Clojure 无法在此上下文中解析符号:defrel
我无法让clojure从core.logic库中识别defrel。因此,在使用lein(和compojure)设置了一个项目并让core.logic运行*后,我尝试了一个使用defrel的简单示例。下面是生成的标题,包括:use clojure.core.logic和失败的行(请参阅我想要运行的完整示例) lein 2.0生成的project.clj文件如下:Clojure 无法在此上下文中解析符号:defrel,clojure,clojure-core.logic,Clojure,Clojure Core.logic,我无法让clojure从core.logic库中识别defrel。因此,在使用lein(和compojure)设置了一个项目并让core.logic运行*后,我尝试了一个使用defrel的简单示例。下面是生成的标题,包括:use clojure.core.logic和失败的行(请参阅我想要运行的完整示例) lein 2.0生成的project.clj文件如下: (defproject hw2 "0.1.0-SNAPSHOT" :description "FIXME: writ
(defproject hw2 "0.1.0-SNAPSHOT"
:description "FIXME: write description"
:url "http://example.com/FIXME"
:dependencies [[org.clojure/clojure "1.5.1"]
[compojure "1.1.6"]
[org.clojure/core.logic "0.8.5"]
]
:plugins [[lein-ring "0.8.10"]]
:ring {:handler hw2.handler/app}
:profiles
{:dev {:dependencies [[javax.servlet/servlet-api "2.5"]
[ring-mock "0.1.5"]]}})
如果我运行lein ring server,我会得到:
ian@U11-VirtualBox:~/cljtest/test1/hw2$ lein ring server
Exception in thread "main" java.lang.RuntimeException: Unable to resolve symbol: defrel in this context, compiling:(hw2/handler.clj:21:1)
根据lein的说法,所有内容都是最新的,即:lein deps相应地下载所有内容,等等。O/S是Ubuntu 13
从命令行:
ian@U11-VirtualBox:~/cljtest/test1/hw2$ lein repl

再次运行*工作正常
我已经试过了,但找不到任何有效的方法。:

此功能也已从中消失。我不知道它现在是什么/如果是。似乎它现在是
(pldb/db rel man p)
和(pldb/db[man'Bob][man'John])
这个函数也从数据库中消失了。我不知道它现在是什么/如果是。似乎它现在是(pldb/db rel man p)
