我的 sass 或 css 文件正在渲染，我得到了这个池化后备错误。

有谁知道这个错误是什么意思？

    carlagoncalves:~/workspace (master) $ node app.js
    carlagoncalves:~/workspace (master) $ sass --watch styles.scss:styles.css

正如它在错误消息中所说，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来修复（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
