Question

我准备了一个docker应用程序。现在，我想在服务器heroku上实现它，不幸的是在命令执行过程中返回了错误。

git push heroku master

我收到此错误消息

我的 heroku.yml 文件如下所示：

setup:
  addons:
  - plan: heroku-postgresql
build:
  docker:
    web: Dockerfile
release:
  image: web
  command:
    - python manage.py collectstatic --noinput
run:
  web: gunicorn pvb.wsgi

根据this，缩进不匹配。应该是这样

    setup:
      addons:
        - plan: heroku-postgresql
          as: database
    build:
      docker:
        web: Dockerfile
    release:
      image: web
      command:
        - python manage.py collectstatic --noinput
    run:
      web: gunicorn pvb.wsgi

将YAML转换为JSON时出错：yaml：第3行：找不到预期的密钥
