Composer Content-Length Mismatch

Question

Answer 1

Just change the composer default repo url:

composer config -g repo.packagist composer https://packagist.org
composer config -g github-protocols https ssh

It changes or sets the packagist repo to be used by https only.

This fixes any issues with local composer.json files too. No need to mess around with the composer.json file localy or global.
