无法在类路径中找到clojure/spec__init.class、clojure/spec.clj或clojure/spec.cljc

Question

嘿，

我想使用这个Git仓库。安装对我来说成功了，但是当我运行mvn -X exec:java时，我遇到了以下错误

config.clj文件看起来像这样

    (ns edu.upc.modelvsdocument.config
  (:use [edu.upc.modelvsdocument.utils]
        [com.rpl.specter]
        [edu.upc.modelvsdocument.schemas]
        [edu.upc.modelvsdocument.utils]
        [clojure.pprint])
  (:require [clojure.java.io :as io]
            [clojure.spec :as spec]
            [clojure.spec.test :as stest]
            [edu.upc.modelvsdocument.schemas :as t :refer :all]
            [clojure.walk :as walk]))

我读过很多关于clojure/spec/alpha__init.class的内容，但我不确定这与我遇到的问题是否有关。请向这位渴望知识的Clojure新手提供一些智慧：)

我们很乐意在#clojurians Slack中帮助您，但我认为这会涉及到大量关于您设置和基本Clojure信息的来回讨论，而且不是在这个提问网站上富有成效的用途。

好的，感谢您的建议！:)

Answer 2

我的假设是您正在使用 Clojure 1.9+，但是没有包含依赖的 spec.alpha 和 core.specs.alpha 库。

正如 Justin 在另一个答案中提到的，在 Clojurians slack 中获得交互式帮助可能更容易。
