I set up a private network on my computer and was running some codes written in Python using
web3.py, until I faced ImportError:
ImportError: The 'pyparsing' package is required; normally this is bundled with this package so if you get this warning, consult the packager of your distribution.
This didn't happen in the beginning. I was running my codes and everything was running good, but today while playing around with
eth_tester I faced this error, which looks more like common Python error. And from the time I first saw this error message I was unnable to run any of my codes, which were running normally before.
The error is invoked by this line:
I have these versions of modules in my PyCharm:
Pyparsing 2.2.0 Web3 3.11.1 pip 9.0.1
- I am using WIN7SP1
- Codes are being launched from the Command-line interface
- I tried to reinstall
eth_testerin case problem was in module, but it didn't help
When I try
import pyparsing it says:
AttributeError: module 'copy' has no attribute 'copy'
Yes, I was thinking to ask this question on StackOverflow, because I still think that this is more of Python problem, but this error happens only when I use web3.py and not any other module. So the problem might be in web3.
I appreciate any suggestions and comments on how to solve this problem.
