我刚刚下载了一个intializr生成的Bootstrap版本.我还安装了SimpLESS,以避免不得不手动重新编译我的LESS文件并避免使用浏览器内编译器.但是,SimpLESS拒绝在我的目录中编译非常基本的style.css文件.它吐了：
Result of expresiin style.less on 'e.message' [undefined] is not an object.
注意：“表达式”确实拼写为上面显示的方式.
我的style.less文件目前看起来像这样：
@import "bootstrap/bootstrap.less";
body {
padding-top: 60px;
padding-bottom: 40px;
}
@import "bootstrap/responsive.less";
解决方法
我遇到了同样的问题,我的解决方法是没有嵌套的@imports.我在Win7上使用SimpLESS 1.4和Bootstrap 2.1.0,如果你的style.less文件看起来像这样：
// CSS Reset @import "reset.less"; // Core variables and mixins @import "variables.less"; // Modify this for custom colors,font-sizes,etc @import "mixins.less"; // Grid system and page structure @import "scaffolding.less"; @import "grid.less"; @import "layouts.less"; // Base CSS @import "type.less"; @import "code.less"; @import "forms.less"; @import "tables.less"; // Components: common @import "sprites.less"; @import "dropdowns.less"; @import "wells.less"; @import "component-animations.less"; @import "close.less"; // Components: Buttons & Alerts @import "buttons.less"; @import "button-groups.less"; @import "alerts.less"; // Note: alerts share common CSS with buttons and thus have styles in buttons.less // Components: Nav @import "navs.less"; @import "navbar.less"; @import "breadcrumbs.less"; @import "pagination.less"; @import "pager.less"; // Components: Popovers @import "modals.less"; @import "tooltip.less"; @import "popovers.less"; // Components: Misc @import "thumbnails.less"; @import "labels-badges.less"; @import "progress-bars.less"; @import "accordion.less"; @import "bootstrap/carousel.less"; @import "bootstrap/hero-unit.less"; // Utility classes @import "utilities.less"; // Has to be last to override when necessary //Needed if using fixed navbar body { padding-top: 60px; padding-bottom: 40px; } .sidebar-nav { padding: 9px 0; } // RESPONSIVE CLASSES // ------------------ @import "responsive-utilities.less"; // MEDIA QUERIES // ------------------ // Large desktops @import "responsive-1200px-min.less"; // Tablets to regular desktops @import "responsive-768px-979px.less"; // Phones to portrait tablets and narrow desktops @import "responsive-767px-max.less"; // RESPONSIVE NAVBAR // ------------------ // From 979px and below,show a button to toggle navbar contents @import "responsive-navbar.less";
