找不到部署无服务器的python处理程序

Question

我正在尝试在gitlab上使用无服务器部署AWS Lambda函数。由于我需要一些外部和本地模块，因此我使用了插件serverless-python-requirements。我的gitlab-ci.yml就是这样

image: nikolaik/python-nodejs:python3.7-nodejs11

cache:
  paths:
    - node_modules/

stages:
  - deploy

before_script:
  - npm config set prefix /usr/local
  - npm install -g serverless
  - npm install

deploy:
  stage: deploy
  script:
    - serverless deploy --stage dev --verbose

我的serverless.yml：

service: my-function

plugins:
  - serverless-python-requirements

package:
  exclude:
    - ./node_modules/**
    - node_modules/**
    - .gitignore
    - .gitlab-ci.yml
    - package-lock.json
    - package.json

custom:
  pythonRequirements:
    dockerizePip: false

provider:
  name: aws
  runtime: python3.7
  stage: dev
  region: us-east-1

functions:
  hello:
    handler: handler.handle
    events:
      - http:
          path: hello
          method: post

和我简单的handler.py

def hello(event, context):
    return {"statusCode": 200}

现在，当我执行该函数时，出现此错误：

Runtime.ImportModuleError: Unable to import module 'handler': attempted relative import with no known parent package

这就像默认模板，但我无法运行
