mac 安装sass命令行编译环境

1.安装ruby

    使用homebrew安装ruby。

    命令：brew install ruby

2.在~/.bash_profile中加入ruby的环境变量，替换系统本身ruby

export PATH=/usr/local/opt/ruby/bin:/usr/local/lib/ruby/gems/2.5.0/bin:$PATH
export LDFLAGS=-L/usr/local/opt/ruby/lib
export CPPFLAGS=-I/usr/local/opt/ruby/include
export PKG_CONFIG_PATH=/usr/local/opt/ruby/lib/pkgconfig

3.使用ruby的包管理gem安装sass相关依赖

gem install sass
gem install compass

4.即可是哟sass命令编译scss文件

sass src/theme/default.scss src/theme/default.css

编译前：

// 表单

    .ibiz-form-button {
        text-align: center;
    }

    .ibiz-form-item {

        .stars {
