`Aborting graph creation: Problem getting dependency data` issue

[chenrui333]

Trying to regression testing pyflow, but ran into some Aborting graph creation: Problem getting dependency data failure.

How to reproduce

• brew install pyflow
• virtualenv setup with python 3.9.14
• pyflow init
• pyflow install boto3

Error log as below

             It's taking a long time to get dependency data - this usually suggests that the dependency tree is being newly built. Please try again in a few minutes, and if the error still occurs, consider opening an issue on github.

I get a similar error on different install process macos(x86):

• install asdf (via git/zsh)
• install python 3.10.8 (via asdf) and set local default
• install pyflow via cargo install pyflow
• mkdir libraries && cd libraries

I saw a request to pydeps.herokuapp.com, could it be this app just died due to Heroku plan limits, hence we can't get any dep data from it???

that is highly possible, heroku killed lots of apps recently.

The pydeps.herokuapp.com url is being used here and it's not working anymore.

I made a clone of the server, but to use it you need to replace the URL in that line in the code base, and build your own pyflow binary with cargo build --release. I made a PR to allow setting the URL via envvars.
