/vendor/magento/magento2-base /var/www/html/magento

When starting Magento, I receive an autoload error:

We can't read some files that are required to run the Magento application. This usually means file permissions are set incorrectly.

However, the file permissions have been set with the following command:

sudo find . -type f -exec chmod 644 {} \;
sudo find . -type f -exec chown www-data:www-data {} \;
sudo find . -type d -exec chmod 755 {} \;
sudo find . -type d -exec chown www-data:www-data {} \;
sudo find ./var -type d -exec chmod 777 {} \;
sudo find ./pub/media -type d -exec chmod 777 {} \;
sudo find ./pub/static -type d -exec chmod 777 {} \;
sudo chmod 777 ./app/etc
sudo chmod 644 ./app/etc/*.xml

On Magento 2 : getting Autoload error the user Sinisa Nedeljkovic wrote that it might be possible that the app/etc/vendor_path.php file is missing.

If you take a look at vendor/magento/magento2-base/app/autoload.php, you'll notice following piece of code:

define('VENDOR_PATH', BP . '/app/etc/vendor_path.php');

if (!file_exists(VENDOR_PATH)) {
    throw new \Exception(
        'We can\'t read some files that are required to run the Magento application. '
         . 'This usually means file permissions are set incorrectly.'
    );
}

That means that either you don't have app/etc/vendor_path.php file, or you're not having enough permissions.

And that is the case: that file is not present in the given folder.

So my question is: how do I get that file? Or copy it from ./vendor/magento/magento2-base/dev/tests/integration/testsuite/Magento/Framework/Composer/_files/vendor_path.php?

Feedback is appreciated and with kind regards, TheStingPilot

Answer 1

I have chosen a different approach. I downloaded the tar.gz file, extracted it to \var\www\html\magento and run the installer.

It is not the easiest installation method.

Thanks for your help @BartZalas.
