无法通过knex迁移在CircleCI中运行迁移

Question

我想创建一个由Circle CI进行集成测试的数据库，这是.config.yml Circle CI配置

    version: 2 # use CircleCI 2.0
jobs: # a collection of steps
  build: # runs not using Workflows must have a `build` job as entry point
    docker: # run the steps with Docker
      - image: circleci/node:10.15.0
        environment:
            POSTGRES_HOST: 'postgresql://postgres:password@localhost:5432/testdb'
            POSTGRES_USER: postgres
            POSTGRES_PASSWORD: password
            POSTGRES_DB: testdb
      # Specify service dependencies here if necessary
      # CircleCI maintains a library of pre-built images
      # documented at https://circleci.com/docs/2.0/circleci-images/
      - image: circleci/redis:latest
      - image: mdillon/postgis
        environment:
          POSTGRES_USER: postgres
          POSTGRES_PASSWORD: password
          POSTGRES_DB: testdb

    working_directory: ~/nodejs_typescript

    steps: # a collection of executable commands
      - checkout

      - run:
          name: update-npm
          command: 'sudo npm install -g npm@latest'

      # Download and cache dependencies
      - restore_cache: # special step to restore the dependency cache
          # Read about caching dependencies: https://circleci.com/docs/2.0/caching/
          key: dependency-cache-{{ checksum "package.json" }}

      - run:
          name: install-npm-wee
          command: npm install

      - save_cache:
          name: Save-Cache
          paths:
            - './node_modules'
          key: dependency-cache-{{ checksum "package.json"}}

      - run:
          name: install-global-knex
          command: sudo npm install -g knex

      - run: sudo apt-get update
      - run: sudo apt-get install postgresql-client-9.6 -y

      - run: 
         name: Create database
         command: psql -U postgres -h localhost -p 5432 -tc "SELECT 1 FROM pg_database WHERE datname = 'testdb'" | grep -q 1 || psql -U postgres -h localhost -p 5432 -c "CREATE DATABASE testdb"

      - run:
          name: Knex Migrations
          command: knex migrate:latest --knexfile src/knexfile.ts --env test
          environment:
            NODE_ENV: test

      - run:
          name: Knex seeds
          command: knex seed:run --knexfile src/knexfile.ts --env test
          environment:
            NODE_ENV: test

      - run: # run tests
          name: test
          command: npm run test
          environment:
            NODE_ENV: test

但是运行命令knex migrate:latest --knexfile src/knexfile.ts --env test时构建已损坏，这是错误

使用环境：测试 错误：getaddrinfo ENOTFOUND postgresql：// postgres：password @ localhost：5432 / testdb postgresql：// postgres：password @ localhost：5432 / testdb：5432     在GetAddrInfoReqWrap.onlookup上（作为完成时）（dns.js：57：26） 以代码1退出

我不知道为什么我不能从knex运行迁移，有人可以帮我吗
