Создание приложения Hello World с использованием AWS SAM: проблема при запуске "sam build"

/ 02 апреля 2020

Я только начинаю с AWS SAM. Я пытался следовать учебнику Amazon: https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/serverless-getting-started-hello-world.html. Но я застрял на Шаге 2: Когда я запускаю «sam build» в каталоге приложения, я получаю эту ошибку: 

C:\Users\emman\HelloWorldAPI>sam build
Building resource 'HelloWorldFunction'
Running PythonPipBuilder:ResolveDependencies

Build Failed
Error: PythonPipBuilder:ResolveDependencies - Could not satisfy the requirement: requests

Я использую Python 3.7.7 на anaconda. Как я могу исправить эту проблему зависимости?

Вот полная отладка:

Я нашел другой пост, говорящий, что я должен бежать: 

pip install wheel```

I did that in the anaconda prompt, but the module is already installed. 
I wonder if there is a conflict between two different pip applications...

Anaconda runs python 3.7.7 and the telemetry of "sam build --debug" returns :
```'pyversion': '3.7.6'```

Я решил свою проблему, удалив anaconda и загрузив вместо него стандартную версию Python.

Мне по-прежнему любопытно узнать, может ли Anaconda работать.

Я попытался посмотреть файл needs.txt. Единственной строкой были «запросы». Я попытался удалить его и снова запустить "sam build". Сборка прошла успешно, но я не совсем уверен, что это так просто ... Вот что возвращает «сборка sam»: 


Built Artifacts  : .aws-sam\build
Built Template   : .aws-sam\build\template.yaml

Commands you can use next
=========================
[*] Invoke Function: sam local invoke
[*] Deploy: sam deploy --guided
