问题布朗尼设置，不确定Ganache是​​否正确安装了-Chainlink Hackathon

Question

我是这个空间的新手，并且有一个问题让布朗尼运行我的第一个部署脚本。我正在通过Chainlink Hackathon学习，并遵循Patrick Collins的Brownie教程。我认为问题是Ganache。任何帮助将不胜感激。

当我要求Ganache的版本时 - 说找不到（见下文）。当我尝试通过NPM安装时，我收到错误13。这与Mac OS有关吗？

尝试部署脚本时的错误消息：

布朗尼运行脚本/deploy.py

这是由chainlink hackathon提供的部署脚本。视觉工作室代码中突出显示布朗尼的错误消息（“导入“布朗尼”无法解决的塔...”）

from brownie import SimpleStorage, accounts

def main():
    account = accounts[0]
    simple_storage_contract = SimpleStorage.deploy({"from": account})
    print(simple_storage_contract.number())

Answer 1

该错误实际上与Ganache无关（Ganache被卡在那里发生的事实；这意味着它在该IP地址和端口上运行）。

发生的事情是，您在第8行中的decloy.py文件中有一个语法错误。它说您有simple.storage当您想要的是simple> simple> simple_storage（使用下划线而不是该期间）。确保修复脚本中的第8行并保存文件。

Answer 2

写终端

sudo strong textnpm install -g ganache-cli
