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

Question

我正在尝试学习clojure.spec。在通过启动构建工具设置clojure项目时，在需要clojure.spec.alpha时出现以下错误。

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:

        (target :dir #{"docs"})))

我的主要app.cljs文件如下:

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

(defn init []
  "Hello World")

由于我刚开始使用 clojure，因此有关此类问题的任何建议将大有帮助。

谢谢

您在一个特别棘手的时刻获取规范。 Clojure 1.9.0-alpha16刚刚将 namespace 从clojure.spec更改为clojure.spec.alpha。

ClojureScript在master上进行了等效的更改，但尚未发布新版本。因此，对于ClojureScript <= 1.9.521，您需要改为使用clojure.spec作为所需的 namespace 。
