Crashes with undefined index: 0 inside docker container

[k0pernikus]

I have included prestissimo inside a project. We are using docker container and prestiismio is globally installed during the build.

It worked well on most cases, yet one developer's machine has the issue:

[ErrorException]    
  Undefined index: 0

What could be the issue here?

[k0pernikus]

It seems the issue was related to too many requests to the github.com api which was throwing 403 errors. Hence, there were no files and nothing could be properly installed.

Adding an auth.json for composer to use at the projects parent folder with a personal access token to public github repositories fixed the issue:

{
    "github-oauth": {
        "github.com": "YOUR_GITHUB_ACCESS_TOKEN"
    }
}

I think this is the same problem #41

Please try 0.1.10.

$ composer global update hirak/prestissimo --no-plugins

[k0pernikus]

@hirak I am not sure it's entirely a duplicate as the issue went away, as pointed out, after adding an auth.json. No update of prestissimo was required.

@hirak I found useful the tweak about github-auth. Could you add/mention the tweak in README?
