Sass / css不会在cloud9轮询 - 回退错误中呈现

Question

我的sass或css文件正在呈现，我收到了这个池回退错误。

有谁知道这个错误意味着什么？

Answer 1

正如错误消息中所述，找不到文件 styles.s c ss ：

error No such file or directory @ rb_sysopen - styles.scss

您的目录中似乎有一个名为 styles.sass 的文件，因此您可以尝试将命令更改为以下内容：

$ sass --watch styles.sass:styles.css

此外，似乎有未构建的扩展，您可以尝试使用错误消息中指定的命令进行修复（下面的几个示例）

Try: gem pristine executable-hooks --version 1.3.2
Try: gem pristine ffi --version 1.9.23
Try: gem pristine gem-wrappers --version 1.2.7
