Python Visual Studio 代碼的路徑問題

Question

我在嘗試本地調試 AWS Lamda (python 3.8) 時遇到問題。 從終端執行時，AWS SAM Cli 命令運行良好。 但是，在嘗試從 vscode 調試或構建時，它會引發錯誤。 似乎 vscode 正在為 python 3.8 版本選擇不同的路徑。

這是來自終端的配置路徑快照：

mbp$ which python
/usr/bin/python
mbp$ which python3
/usr/local/opt/python@3.8/bin/python3
mbp$ which aws
/usr/local/bin/aws
mbp$ which sam
/usr/local/bin/sam
mbp$ python --version
Python 2.7.16
mbp$ python3 --version
Python 3.8.8

這是 visual-studio-code 日志：

Answer 1

您可以嘗試的另一個解決方案是在您的項目目錄中創建一個.vscode文件夾，然后在該目錄中創建一個settings.json文件。 在文件里面創建

{
    "python.pythonPath": "<python path>",
}

將 python 路徑替換為 python 二進制文件的路徑。

在 vscode 視圖 > 命令面板 > Python: select 解釋器中設置 python 路徑 /usr/local/opt/python@3.8/bin/python3 后它工作了一次
