javascript - grunt sass 任务由于 bourbon 包而产生错误

Question

我正在为我的项目编写一个 grunt 任务文件。我已经在其中定义了 sass 任务并安装了所有必需的依赖项。我可以在 friend 的计算机上运行相同的 gruntfile，但在我的计算机上，sass 任务会产生此错误。

Running "sass:dist" (sass) task
Syntax error: Invalid CSS after "      webkit-image": expected ")", was ": -webkit- + $p..."
        on line 21 of /home/chitrank/Documents/shaastr/frontend/frontend/frontend/app/minovate/bower_components/bourbon/dist/helpers/_linear-angle-parser.scss
        from line 10 of /home/chitrank/Documents/shaastr/frontend/frontend/frontend/app/minovate/bower_components/bourbon/dist/_bourbon.scss
        from line 6 of app/sass/main.scss
  Use --trace for backtrace.
Warning: Exited with error code 1 Use --force to continue.

Aborted due to warnings.

由于这个错误，我无法执行 sass 任务，需要在我 friend 的电脑上执行。我还添加了我的 Gruntfile.js，以便更好地了解我的 grunt 任务是什么以及它是如何工作的，请看一下。

如果有人解决过这个问题，请告诉我。

Answer 1

This discussion说这个问题是由 Sass 和 Bourbon 的版本不兼容引起的。

Bourbon 4 至少需要 Sass 3.3，因此如果您运行的是较低版本，则需要将 Bourbon 降级到 3.x 或升级 Sass
