无法运行 ClojureScript Hello World 程序，"Error building classpath. Error reading edn."

Question

我正在尝试使用 the ClojureScript QuickStart page 中的指令运行一个简单的 ClojureScript hello world 程序，但是当我运行命令 clj -M --main cljs.main --compile hello-world.core --repl （在 hello-world项目文件夹），我收到此错误：Error building classpath. Error reading edn. Invalid number: 1.10.758 (/some_path_to_/deps.edn).

ClojureScript 代码为：

(ns hello-world.core)

(println "Hello world!")

和 deps.edn 文件包含： {:deps {org.clojure/clojurescript {:mvn/version 1.10.758}}}

如何摆脱这个错误？

您需要在版本号周围加上双引号。示例文件：

{:deps    {
           org.clojure/clojure             {:mvn/version "1.10.2-alpha1"}
           org.clojure/clojurescript       {:mvn/version "1.10.764"}

           com.bhauman/figwheel-main       {:mvn/version "0.2.11"}
           com.bhauman/rebel-readline-cljs {:mvn/version "0.1.4"}

           re-frame                        {:mvn/version "1.0.0"}
           reagent                         {:mvn/version "0.10.0"}
           reagent-utils                   {:mvn/version "0.3.3"}

           org.clojure/spec.alpha          {:mvn/version "0.2.176"}
           prismatic/schema                {:mvn/version "1.1.12"}
           tupelo                          {:mvn/version "20.07.21"}
           }

 :paths   ["src" "test" "target" "resources"]

 :aliases {
           :ancient {:main-opts  ["-m" "deps-ancient.deps-ancient"]
                     :extra-deps {deps-ancient {:mvn/version "RELEASE"}}}
           :fig     {:main-opts ["-m" "figwheel.main"]}
           :dev     {:main-opts ["-m" "figwheel.main" "--build" "dev" "--repl"]
                     ; :extra-deps {tupelo {:local/root "/Users/r634165/tupelo/target/uberjar/tupelo-0.9.XXXXX-standalone.jar"}}
                     }
           }
 }

我最近没有使用 CLJS，但上面显示了正确的形式。
