As a longtime beancount user- it should be easy to install- there are packages for most OSes, they mostly work, the maintainer, Martin Blais is amazing and indefatigable, and the community is active and friendly and technical.
But the "how to get going" part is where I find the real difficulty lies.
There is a conceptual friction in double-entry accounting, which beancount enforces. If you do not have prior exposure to it, even if you are financially and mathematically inclined- grokking double entry can be a life-changing practice. It is the Iyengar Yoga to the 7 minute workout that is just tracking transactions as per GnuCash or Quicken or whatever.
One has to have the appetite to consume a worldview. As someone living in that world, FWIW, I highly recommend it. I would not undersell the conceptual work required. It is not for everyone.
But if the approach speaks to you, reach out on the mailing list and people will help with the mechanics.
A thousand times yes! the abstraction of double-entry accounting is absolutely central to understanding the modern economy and why (large) economic agents behave the way they do. It’s also essential for understanding fiat money, which is more or less just numbers in a double-entry ledger.
The documentation says to type "pip install beancount". That doesn't seem hard, so I'm guessing you're having some other problem? If you post on the mailing list, people will help you.
