Heroku and Kaleido

[MeganCowie]

I was trying to deploy an app to Heroku today and Kaleido kept getting in the way, with the error: ERROR: Could not find a version that satisfies the requirement kaleido==0.0.1 ERROR: No matching distribution found for kaleido==0.0.1

I was able to get around it by deleting Kaleido from my requirements.txt file so it's not a pressing issue for me, but I wanted to let you know in case it's relevant for others / future.

ps - I tried updating both pip and kaleido, and these ideas did not solve the issue.

Hi @MeganCowie, what was the entry you had in requirements.txt while receiving the error? Was there any version constraint on it?

[MeganCowie]

Hi Jon, Wow fast reply thanks :) Yes, the line is: "kaleido==0.1.0.post1", which is the result of creating a requirements.txt file via $ pip freeze > requirements.txt

Hi Jon,

I just recreated the issue, and here are some more details in case it's helpful:

1) requirements.txt file has the line kaleido==0.1.0.post1 2) After committing this update to git I try to deploy to Heroku via $ git push heroku main 3) This is the complete message:

4) I checked my installed version of Kaleido via $ pip show kaleido which returns:

Name: kaleido Version: 0.1.0.post1 Summary: Static image export for web-based visualization libraries with zero dependencies Home-page: UNKNOWN Author: Jon Mease Author-email: jon@plotly.com License: MIT Location: c:\users\m-cow\appdata\local\programs\python\python38-32\lib\site-packages Requires: Required-by:

5) I have tried uninstalling and reinstalling pip and kaleido according to your discussion in this issue https://github.com/plotly/Kaleido/issues/15 but the problem persisted.

Best, Megan

Thanks for your interest in Kaleido. We are currently working on an overhaul that might address your issue - we hope to have news in a few weeks and will post an update then. Thanks - @gvwilson
