Sass -- 在 Linux 上观察错误

Question

我正在运行 sass --watch 将我的 css 文件处理为 scss 文件。我不确定它是否是这样工作的，但我已经导航到终端中的文件夹，并运行了以下命令：

~/Documents/Website Development/Kedanco/kedanco-website/assets$ sass --watch sass:css

以下是错误信息：

我熟悉 Ruby & Rails，但我没有在这个网站上使用它，它只是一个普通的静态网站。知道目标文件夹是关闭还是我错误地使用了 sass 命令？

Answer 1

sass --watch <input folder>:<output folder>

sass-watch 监视一个目录，当输入目录中的 scss 文件被添加/更改/删除时，这些更改会反映在输出目录中已编译的 css 文件中。
