Trying to require CrestApps in a newly created Laravel project, gives me the following msg:

Answer 1

As per Composer version 2 changes regarding psr-4 autoloading standards, file SqlServerParser.php file had to be changed as follows:
line:
namespace CrestApps\CodeGenerator\DatabaseParser;
to be changed to:
namespace crestapps\laravelCodeGenerator\src\DatabaseParser;
Issue solved. Command "composer require crestapps/laravel-code-generator --dev" does not give any errors anymore, generating optimized autoload files successfully.
