I was trying to implement this script to be able to wrap ETH into wETH.

So, I installed Brownie by running pip3 install eth-brownie.

However, I am having trouble importing interface in the first line of the script: from brownie import accounts, config, network, interface.

When it's run, I get the following error message:

from brownie import accounts, config, network, interface
ImportError: cannot import name 'interface' from 'brownie' (/home/blackwidow/.local/lib/python3.8/site-packages/brownie/__init__.py)

It appears I am not the only person with this issue as this has been reported in the past with no apparent solution.

    @PatrickCollins Am I supposed to find interface folder in .brownie folder? If so, no, I only have accounts ethpm and packages. I do have interfaces folder along with build contracts reports scripts and tests folders when i run brownie init Also, I have tried both pipx install eth-brownie and pip install eth-brownie. One thing i noticed is, if I use pip, it does compile the python script with from brownie import accounts but it does not if I had used pipx. They both regardless recognize brownie if I enter brownie in the terminal. Thank you.
