Hi there!

I want to use php in jupyterlab, but I encountered the following problem during the installation process. Does anyone know how to solve this?
Thank you very much.

I don't know if you solved it, jupyter-php-installer\src\Installer\Installer.php line 150 --name=jupyter-php-instance modified to --name=litipk/jupyter-php-instance, I After the change it installed properly
