Python找不到Brownie文件

Question

我正在学习一篇关于Solidity和Python的教程(参考https://www.youtube.com/watch?v=M576WGiDBdQ&t=5447s)。

我已经到了安装Python和Brownie并通过VSCode运行的阶段，但在询问Brownie的版本brownie --version INFO: Could not find files for the given pattern(s). Brownie v1.17.1 - Python development framework for Ethereum时，我收到了以下通知

当我尝试对一个名为deploy.py (def main(): print ("hello!") )的文件运行一个非常基本的脚本时，结果如下：

PS C:\Users\chret\Documents\demo\brownie_simple_storage> brownie run scripts/deploy.py
INFO: Could not find files for the given pattern(s).
Brownie v1.17.1 - Python development framework for Ethereum

BrownieSimpleStorageProject is the active project.

我试着从Python卸载并重新安装到Brownie，更改Brownie的文件存放位置，但由于我的知识非常有限(完全初学者)，我现在被卡住了。

更新我再次重新安装了Python、pipx和brownie，现在消息略有不同，但仍然不能运行deploy.py的脚本。脚本是：

def main():
    print("Hello!")

当前的错误消息是：

PS C:\Users\chret\Documents\demo\brownie_simple_storage> brownie run scripts.deploy.py

INFO: Could not find files for the given pattern(s).
Brownie v1.17.1 - Python development framework for Ethereum

任何帮助都将不胜感激:)

Answer 1

您的deploy脚本位于contracts文件夹/目录中。

它需要位于项目的脚本目录中，即brownie_simple_storage/scripts文件夹中。

尝试将其移动到那里，并在该文件夹中运行您的脚本。

编辑：

您可能需要安装nodejs和ganache-cli
