找不到无服务器的Python本地模块

如何解决找不到无服务器的Python本地模块

我希望将本地python模块文件导入到我的无服务器项目中的处理程序文件中，但是尽管此本地文件与处理程序文件一起位于父目录中，但似乎无法识别该模块。我对python无服务器设置相对较新，并且想知道无服务器文件导入的工作方式是否缺失。

以下是文件：

/ (parent directory)
data.py
gather_keys_oauth2.py

错误消息：

Proxy Handler could not detect JSON:   File "/Users/user/.nvm/versions/node/v12.14.0/lib/node_modules/serverless/lib/plugins/aws/invokeLocal/invoke.py",line 72,in <module>

    import gather_keys_oauth2 as Oauth2
ModuleNotFoundError: No module named 'gather_keys_oauth2'

data.py：

import json
from datetime import timedelta,datetime
import math
import gather_keys_oauth2 as Oauth2
import fitbit

def auth(event,context):

    CLIENT_ID = '*client*'
    CLIENT_SECRET = '*secret*'

    server = Oauth2.OAuth2Server(CLIENT_ID,CLIENT_SECRET)
    server.browser_authorize()

    ACCESS_TOKEN = str(server.fitbit.client.session.token['access_token'])
    REFRESH_TOKEN = str(server.fitbit.client.session.token['refresh_token'])

    auth2_client = fitbit.Fitbit(CLIENT_ID,CLIENT_SECRET,oauth2=True,access_token=ACCESS_TOKEN,refresh_token=REFRESH_TOKEN)

    print(auth2_client)

    body = {
        "message": "Auth","input": event
    }

    response = {
        "statusCode": 200,"body": body['message']
    }

    return response

解决方法

您的lambda没有包装您要导入的模块。您可以为此使用serverless-python-requirements插件。

它可以本地安装或通过以下方式安装在管道上

sls plugin install -n serverless-python-requirements 

您可以将其添加到serverless.yml文件中，然后尝试部署

# this part might not be needed depending on size of utils
custom:
  pythonRequirements:
    zip: true

# This plugin allows us import dependencies
plugins:
  - serverless-python-requirements
