我在想这个问题与版本的版本有关，但是在使用了所有导入包的最后一个版本后，我遇到了同样的问题。

有人可以帮我弄这个吗？

当我的 brownie-config.yaml 中有错字时，我多次遇到此错误......希望这会有所帮助。

所以我遇到了同样的问题，修复很简单，我忽略了，我想我会在这里发布给其他可能需要同样简单修复的人：

起初：

dependencies:
   -smartcontractkit/chainlink......

固定的：

depedencies:
   - smartcontractkit/chainlink......

我只需要在连字符后添加一个空格

我遇到了同样的问题并且无法找到根本原因，但是在新目录中重新制作项目以某种方式解决了我的问题。

以前我曾尝试删除所有依赖项以测试 brownie compile 是否仅适用于基本合同，但奇怪的是遇到了这些错误：

Brownie v1.17.1 - Python development framework for Ethereum

  File "brownie/_cli/__main__.py", line 64, in main
    importlib.import_module(f"brownie._cli.{cmd}").main()
  File "brownie/_cli/compile.py", line 32, in main
    project_path = project.check_for_project(".")
  File "brownie/project/main.py", line 548, in check_for_project
    structure_config = _load_project_structure_config(folder)
  File "brownie/_config.py", line 272, in _load_project_structure_config
    data = _load_config(project_path).get("project_structure", {})
AttributeError: 'NoneType' object has no attribute 'get'

希望这会有所帮助，似乎这可能是源于布朗尼的问题。

我的 brownie-config.yaml 中的一个错误导致了我的问题，我输入了

- smartcontractkit/chainlink-brownie-contract@0.2.1

而不是拥有

- smartcontractkit/chainlink-brownie-contracts@0.2.1

为了澄清我在需要“合同”时输入了“合同”，希望这对某人有所帮助。
