Html 在引导中导入modal.less

我正在尝试使用bootstrap（v3.3.7）在我的项目中导入modals.less文件

下面是bootstrap.less代码：

 /*!

 * Licensed under MIT (https://github.com/twbs/bootstrap/blob/master/LICENSE)
 * Custom file
 */

 // Core variables and mixins
@import "variables.less";
@import "mixins.less";


// Core CSS
@import "scaffolding.less";
@import "grid.less";
@import "forms.less";
@import "buttons.less";

// Components
@import "modals.less";
@import "navs.less";
@import "dropdowns.less";
@import "popovers.less";


// Utility classes
@import "utilities.less";
@import "responsive-utilities.less";

但它在导入时抛出了一个错误

消息：'。未定义转换

这是哪一行：

// When fading in the modal, animate it to slide down
  &.fade .modal-dialog {
    .translate(0, -25%);
    .transition-transform(~"0.3s ease-out");
  }

我是否还需要导入我不知道的任何其他依赖项才能使用modal

编辑：

// Mixins

// Utilities

@import "mixins/hide-text.less";

通过上述评论进一步调查后，问题似乎是

@import“mixins/vendor prefixes.less”

在

mixins.less

文件中被注释掉。我建议取消该行的注释。

您的

mixins.less

是否有

@import“mixins/vendor prefixes.less”行？@JosephMarikle我刚检查过，mixins文件夹中没有
供应商前缀。更少的
文件。否但您正在运行
v3.3.7
？它应该在那里：我以定制的方式使用它，所以不同时使用所有文件。然后我建议您将该文件添加到mixins文件夹中，并添加
@import“mixins/vendor prefixes.less”。通常它会出现在“it's working now”中的
//Utilities
注释下，我看到所有的转换和其他规则都是在这个较少的文件中定义的。
