Newbie trouble

[mjmare]

Hi
I'm trying out MyPaas, but ran into some issues:

Docs do not detail installation on the work machine. It also does not specify the toml requirement.
It seems to be sufficient to have this in my requirements.txt:

mypaas
toml

I followed the getting started instructions and the tried to run the hello-world example. However, when pushing

mypaas push xxxx.yyyy.nl .

(xxxx.yyyy.nl is not the real server name of course)

I got this error:

Testing on MacOS with a DigitalOcean docker droplet.

It also does not specify the toml requirement.

I just fixed this. Thanks for the heads-up!

As for that certificate error. I read that "Normally the python installation has access to root certificate authorities. However on some OSes such as OSX, the root CA are empty."

Maybe this helps: https://stackoverflow.com/questions/52805115/certificate-verify-failed-unable-to-get-local-issuer-certificate/56031239#56031239

If there is a solution in the form of something that we can adopt in MyPaas, that would be great!

Thanks. With my limiting understanding of the matter I ran this program: https://github.com/python/cpython/blob/master/Mac/BuildScript/resources/install_certificates.command
in my venv (since I do not use the system python, but rather the Homebrew version).
However I'm still getting the same error.
