Issue

I tried to install CodeIgniter through composer using this:

composer require bcit-ci/CodeIgniter

And it installed successfully I got a warning, see screenshot

And then I tried to install with this:

composer require codeigniter/framework

and I got a fatal error, see screenshot here

I don't know what I am doing wrong.

Solution

this is weird that composer trying to install the very first package 1.0.0 , works perfectly at my side.

however , you will need to pass the package version statically as follows:

composer require codeigniter/framework:"3.1-stable"

this will often -till the answer date- install 3.1.0 version,

you may try to download the latest version :

composer require codeigniter/framework:"3.1.4"
