我正在尝试通过 docker-compose 安装 CKAN：http ://docs.ckan.org/en/2.8/maintaining/installing/install-from-docker-compose.html

如果我尝试构建：

docker-compose up -d --build

我不断得到：

ERROR: for db  Cannot create container for service db: no such file or directory
ERROR: compose.cli.main.main: Encountered errors while bringing up the project.

使用详细标志，我得到：

compose.cli.verbose_proxy.proxy_callable: docker inspect_image <- (u'docker_db')
urllib3.connectionpool._make_request: http://localhost:None "GET /v1.25/images/docker_db/json HTTP/1.1" 200 None

我有一群人,他们每个人都有朋友名单和敌人名单.我想把它们排成一行(桌子上没有圆圈),所以没有敌人,只有朋友彼此相邻.

输入示例:https://gist.github.com/solars/53a132e34688cc5f396c

我想我需要使用图形着色来解决这个问题,但我不确定如何 - 我想我必须省略朋友(或敌人)列表以使其更容易并映射到图表.

有谁知道如何解决这些问题,并告诉我,如果我走在正确的道路上？

代码示例或在线示例也不错,我不介意编程语言,我通常使用Ruby,Java,Python,Javascript

非常感谢你的帮助!

我有以下设置,我想要做的是在移动地图时更新标记:

https://gist.github.com/277894809fe04cbc29c7

json端点返回例如:

[{"_id":"4ecc19ca8de17b2f0f000001","latitude":47.413358,"location":[47.413358,9.744583],"longitude":9.744583,"name":"d2"},{"_id":"4ecc14e68de17b2924000001","latitude":47.413417,"location":[47.413417,9.744417],"longitude":9.744417,"name":"another"}]

但移动地图时出现以下错误:

Uncaught RangeError: Maximum call stack size exceeded
I.get
a.(anonymous function)
tB.(anonymous function).zoomRange_changed
mf
I.set
(anonymous function)
tB.(anonymous function).zoomRange_changed
mf
I.set
......

不知道是什么导致这种情况,我把各种来源的样本放在一起,不得不适应很多,因为它似乎改变了很多方法.不确定我是否错过了什么,如果有人能指点我,我会很高兴

非常感谢,Christoph

我正在执行一个查询，ActiveRecord::Base.connection.exec_query()但继续将整数作为字符串获取，如下所示：

ActiveRecord::Base.connection.exec_query(query)
