The library is not packaged for pip installations. (This has been in the Readme's "To Do" for a while.) It would be relatively easy to implement. I can do it later today. (Would be great if you or someone else could do it however.)
I'm sorry not been able to figure out I couldn't do the installation using pip, I am a beginner in programming and unfortunately have no idea how to package pips. If you or someone else could do it, would be great! Thanks

Look at the installation section in README.md.
Many thanks for updating the peregrine installation to use pip.
I did:
pip install peregrinearb"
and run, as the provided example:
from peregrinearb import get_opportunity_for_market import asyncio opportunity = asyncio.get_event_loop().run_until_complete(get_opportunity_for_market("BTC/USD")) print(opportunity)
got this answer:

I installed the utils module, using:
pip install utils
And run the same code above, but got:

Am i doing something wrong? Thank again.
Hi, Thanks! This was actually a very important (and thankfully simple) bug. For some reason, the relative imports got all screwed up. It is fixed now. Please try reinstalling/ upgrading and let me know if you have more problems.

Hi Ward,
Thanks for fixing this!
I tried to run the examples you provide and the 1st code below, worked smoothly, but from 2nd to the last, I got some errors:
This one worked!!

Hi, Thanks! This was actually a very important (and thankfully simple) bug. For some reason, the relative imports got all screwed up. It is fixed now. Please try reinstalling/ upgrading and let me know if you have more problems.

Many thanks for updating the peregrine installation to use pip.
I did:
pip install peregrinearb"
and run, as the provided example:
from peregrinearb import get_opportunity_for_market import asyncio opportunity = asyncio.get_event_loop().run_untilcomplete(get opportunity_for_market("BTC/USD")) print(opportunity)
got this answer:

I installed the utils module, using:
pip install utils
And run the same code above, but got:

Am i doing something wrong? Thank again.
