installation problem for v4.4.8

Im using composer to install previous version

Code:

composer create-project codeigniter4/appstarter:4.4.8 myproject

After that I'm running this command

Code:

php spark env development

and get this error

This "system/bootstrap.php" is no longer used. If you are seeing this error message,
the upgrade is not complete. Please refer to the upgrade guide and complete the upgrade.
See https://codeigniter4.github.io/userguide...e_450.html
PHP Fatal error: Uncaught Error: Undefined constant "ENVIRONMENT"

Then I manually created the .env file.

But the error is still there.

Please help
