Hi @mfvitale
Did this work before? And which container are you referring to (The Angular or the Ionic one) ?

[dmastag]

You can try doing

apt-get install ruby-dev

I got this from https://stackoverflow.com/a/26161563/3227392

I am referring to Ionic container and doesn't work before.

This

apt-get install ruby-dev

not fix the problem?
