I tried installing brownie via pipx, pip and the github repo , but each time I get this error on running brownie:

vyper.exceptions.DecimalOverrideException: <exception str() failed>
Any help on fixing this would be appreciated.
I finally managed to solve this. I figured out that the error was due to vyper, as vyper --version also gave a similar error.
So, I went to the last exception raised:
File "/home/misterblack/.local/lib/python3.9/site-packages/vyper/old_codegen/parser_utils.py", line 38, in __setattr__
raise DecimalOverrideException("Overriding decimal precision disabled")
and opened the file mentioned ..../vyper/old_codegen/parser_utils.py, and commented the lines that were throwing the exception. Image of the commented code. This completely removed the error, as can be seen here. I don't know if it's the best approach, but it seems to be working. Success!
