无法使用Node-sass，bootstrap-sass加载引导程序

Question

我正在使用基于node / express的旧/新项目，其中boostrap源被痛苦地复制粘贴（并且被黑客入侵）。 我想使用bootstrap包更易于维护。 但是，在添加bootstrap-sass和node-sass之后，我遇到了这个错误：

这是错误

in /vagrant/sass/theme.scss:28:1
Error: File to import not found or unreadable: bootstrap/variables
Parent style sheet: /vagrant/sass/theme.scss
    at options.error (/vagrant/node_modules/node-sass/lib/index.js:277:32)

server.js

app.use(
  sass({
    src: __dirname + '/sass',
    dest: __dirname + '/public/css',
    prefix: '/css',
    // outputStyle: 'compressed',
    debug: true,
  })
);

我是节点的新手，来自Rails，使用sass设置bootstrap非常简单。 如果您需要有关该项目的其他文件/信息，请告诉我们。

谢谢你的帮助！

将bootstrap-sass导入到React / Webpack项目时，我遇到了类似的问题，但解决方案是相同的。 在主scss文件（theme.scss）中，您需要通过node_modules包中的相对路径减去node_modules路径段来@import个别mixins。

如果要提取单个功能，则需要更改@import "bootstrap/feature"路径，以反映要在bootstrap-sass程序包中使用的每个功能的路径。 另请注意路径中的前面的~ ，它解决了导航到SCSS文件的错误。

@import "~bootstrap-sass/assets/stylesheets/bootstrap/variables";

另一个问题是，如果您要使用字形图，则需要将$icon-font-path为指向包中的fonts文件夹，否则服务器将错误地找到这些文件。

$icon-font-path: "~bootstrap-sass/assets/fonts/bootstrap/";
@import "bootstrap-sass/assets/stylesheets/bootstrap/glyphicons";

如果你只想使用包中的所有东西，你可以设置icon-font-path并在theme.scss文件中拉入所有样式。

// Bootstrap
$icon-font-path: "~bootstrap-sass/assets/fonts/bootstrap/";
@import "~bootstrap-sass/assets/stylesheets/_bootstrap.scss";

我在angular and gulp-sass中导入bootstrap-sass时遇到了类似的问题。 在我的项目问题解决

"./node_modules/bootstrap-sass/assets/stylesheets/bootstrap/variables"
