Unable to install LERN 5.x package on Laravel 6.x

I am trying to install this package on Laravel 6.8 but getting following composer errors, it seems like something wrong with dependency requirements

Using version ^5.0 for tylercd100/lern
./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.

Answer 1 · 2020-02-06T11:19:43.000Z

This is due to a conflict in requires.

This package (and some of it's dependencies) require monolog/monolog in version ^1.22 while laravel 6 (and ignition) requires monolog/monolog ^1.12 || ^2.0

I managed to fix it for now and install tylercd100/lern in my laravel 6 by forcing a monolog version 1 in my composer.json :

"monolog/monolog": "^1.22"

Answer 2 · 2020-02-06T11:37:00.000Z

should I install "monolog/monolog": "^1.22" in my laravel-6.8 project before installing lern package?

Answer 3 · 2020-02-06T11:41:24.000Z

I edited my project's composer.json and added "monolog/monolog": "^1.22" in the require array.
Then I ran a composer update, before installing lern package.
Worked for me on laravel 6.14.0

@Eluia I don't want to downgrade monolog/monolog, I think tylercd100/lern package should support latest version of monolog/monolog ^2.0 so developers can easily install it on latest version of Laravel without any cumbersome.
THANKS

Same as you, I'd rather run monolog/monolog ^2.0.
Bu until devs fix the packages for laravel 6 and monolog 2 I'll have to run it with monolog 1

Answer 6 · 2020-02-06T17:28:23.000Z

Hey everyone, I was hoping that updating the version number in the composer.json would be sufficient to resolve the issue, but there are some needed code changes in some dependent packages that I also author that need to be fixed first before this can happen. Unfortunately, I am moving houses this week and I will have to put this off until next week. If anyone wants to fix the dependent packages they are: tylercd100/monolog-mailgun#2 tylercd100/monolog-sms#5
