coffeescript - Grunt.js，警告 : Unable to write "src" file (Error code: EISDIR)

Question

我有一个 Gruntfile写于 CoffeeScript我不断收到 (Error code: EISDIR)当cssmin任务运行。在详细模式下运行任务后，我得到以下信息:

Running "cssmin" task

Running "cssmin:src" (cssmin) task
Verifying property cssmin.src exists in config...OK
Files: assets/z.styles.concat.css.liquid -> src
Options: report=false
Reading assets/z.styles.concat.css.liquid...OK
Writing src...ERROR
Warning: Unable to write "src" file (Error code: EISDIR). Use --force to continue.

这是我的 cssmin 任务:

 cssmin: 
        src: 'assets/z.styles.concat.css.liquid'
        dest: 'assets/styles.min.css.liquid'

z.styles.concat.css.liquid在 concat 之后创建运行并成功输出到assets文件夹。 src 属性中列出的路径是正确的。

知道什么可能会引发错误吗？

此外，为了方便起见，这里是整个 gruntfile。

在你的输出中，Grunt 试图运行 cssmin:src任务，然后它尝试写入源文件。这不会是想要的结果吧？

您需要为 cssmin 任务指定一个名称，因为它是一个多任务。见 Grunt documentation了解更多信息。

将您的 grunt 配置更改为

cssmin:
    minify:
        src: 'assets/z.styles.concat.css.liquid'
        dest: 'assets/styles.min.css.liquid'
