The official documentation can be found here.

Why do I get "Class "MagentoBackendAppRequestPathInfoProcessorProxy" does not exist" when I install Magento 2?

I started to install Magento. This is the command line instruction:

"php bin/magento setup:install --base-url="http://localhost/magento" --db-host="localhost" --db-name="magento" --db-user="root" --db-password="" --admin-firstname="admin" --admin-lastname="admin" --admin-email="[email protected]" --admin-user="admin" --admin-password="admin123" --use-rewrites="1" --backend-frontname="admin"

When I execute it, I have this error:

Class "MagentoBackendAppRequestPathInfoProcessorProxy" does not exist

How can I reslove this problem?

    This error is coming when there is some permission related issue, so try to provide appropriate permissions to Magento folder & files.

    For permission cmd, you can follow below commands :

    cd <your Magento install dir> 

// 644 permission for files
find . -type f -exec chmod 644 {} ; 
                   
// 755 permission for directory
find . -type d -exec chmod 755 {} ;    

chmod 644 ./app/etc/*.xml

chown -R :<web server group> .

chmod u+x bin/magento

    In my case it was php version issue.

    I was running command

    php bin/magento s:up

    which give me below error

    Class "MagentoBackendAppRequestPathInfoProcessorProxy" does not exist

    because my default php version was set 8.0 for command line so i need to use

    /usr/bin/php7.4 bin/magento s:up

    This happened to me after updating to Magento 2.4.4. I fixed it by running:

    composer dump-autoload
