CakePHP Install Specific Version

If you run composer help create-project it states that:-

You can also specify the version with the package name using = or : as separator.

So you can use either of the following commands (similar to installing a package with require):-

composer create-project --prefer-dist cakephp/app:3.0.0 my_app_name

Or:-

composer create-project --prefer-dist cakephp/app=3.0.0 my_app_name

You can also use * notation as a wildcard in the version number. So if you want to make sure you get all the most recent bug fixes of the 3.0.x branch:-

composer create-project --prefer-dist cakephp/app:3.0.* my_app_name

Try

composer create-project --prefer-dist cakephp/app=3.0.0 my_app_name 

that's work to me...

composer create-project --prefer-dist cakephp/app ProjectName 3.0

specify version after project name.
