npm - 萨斯--watch : could not find option named "watch"

Question

很简单，但是在网上找不到任何答案!在我的Mac上全局安装sass(npm install -g sass)。

这可以按预期工作:

sass style.scss style.css

然后我尝试:

sass --watch style.scss:style.css

并获得:

Could not find an option named "watch".

Usage: sass <input> [output]

    --[no-]stdin          Read the stylesheet from stdin.
    --[no-]indented       Use the indented syntax for input from stdin.
-I, --load-path=<PATH>    A path to use when resolving imports.
                      May be passed multiple times.

-s, --style=<NAME>        Output style.
                      [expanded (default), compressed]

-c, --[no-]color          Whether to emit terminal colors.
-q, --[no-]quiet          Don't print warnings.
--[no-]trace          Print full Dart stack traces for exceptions.
-h, --help                Print this usage information.
    --version             Print the version of Dart Sass.

我想念什么？

谢谢!!

最后，我放弃了上面尝试过的sass，转而使用webpack寻求解决方案。

我尝试过的另一个选择是使用node-sass。
