Python build is not working anymore

#1

Everything was working file until last week. It started breaking so I upgrade to python 3.8 but even that is failing. I also upgraded to focal image.

its failing with error /opt/build-bin/run-build-functions.sh: line 205: /opt/buildhome/pythonpython-3.8/bin/activate: No such file or directory

here’s pipfile

[[source]]
name = "pypi"
url = "https://pypi.org/simple"
verify_ssl = true

[packages]
mkdocs = "==1.2.3"
mkdocs-material = "==7.3.6"
pymdown-extensions = "==9.0"
Pygments = "==2.10.0"
Markdown = "==3.3.4"

[requires]
python_version = "3.8"

The better the post - the faster the answer.

Hey @bilal-fazlani,

I took a look at your recent builds and most of them seem successful and the ones that failed around the time you posted, had a different error in almost each one.

Are you still seeing this issue? if yes, do you mind linking us to the deploy that has this specific issue you mention?

#3

here is an example failed build.

https://app.netlify.com/sites/commanddotnet/deploys/6192c9bd59d5580008860ead

The recent build is passing because I am now using requirements.txt as a workaround. It is not working with pipfile. I would like to go back to using pipfile whenever that starts working again.

#4

Your Pipfile uses Python 3.7: commanddotnet/Pipfile at e968016036f586a74f156dca1d52c73982cbbabf · bilal-fazlani/commanddotnet · GitHub

Netlify doesn’t use that as mentioned here: Netlify App

You can check the list here: build-image/included_software.md at focal · netlify/build-image · GitHub

You need to use Python 3.8

#5

I have created a small test repo to reproduce this : Netlify App

Here, I am using python 3.8 with pipfile. It doesn’t work.
If I convert this into requirements.txt then it works

#6

netlify.toml

[build]
  publish = "site/"

  command = "mkdocs build"

Pipfile

[[source]] 
url = "https://pypi.python.org/simple"
verify_ssl = true
name = "pypi"

[packages] 
mkdocs-material = "==8.0.2"

[requires] 
python_version = "3.8"
#8

Hey @bilal-fazlani,

I could confirm this behaviour and have filed it for the team to look at:

#9

Is this related? When using mkdocs build (and without any environment variables set), Netlify is trying to load Python 3.7:

9:41:06 AM: Installing dependencies
9:41:06 AM: /opt/build-bin/run-build-functions.sh: line 351: /opt/buildhome/python3.7/bin/activate: No such file or directory
9:41:06 AM: Error setting python version from runtime.txt
#10

Can’t say for sure @jo81mj0y, could you share your site name?

#11

Thanks. It’s https://super-starship-a6ef73.netlify.app.

#12

Netlify currently only supports Python 2.7 and 3.8. Maybe try using Python 3.8 instead?
