我试图从lein new compojure clojure-lice
运行样板项目。
当我运行lein ring server
时,会收到以下错误提示:
Exception in thread "main" java.lang.RuntimeException: No reader function for tag namespace
我的
project.clj
(defproject clojure-lice "0.1.0-SNAPSHOT"
:description "FIXME: write description"
:url "http://example.com/FIXME"
:min-lein-version "2.0.0"
:dependencies [[org.clojure/clojure "1.8.0"]
[compojure "1.5.1"]
[ring/ring-defaults "0.2.1"]]
:plugins [[lein-ring "0.9.7"]]
:ring {:handler clojure-lice.handler/app}
:profiles
{:dev {:dependencies [[javax.servlet/servlet-api "2.5"]
[ring/ring-mock "0.3.0"]]}})
我的
core.clj
:(ns clojure-lice.handler
(:require [compojure.core :refer :all]
[compojure.route :as route]
[ring.middleware.defaults :refer [wrap-defaults site-defaults]]))
(defroutes app-routes
(GET "/" [] "Hello World")
(route/not-found "Not Found"))
(def app
(wrap-defaults app-routes site-defaults))
我的系统统计:
java version "9.0.1"
Java(TM) SE Runtime Environment (build 9.0.1+11)
Java HotSpot(TM) 64-Bit Server VM (build 9.0.1+11, mixed mode)
Leiningen 2.8.0 on Java 9.0.1 Java HotSpot(TM) 64-Bit Server VM
Clojure 1.8.0
OSX 10.12.6
最佳答案
尝试将Leiningen降级为2.7.1:
lein upgrade 2.7.1
这是Leiningen 2.8.0中的回归。请参见https://github.com/technomancy/leiningen/issues/2328。
