咕噜.js，警告：无法写入"src"文件(错误代码：EISDIR)

Question

我有一个用CoffeeScript写的Gruntfile，当cssmin任务运行时，我不断得到(Error code: EISDIR)。以详细模式运行任务后，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运行后创建，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？

另外，这是纵容的整个咕噜声文件。

Answer 1

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。这不可能是想要的结果吗？

您需要为 cssmin 任务指定一个名称，因为它是一个多任务。有关其他信息，请参阅 Grunt 文档。

将您的咕噜声配置更改为

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

Answer 2

使用 NodeJS 4.2.2 和 Grunt 0.4.5

，

当编译的文件名与现有目录相同时，我遇到了 EISDIR 写入错误。它们都处于同一层次结构级别。重命名解决了这个问题。

Answer 3

似乎，src 指向目录。尝试将/** 添加到路径末尾。

assets/z.styles.concat.css.liquid/**
