docker-compose 错误 Unicode 对象必须在散列之前进行编码

Question

我从几天开始就开始使用 docker，我想创建一个包含多个容器的新项目，所以我尝试了 docker-compose，但是当我尝试启动 docker-compose run river 时，我有这个堆栈跟踪：

Traceback（最近一次调用最后一次）：

  File "/bin/docker-compose", line 9, in <module>
    load_entry_point('docker-compose==1.3.0', 'console_scripts', 'docker-compose')()
  File "/usr/lib/python3.4/site-packages/compose/cli/main.py", line 31, in main
    command.sys_dispatch()

    previous_container=previous_container,
  File "/usr/lib/python3.4/site-packages/compose/service.py", line 510, in _get_container_create_options
    config_hash = self.config_hash()
  File "/usr/lib/python3.4/site-packages/compose/service.py", line 398, in config_hash
    return json_hash(self.config_dict())
  File "/usr/lib/python3.4/site-packages/compose/utils.py", line 8, in json_hash
    h.update(dump)
TypeError: Unicode-objects must be encoded before hashing

这是我的 docker-compose.yml ：

river:
  build: .
  volumes: ./code
  command: python main/main.py
  links:
    - es
    - db
kibana:
  image: kibana
  ports:
    - "5601:5601"
  links:
    - es
db:
  image: mysql
  ports:
    - "3306:3306"
es:
  image: elasticsearch
  ports:
    - "9002:9002"

编辑

这是我的 Dockerfile

FROM python:3.4

RUN mkdir /code
WORKDIR /code
ADD requirements.txt /code/
RUN pip install -r requirements.txt
ADD . /code/

感谢您以后的帮助:)

docker-compose 不支持 python3。您需要使用python2.7运行并安装它。
