No module named flask

I've just installed puppet board by following the instructions at https://forge.puppet.com/puppet/puppetboard, but I can't start it. Apache error log repeats:

Honestly I don't know anything about python, so can you suggest what to do? Workaround?

Thanks!

Well, I've had to learn few things obviously. So your module missing the following in order to actually work:

  # PuppetBoard
  class { 'puppetboard':
    manage_git        => false,
    manage_virtualenv => true,
    reports_count     => 40, 
  }->
  python::pip { 'Flask':
    virtualenv => '/srv/puppetboard/virtenv-puppetboard',
    proxy      => 'http://internal-proxy.mydomain.com:8080',
  }->
  python::pip { 'Flask-WTF':
    virtualenv => '/srv/puppetboard/virtenv-puppetboard',
    proxy      => 'http://internal-proxy.mydomain.com:8080',
  }->
  python::pip { 'WTForms':
    virtualenv => '/srv/puppetboard/virtenv-puppetboard',
    proxy      => 'http://internal-proxy.mydomain.com:8080',
  }->
  python::pip { 'pypuppetdb':
    virtualenv => '/srv/puppetboard/virtenv-puppetboard',
    proxy      => 'http://internal-proxy.mydomain.com:8080',
  }

After adding this everything went well, and everything works.

Sorry for not creating pull request, but at the moment I don't have time to go through your code. You'll change it yourself easily.

Thanks!

is there any way you can provide this as patch to our module, @peske?

Actually, these modules are present in the repository:
https://github.com/voxpupuli/puppetboard/blob/master/requirements.txt

it looks like new setuptools module is broken, so python module just fails:

In english:

On 22/02/2017, I had the same problem as @peske quoted in the beginning of the issue ...
I was installing PuppetBoard on Red Hat 7.3 64 bit. And I solved by adding in the site.pp file the lines of the section "Configure Puppetboard" of the statement below.

Thanks to @peske for reporting the tip and thanks to all developers of community @voxpupuli that work in this module and PuppetBoard. Helped me a lot at work.

Hug.
Stay with God. O/

Eu estava instalando o PuppetBoard no Red Hat 7.3 64 bits. E resolvi adicionando no arquivo site.pp as linhas da seção "Configure Puppetboard" da declaração abaixo.

Obrigado a @peske por reportar a dica e obrigado a todos os desenvolvedores da comunidade @voxpupuli que trabalham neste módulo e do PuppetBoard. Me ajudou bastante no trabalho.

Abraço.
