连接到 Brownie/Rinkeby 时出现问题

Question

我对这个编程还很陌生，可能需要更多练习，但我在尝试连接到 Rinkeby 测试网时遇到了问题，似乎看不出问题所在（Windows 10，Powershell ) 不确定它是否是 .env 或我如何设置它们，但我会发送代码或使用屏幕截图创建的相应文件，以查看是否有人可以阐明问题。复制粘贴代码和环境变量的一些屏幕截图。非常感激您的帮忙。出于某种原因，.env 中的导出命令似乎没有执行（第三个附件）。

谢谢

错误：

    Brownie v1.18.1 - Python development framework for Ethereum

BrownieSimpleStorageProject is the active project.

KeyError: 'wallets'

deploy.py:

    from brownie import accounts, config, SimpleStorage, network


def deploy_simple_storage():
    account = get_account()
    simple_storage = SimpleStorage.deploy({"from": account})
    # Transaction
    # Call
    stored_value = simple_storage.retrieve()
    print(stored_value)
    transaction = simple_storage.store(15, {"from": account})
    transaction.wait(1)
    updated_value = simple_storage.retrieve()
    print(updated_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()

这是 .env 文件：

export WEB3_INFURA_PROJECT_ID=xxx
export PRIVATE_KEY=xxxx

布朗尼-config.yaml 文件：

dotenv: .env
wallets:
    from_key: ${PRIVATE_KEY}

Enviroment variable

Environment variable

.env file export

Answer 1

config 从根目录中的 brownie-config.yaml 文件读取。确保文件的位置在根目录中，并且它的名称在项目中是正确的。
