Twitter bootstrap – Unable to load bootstrap with Node-sass, bootstrap-sass

I’m on a old/new project based on node/express where boostrap source was painfully copy-pasted (and hacked).
I want to use bootstrap package to be more maintainable. But, after adding bootstrap-sass and node-sass, I face this error:

Here’s the error

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,

);

I’m new to node, coming from Rails where setupping bootstrap with sass was really easy. Let me know if you need additional files/info about the project.

Thank you for help!

    I had a similar issue when importing bootstrap-sass to a React/Webpack project, but the solution is the same. In your main scss file (theme.scss), you need @import individual mixins via the relative paths inside the node_modules package minus the node_modules path segment.

    If you are pulling individual features then you need to change the @import "bootstrap/feature" path to reflect the path of every feature you want to use in the bootstrap-sass package. Also note the preceding ~in the path, which resolves an error for navigating the to SCSS files.

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

    Another gotcha, if you are pulling in the glyphicons you are going to need to set the $icon-font-path to point to the fonts folder in the package, or else the server will error out for finding those files.

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

    If you just want to use everything in the package, you can just set the icon-font-path and pull in all the styles like so in your theme.scss file.

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