将serverless框架与serverless-offline和jest单元测试模块一起使用时，我遇到了持续性错误。
我正在尝试使用serverless-jest-plugin来测试我的无服务器功能（lambda），jest应该在serverless上集成jest。以下是我serverless.yml中的custom:
default:
stage: dev
table:
dictionary: Dictionary
rules: Rules
jest:
verbose: true
testResultsProcessor: jest-junit
modulePaths: ["<rootDir>/node_modules", "<rootDir>/lib"]
roots: ["<rootDir>/tests"]
testEnvironment: node
plugins:
- serverless-jest-plugin
- serverless-dynamodb-local
- serverless-offline
配置：
sls invoke test我有一个lambda函数，它使用dynamoDB获取一些数据等。
每当我使用$ sls invoke test
FAIL tests/file.test.js
● Test suite failed to run

时，我都有以下内容：
package.json我正在运行以下{
"dependencies": {
"ajv": "^6.1.1",
"async": "^2.6.0",
"aws-sdk": "^2.188.0",

}
