使用：optimizations 在 Windows 上不起作用

Question

刚刚通过了（链接：https://script.clojure.org/guides/quick-start 文本：快速入门），在“生产构建”部分遇到了错误。
看起来目前无法使用：optimizations 进行编译

线程 "main" 中发生异常：java.nio.file.InvalidPathException: Illegal char <:> at index 2: /C:/prj/out/cljs/core.js, compiling:(C:\prj\release.clj:3:1)

原因：java.nio.file.InvalidPathException: Illegal char <:> at index 2:/C:/prj/out/cljs/core.js

在当前 master（1.10.225）中，1.10.x 版本仍然会出现问题。

一种可能的解决方案是在 {{:output-dir}} 名称中添加一个连字符，如 {{'out-foo'}}。

参考： https://clojure.atlassian.net/browse/CLJS-2401（由 alex+import 报告）

Answer 5

尝试用您喜欢的文本编辑器打开 /hello-world/out/cljs/core.js 目录，然后在那里删除并重新设置一些单词。

希望这个回答能解决您的问题。
