Visual Studio 代码的 Python 路径问题

Question

我在尝试本地调试 AWS Lamda (python 3.8) 时遇到问题。从终端执行时，AWS SAM Cli 命令运行良好。但是，在尝试从 vscode 调试或构建时，它会引发错误。似乎 vscode 正在为 python 3.8 版本选择不同的路径。

这是来自终端的配置路径快照：

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

这是视觉工作室代码日志：

Answer 1

您可以尝试的另一个解决方案是在您的项目目录中创建一个.vscode 文件夹，然后在该目录中创建一个settings.json 文件。在文件里面创建

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

将 python 路径替换为你的 python 二进制文件的路径。

Answer 2

在 vscode 视图 > 命令面板 > Python: 选择解释器中设置 python 路径 /usr/local/opt/python@3.8/bin/python3 后它工作了一次
