I have written a plugin for CakePHP 3.4.* version and uploaded to GitHub.
I have also created repository with packagist
Now when I run
$ composer require cakephp-app-installer/installer
it gives the error bellow:
Using version ^1.0 for cakephp-app-installer/installer
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.
Problem 1
- Can only install one of: cakephp/cakephp[3.4.0, 3.4.6].
- Can only install one of: cakephp/cakephp[3.4.6, 3.4.0].
- Can only install one of: cakephp/cakephp[3.4.0, 3.4.6].
- cakephp-app-installer/installer v1.0.0 requires cakephp/cakephp 3.4 -> satisfiable by cakephp/cakephp[3.4.0].
- Installation request for cakephp-app-installer/installer ^1.0 -> satisfiable by cakephp-app-installer/installer[v1.0.0].
- Installation request for cakephp/cakephp (locked at 3.4.6, required as 3.4.*) -> satisfiable by cakephp/cakephp[3.4.6].
Installation failed, reverting ./composer.json to its original content.
My composer.json file looks like:
{
"name": "cakephp-app-installer/installer",
"description": "GUI Installer plugin for CakePHP",
"type": "cakephp-plugin",
"require": {
"cakephp/cakephp": "^3.4"

Testing on freshly created cakephp application with 3.4.6 version.
Couldn't understand, why it is not working.
