Lesson 5: cannot import name 'SimpleStorage' from 'brownie'

[s1n7]

Hey Guys! :)
I'm having issues deploying the deploy.py file. The issue arrised when I tried to import SimpleStorage to the deploy.py script. There is an error occurring saying: "cannot import name 'SimpleStorage' from 'brownie' ". However, the testing approach works fine, importing SimpleStorage there seems to be no problem at all.

Could you add:

1. What command you're running
2. The full error
3. The script code
4. THe contract code
5. An image of what your text editor looks like

1. command I'm running: brownie run project/scripts/deploy.py The command looks like this because I had to create a virtual environment and had to create an empty folder (project) because somehow pipx does not install brownie.

2. full error:
   

3. script code from deploy.py:
   `from brownie import SimpleStorage, accounts, network, config
   import os

from brownie.network import account

def deploy_simple_storage():
#work with local accounts:
account = accounts[0]
simple_storage = SimpleStorage.deploy({'from': account})
stored_value = simple_storage.retrieve()
print(stored_value)

def get_account():
if(network.show_active() == "development"):
return accounts[0]
else:
return accounts.add(config["wallets"]["from_key"])

def main():
deploy_simple_storage()`

4. SimpleStorage.sol code:
   `// SPDX-License-Identifier: MIT

pragma solidity ^0.6.0;

contract SimpleStorage {
// public defines the visibility, default is "internal" as visibility
uint256 public favoriteNumber;

bool favoriteBool;

// ways to define new types in solidity
struct People {
    uint256 favoriteNumber;
    string name;
}

//dynamic array: can change size
People[] public people;
mapping(string => uint256) public nameToFavoriteNumber;

function store(uint256 _favoriteNumber) public {
    favoriteNumber = _favoriteNumber;
}

// view, pure
function retrieve() public view returns (uint256) {
    return favoriteNumber;
}

//memory: data will only be stored during the execution of the function
//storage: data will persist after the function executes
function addPerson(string memory _name, uint256 _favoriteNumber) public {
    people.push(People(_favoriteNumber, _name));
    nameToFavoriteNumber[_name] = _favoriteNumber;
}

}
`

I faced a similar problem before, try to do this instead:

Create a Folder (for the project), inside of if place another to (One for the virtualenv and another for the code itself) Something like this:

Project folder
| - dev (for code)
| - virtualenv

then, delete the build folder and compile again:

brownie compile

Finally try again running the script, hope this helps.

Note: remember to install eth-brownie instead of just brownie.
Note: to, don't forget to activate the environment, as it is now outside the code folder activate it using ../restOfThePath.

It worked now, thank you! :)

No problem, I'm glad it helped :)
