我的project.clj文件看起来像这样
(defproject cljs-template "0.1.0-SNAPSHOT"
:description "FIXME: write this!"
:url "http://example.com/FIXME"
:dependencies [[org.clojure/clojure "1.4.0-beta4"]
[noir-cljs "0.3.0"]
[fetch "0.1.0-alpha2"]
[noir "1.3.0-beta2"]
[org.clojure/core.cache "0.5.0"]
[com.datomic/datomic "0.1.3142"
:exclusions [org.slf4j/slf4j-nop org.slf4j/slf4j-log4j12]]
[ch.qos.logback/logback-classic "1.0.1"]]
:plugins [[lein-swank "1.4.3"]]
;:cljsbuild {:builds [{}]}
:main ^{:skip-aot true} cljs-template.server)
我的/src/cljs_template/server.clj开头如下：
(ns cljs-template.server
(:require [noir.server :as server]
[noir.cljs.core :as cljs]
[cljs-template.tree :as tree])
(:use [datomic.api :only [db q] :as d]))
然后我启动swank，在其中运行（in-ns'cljs-template.server），将光标移动到（ns）函数调用的末尾，并尝试使用Ctrl-运行（ns）方法x Ctrl-e。当我这样做时，我收到以下错误。
No message.

我做错了什么？如何使用swank / slime在我的emacs中使用datomic。
答案 0 :(得分：4)
原来我正在执行错误的命令。
我正在运行lein deps并收到以下错误。
...
Try downloading the file manually from the project website.
Then, install it using the command:
mvn install:install-file -DgroupId=com.datomic -DartifactId=datomic -Dversion=0.1.3157 -Dpackaging=jar -Dfile=/path/to/file
Alternatively, if you host your own repository you can deploy the file there:
mvn deploy:deploy-file -DgroupId=com.datomic -DartifactId=datomic -Dversion=0.1.3157 -Dpackaging=jar -Dfile=/path/to/file -Durl=[url] -DrepositoryId=[id]
Path to dependency:
1) org.apache.maven:super-pom:pom:2.0
2) com.datomic:datomic:jar:0.1.3157
我看到下载的数据组代码中的README文件也包含了向我的mvn添加datomic的提及。当然（这是愚蠢的部分）我认为他们说的是同样的事情。
莱恩会告诉你应该执行mvn install:install-file -DgroupId=com.datomic -DartifactId=datomic -Dversion=0.1.3157 -Dpackaging=jar -Dfile=/path/to/file
README说你应该执行
mvn install:install-file -DgroupId=com.datomic -DartifactId=datomic -Dfile=datomic-${DATOMIC-VERSION}.jar -DpomFile=pom.xml
您是否注意到README指令还包含一个pom.xml文件？我也不！是的，这很重要。
无论如何，请务必同时包含pom.xml文件。如果您尝试将datomic 0.1.3157添加到mvn存储库，则可以在下载的datomic目录中执行以下命令。
mvn install:install-file -DgroupId=com.datomic -DartifactId=datomic -Dfile=datomic-0.1.3157.jar -DpomFile=pom.xml
答案 1 :(得分：3)
我调试swank问题的常见疑问是：
mvn install:install-file -DgroupId=com.datomic -DartifactId=datomic -Dfile=datomic-${DATOMIC-VERSION}.jar
