    Composer: Cloning failed using an ssh key Link to this post

    I used the following command from my Mac/MAMP installation:

    composer create-project silverstripe/installer ./www 3.0.x-dev

    The resulting message was as follows:

    Installing silverstripe/installer (3.0.x-dev 8e074cdfee70c2bff60ae5e8818c344f2a4ce695)

    Cloning failed using an ssh key for authentication, enter your GitHub credentials to access private repos
    The credentials will be swapped for an OAuth token stored in /Users/martine/.composer/config.json, your password will not be stored
    To revoke access to this token you can visit https://github.com/settings/applications

    As I'm new to Composer, can anyone tell me what happened to make cloning the CMS fail, while framework seemed to go OK, and why entering my Github credentials is necessary to get the cms to clone?

    Thanks, Martine

    Just to elaborate: using the example version from the silverstripe docs everything goes smoothly:

    composer create-project silverstripe/installer ./wwwtest

    Just trying to get 3.0.x-dev fails on the cms only:

    composer create-project silverstripe/installer ./www 3.0.x-dev

    From my Mac I could get it by using git credentials (why?), from nix I get 'invalid credentials' and that's it

    OK, I got it!
    (Needed to create a ssl key for nix to get to the cms, but that's not really the issue)

    from this post:
    > If you install from a tag like, it'll use the github-generated
    > ZIPs by default, for both root and dependencies...

    So uses the Zip file, that is fast and can be downloaded without the need for a GitHub account.

    3.0.x-dev doesn't use the zipfile (why not) but it reverts to the Canonical url set up for the module in Packagist - much slower. But the issue is that the url is different for sapphire and cms

    framework: https://github.com/silverstripe/sapphire
    cms: git@github.com:silverstripe/silverstripe-cms.git

    While the https:// url can be cloned without the need for a ssh key, the git@... does want the ssh key. What would be the advised canonical?
