【问题描述】：

我一直在尝试在我的 VS 代码中添加 Brownie，但我不断收到错误。我按照这些步骤操作，但没有任何效果。

python3 -m pip install --user pipx

python3 -m pipx ensurepath

pipx install eth-brownie

pipx 不起作用，所以我尝试了 - pip install eth-brownie

这是我在下面得到的错误...

【问题讨论】：

看看这个GitHub issue，它建议从 3.10 降级 Python

标签： python-3.x ethereum solidity web3 brownie

【解决方案1】：

在 vscode 中，ctrl+shift+p，输入 Python: select Interpreter 然后你会得到这个。

点击“输入解释器路径”

获取安装路径。在 macOS 和 linux 中应该是：

 ~/.local/pipx/venvs/eth-brownie/bin/python

现在在你将它添加到 vscode 之后，重新启动它。此设置适用于 VSCODE 终端。如果你运行：
```
   brownie --version
```

在 vscode 终端上你会得到版本。但是如果你想在与 vscode 不同的终端上运行brownie 命令，你必须在该终端的配置中添加路径
