Unable to deploy to production

trellis
1

I am encountering possibly a bug in Ansible. I’m using a previous version of trellis and following this guide on how to deploy:

When I ran deploy step (server was already provisioned before and I deploy using the command: ./deploy.sh production <my_domain>), it has this weird issue:

ERROR! Unexpected Exception: must be string, not None

Here is the full log using -vvv:

I don’t really know what to do to debug this, I deployed the website using the same command 2 days ago and it was fine.

I would greatly appreciate if somebody could help me.

Have you changed Ansible versions before trying to do this deploy?

@Jon I’m happy to see you here :smiley: I didn’t touched Ansible :confused: I don’t know if it’s relevant or not but I did create a new user account on my machine and then install Python with Anaconda packages because I need that stuff for my school data mining projects. I’ll try downgrading to Ansible 2.2.0 right now (it’s 2.3.0 in my machine now)

@Jon After downgrading to Ansible 2.2.0 it still has the same issue :confused: I swear that 2 days before it was all fine, I deployed multiple times to the remote server. Do you have any idea on how I can further debug this?

@Jon Somehow there was a problem with python’s package folder. I ran:
brew link --overwrite python then everything works fine
