图3兼容Python 3吗？

Question

我有一个django应用程序运行python3.4，我想使用图来帮助为我的应用程序的组件设置托管容器。当我运行fig up时，会得到以下错误：

Recreating app_db_1...
Recreating app_search_1...
Creating app_web_1...
Traceback (most recent call last):

这是因为与Python 3不兼容吗？也就是说，我有没有办法用无花果来帮助我的应用程序的构建，还是我运气不好？无花果是用自制的。

这是我的无花果文件：

db:
    image: kartoza/postgis
web:
    build: .
    command: python manage.py runserver:8000
    volumes:
      - .:/code
    ports:
      - "8000:8000"
    links:
      - db
      - search
    environment:
      - ALLOWED_HOSTS:
      - STRIPE_CLIENT_ID:
      - STRIPE_CLIENT_SECRET:
      - GOOGLE_API_KEY:
search:
    image: dockerfile/elasticsearch
    links:
      - db

Answer 1

问题不在于Python的版本，而在于我的无花果文件。

图文件不应该在环境变量前面有破折号。更正后的无花果文件如下：

db:
    image: kartoza/postgis
web:
    build: .
    command: python manage.py runserver:8000
    volumes:
      - .:/code
    ports:
      - "8000:8000"
    links:
      - db
      - search
    environment:
      ALLOWED_HOSTS:
      STRIPE_CLIENT_ID:
      STRIPE_CLIENT_SECRET:
      GOOGLE_API_KEY:
search:
    image: dockerfile/elasticsearch
    links:
      - db

图3是用Python2.7编写的工具，在Python3中不可用，但这并不意味着它与Python3项目不兼容，因为它没有集成到项目代码中。它是一个单独的工具，由python2.7单独运行。

Answer 2

包名包含一个提示：fig-1.0.1-py2.7.egg

似乎您安装了图2的Python2版本。尝试从Python3环境中使用pip install fig安装。
