How do i install older version of CI4 using composer

That applet intentionally locks composer.json to the requested version. If you want to update it later you will need to modify composer.json and change the requirement back to an open-ended dependency (like `^4.1`)

Hi, Thank you for the feedback and help. This is what i did:

(1) Create a new CI4 "ci4tst" using "php ci4-install.php ci4tst 4.1.9" - successful but failed on this lines:

Code:

cd ci4tst; composer require -W codeigniter4/framework:4.1.9
The system cannot find the path specified.

(2) ran the commands manually - successful
(3) ran the php spark to test - successful, shows version 4.1.9
(4) Edited composer.json as:

Code:

"require": {
        "php": "^7.3 || ^8.0",
        "codeigniter4/framework": "^4.1"
    },

(5) Delete vendor folder and ran composer install - successful
(6) Ran "composer update". Generates the following messages:

(7) Ran php spark - failed with the messages:

Any advise. We could always install the latest version and add the codes from the older version. But there are times when I find using the latest version, the apps produces different results or breaks and I need confirm that it is not due to the latest version. I hope you understand my needs.

Previously we had, i think under CI3, we could run composer to install older version and they worked fine.
