我正在按照本教程构建 SAM 应用程序：https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/serverless-getting-started-hello-world.html
当我执行 sam build 时，出现以下错误
❯ sam build
Building codeuri: hello_world/ runtime: python3.8 metadata: {} functions: ['HelloWorldFunction']
Build Failed
Error: PythonPipBuilder:Validation - Binary validation failed for python, searched for python in following locations : ['/usr/bin/python'] which did not satisfy constraints for runtime: python3.8. Do you have python for runtime: python3.8 on your PATH?
我通过这样做检查了我的蟒蛇
❯ which python
python: aliased to python3
当我做python版本时，我得到了这个
❯ python --version
Python 3.8.2
那么我缺少什么以及如何解决这个问题？
