Migration Problem with laminas/laminas-developer-tools

Problem 1

  • Installation request for laminas/laminas-developer-tools dev-master -> satisfiable by laminas/laminas-developer-tools[dev-master].
  • Can only install one of: laminas/laminas-servicemanager[3.3.x-dev, 2.4.13].
  • laminas/laminas-developer-tools dev-master requires laminas/laminas-servicemanager ^2.7.5 || ^3.0.3 -> satisfiable by laminas/laminas-servicemanager[3.3.x-dev].
  • Installation request for laminas/laminas-servicemanager 2.4.13 -> satisfiable by laminas/laminas-servicemanager[2.4.13].

Welcome to the forums! :smiley:

dev-master irritates me here. Which installation command for the Composer do you use?

Compare with the descriptions in the repository:

composer require --dev laminas/laminas-developer-tools
