if you are on windows open the folder and give permissions to generated folder to "uncheck" read only and for linux operating systems use chmod -R 755 generated and you will be able to install the magento 2.3.1


You must set the permission for project and you can do it with you must click right to folder project and unchecked the "Read-only" for all files and folders from project.

  • I have done that, but that is not unchecking. When process done, that seems again checked. Can you suggest me that why is it happening?
