Hi there ! I tried to install a clean copy of Opigno 2.0 using composer as per the manual (https://opigno.atlassian.net/wiki/spaces/OUM20/pages/361922562/Installation+with+Composer). I used the following command : composer create-project opigno/opigno-composer opigno_2_composer I am getting the following error: - Installing mozilla/pdf.js (dev-master origin/gh-pages): Cloning origin/gh-pages from cache origin/gh-pages is gone (history was rewritten?) [RuntimeException] Failed to execute git checkout 'origin/gh-pages' -- && git reset --hard 'origin/gh-pages' -- fatal: invalid reference: origin/gh-pages I tried to continue the install using composer update but got the same error. Any ideas on how to get the installation completed ?

Looks as though a composer upgrade was needed. composer upgrade Gathering patches for root package. > DrupalProject\composer\ScriptHandler::checkComposerVersion Loading composer repositories with package information Updating dependencies (including require-dev) Package operations: 103 installs, 3 updates, 0 removals Gathering patches for root package. Gathering patches for dependencies. This might take a minute. - Installing mozilla/pdf.js (dev-master origin/gh-pages): Cloning origin/gh-pages from cache - Installing drupal/platon (1.2.0): Loading from cache - Installing drupal/group (1.0.0-rc2): Loading from cache .... snip ....

I am suffering the same problem. My composer version is version 1.8.5. I am trying with MAMP and with Acquia Desktop always with the same result as you. Do you already know what can be the reason? I have a friend that has tried with LAMP and he has got it at the first try.

Hi, I run the command "composer create-project opigno/opigno-composer" and it installs couple of minutes all kind of modules. But after the install, my plain Drupal 8 site still looks empty, nothing added anywhere. Then I found that there is a new directory in my htdocs folder "opigno-composer" What are the next steps to install Opigno? I have tried to install it now many times on AWS Bitnami LAMP stack Drupal 8.7.4 Debian. Where I could get step by step instructions how to install Opigno? When I access that folder, permission denied. What is that folder what composer does, it is another drupal installation or what?
