Clojurescript快速入门问题-构建失败 [英] Problems with Clojurescript quickstart -- build fails

问题描述

我正在尝试遵循 Clojurescript快速入门

我已经按照快速入门指南中的说明下载了Clojurescript jar。我已经验证它具有适当的大小（大约19M）。我已经创建了文件。但是当我尝试使用以下命令进行构建时：

I have downloaded the Clojurescript jar as described in the Quick-Start guide. I have verified that it has the appropriate size (about 19M). I have created the files. But when I try to build using the command:

java -cp cljs.jar:src clojure.main build.clj

Java返回以下堆栈跟踪：

Java returns the following stacktrace:

Exception in thread "main" java.io.FileNotFoundException: Could not locate cls/build/api__init.class or cls/build/api.clj on classpath., compiling:(/Users/jnedzel/Documents/prj/closurescript/quickstart/hello_world/build.clj:1:1)

Caused by: java.io.FileNotFoundException: Could not locate cls/build/api__init.class or cls/build/api.clj on classpath.

有什么想法吗？

推荐答案

TL; DR ： build.clj

从快速入门开始，文件 build.clj 应具有以下内容：

As of the Quick-Start, the file build.clj should have the following content:

(require 'cljs.build.api)

(cljs.build.api/build "src" {:output-to "out/main.js"})

错误消息显示无法找到cls / build /api__init.class 。当clojure编译器编译ns时，将生成名为 my / domain / lib__init.class 的加载程序类文件。在给定（需要'my.domain.lib）的情况下，将加载该类。

The error message says Could not locate cls/build/api__init.class. When the clojure compiler compiles a ns, a loader classfile is generated with the name my/domain/lib__init.class. That's the class that will be loaded given (require 'my.domain.lib).

cljs.build.api ，即为 cljs /build/api__init.class 。但是它正尝试加载 cls /build/api__init.class ，因此您在这里有错字。

In the case of cljs.build.api, that would be cljs/build/api__init.class. But it is trying to load cls/build/api__init.class instead, so you have a typo there.
