pythonodbcbrownieerc721

Use external packages in eth-brownie?


I am trying open a ERC721 smart contract in Brownie on VSCode and loop through the token ids and set the URI of each in each iteration. I execute the script with brownie run scripts/parcel_asset/testpyodbc.py. I am trying to use an ODBC driver named pyodbc to query an Access database and create a cursor to iterate. It works fine when running as just a python script but Brownie gives a error ModuleNotFoundError: No module named 'pyodbc'. Is there a way to his odbc with Brownie?

Below is the error I get

\nft> brownie run scripts/parcel_asset/testpyodbc.py
Brownie v1.17.2 - Python development framework for Ethereum
File ".\scripts\parcel_asset\testpyodbc.py", line 1, in <module>
import pyodbc

Solution

  • I found this on a Discord channel: brownie is installed to its own virtual environment, if you want other packages to work you have to "inject" them into the brownie virtualenv: When using brownie I can't use external modules, pip install doesn't work brownie but full disclosure, i tried this for another package i was working with to no avail.

    pipx inject eth-brownie pyodbc 
    

    This fixed the problem
