【问题描述】：

我正在尝试使用 localstack 在本地部署我的 lambda，但它失败了，因为它无法解析变量 configFile。

我的框架版本是3

service: score-api

frameworkVersion: '3'

plugins:
  - serverless-deployment-bucket
  - serverless-localstack

custom:
  stage: ${opt:stage, self:provider.stage}
  region: ${opt:region, self:provider.region}
  configFile: ${file(./config/${self:custom.stage}.json)}
  serviceName: test-api
  priority: 180
  optionsOnly: false
  redirect: false
  localstack:
    # list of stages for which the plugin should be enabled
    stages:
      - dev
    host: http://localhost
    autostart: true  # optional - Start LocalStack in Docker on Serverless deploy
    #endpoints:
      # This section is optional - can be used for customizing the target endpoints
      #S3: http://localhost:4572
      #DynamoDB: http://localhost:4570
      #CloudFormation: http://localhost:4581
      #Elasticsearch: http://localhost:4571
      #ES: http://localhost:4578
      #SNS: http://localhost:4575
      #SQS: http://localhost:4576
      #Lambda: http://localhost:4574
      #Kinesis: http://localhost:4568
    debug: true
    lambda:
      mountCode: True # enable this flag for performance (True didn't work for me)
    docker:
      sudo: False # enable this flag to run "docker ..." commands as sudo
  stages:
    dev:

【解决方案1】：

这似乎是无服务器框架版本 3.x 的问题。我将无服务器框架版本降级为 2.x，错误自行解决。

''' npm install -g serverless@2 '''
