Question

我正在努力学习clojure.spec。在启动构建工具中设置clojure项目时，我在获取clojure.spec.alpha时遇到以下错误。

Compiling ClojureScript...
• js/app.js
No such namespace: clojure.spec.alpha, could not locate clojure/spec/alpha.cljs, clojure/spec/alpha.cljc, or Closure namespace "clojure.spec.alpha" in f
ile src/cljs/flowparser/app.cljs

我的启动配置如下：

我的主要app.cljs文件如下：

(ns flowparser.app
  (:require [clojure.spec.alpha :as spec]))

(defn init []
  "Hello World")

正如我刚刚开始clojure时，对这类问题的任何建议都会有很大帮助。

由于

Answer 1

你在特别棘手的时刻拿起规格。 Clojure 1.9.0-alpha16刚刚将名称空间从clojure.spec更改为clojure.spec.alpha。

ClojureScript在master上进行了相同的更改，但尚未发布新版本。因此，对于ClojureScript＆lt; = 1.9.521，您需要使用clojure.spec作为您需要的命名空间。

Answer 2

可能需要更新版本的spec.alpha才能解决您的问题。

尝试将此添加到您的依赖项

 [org.clojure/spec.alpha "0.1.108"]

维护者的解释是https://groups.google.com/d/msg/clojure/10dbF7w2IQo/s5kUM4tCAAAJ

没有这样的命名空间：clojurescript项目设置中的clojure.spec.alpha
