ValueError: Dotenv specified in config but not found at path

Question

Hello there I'm currently following this tutorial by Patrick Collins however I'm stuck at deploy script.

PS C:\Users\aixax\Desktop\nft-from-scratch> brownie run scripts/advanced_collectible/deploy_advanced.py
INFO: Could not find files for the given pattern(s).
Brownie v1.17.1 - Python development framework for Ethereum

  File "C:\Users\aixax\AppData\Local\Programs\Python\Python310\lib\site-packages\eth_brownie-1.17.1-py3.10.egg\brownie\_cli\__main__.py", line 64, in main
    importlib.import_module(f"brownie._cli.{cmd}").main()

    raise ValueError(f"Dotenv specified in config but not found at path: {env_path}")  
ValueError: Dotenv specified in config but not found at path: C:\Users\aixax\Desktop\nft-from-scratch\.env

I'll inlclude my python , brownie config and .env file for the reference. The private key is my own private key with 0x at the front.

deploy_advanced.py :

from brownie import AdvancedCollectible, accounts, network, config

def main():
   dev = accounts.add(config['wallets']['from_key'])
   print(dev)

brownie-config.yaml:

dependencies: 
- OpenZeppelin/openzeppelin-contracts@3.4.0
- smartcontractkit/chainlink-brownie-contracts@1.0.2
compiler:
  solc:
    remappings:
     - '@openzeppelin=OpenZeppelin/openzeppelin-contracts@3.4.0'
     - '@chainlink=smartcontractkit/chainlink-brownie-contracts@1.0.2'
dotenv: .env
wallets:
  from_key: ${PRIVATE_KEY}
  from_mnemonic: ${MNEMONIC}

file.env:

export PRIVATE_KEY={0x___________________________________________________________}

Answer 1

Your .env file is located at the wrong place.

It's expecting it to be at \Users\aixax\Desktop\nft-from-scratch\.env

You'll either need to move the file there, or update in your brownie-config.yaml where it's located at the dotenv key.

Answer 2

.env file should be at root of your project. i.e. Here your root directory is \Users\aixax\Desktop\nft-from-scratch\.

So your .env file should be at C:\Users\aixax\Desktop\nft-from-scratch\.env
