AttributeError in Lesson 6 - 5:36:33 timestamp

[ArcusConsulting]

Not sure why I'm getting an AttributeError:

[cromewar]

1. Make sure you have the MockV3Aggregator.sol on contracts/tests-
2. Delete your build folder and compile again brownie compile.

Hopes this help.

[cromewar]

I see, please as @PatrickAlphaC suggested could you share your MockV3Aggregator code here please? or copy-past it from here: https://github.com/PatrickAlphaC/brownie_fund_me/blob/main/contracts/test/MockV3Aggregator.sol

[ArcusConsulting]

Copy-pasted from GitHub... See below

[cromewar]

It seems everything is ok, for me is a problem with your brownie installation, using the recommendations on this thread: #295

• use virtual env,
• install brownie to the venv,
• reinstall your ganache-cli to the directory you own (or simply chown your node_modules dir)

[ArcusConsulting]

... I don't know how to use virtual env and i don't know what you mean in your 3rd bullet point. I'll see what i can manage later tonight after work.

[cromewar]

Here you have a guide about python virtual envs.
The third bullet point means to not install ganache using super user privileges (like using admin on windows o Sudo on linux).

I had the same error! Remember to put the parentheses after get_account in the MockV3Aggregator.deploy

    MockV3Aggregator.deploy(
        DECIMALS, Web3.toWei(STARTING_PRICE, "ether"), {"from": get_account()}

[cromewar]

@ArcusConsulting does this work for you?

[ArcusConsulting]

Will let you know tonight!

[ArcusConsulting]

It worked! Thank you, everyone!

[PatrickAlphaC]

Wooooo!!!

[DarrenWayn]

the get_account => () don't forget to use this as a function
