我正在学习使用 node 作为前端构建工具,并且正在努力将引导程序包含到 css 捆绑文件中以包含在网页中。
我有一个用于 LESS 的加载器和一个用于 CSS 的加载器,以及用于 FONTS 的加载器,并且要求我自己的源代码中的任何一个似乎都可以正确地将 CSS 转换为我的包文件,但是只要我
require('bootstrap/dist/css/bootstrap.css')
或者
require('../../node_modules/bootstrap/dist/css/bootstrap.css')
我在 webpack 期间收到以下错误:
ERROR in ./~/bootstrap/dist/css/bootstrap.css?root=/~/bootstrap/dist/
Module parse failed: <my project root>/node_modules/bootstrap/dist/css/bootstrap.css?root=/node_modules/bootstrap/dist/ Unexpected token (7:5)
You may need an appropriate loader to handle this file type.
SyntaxError: Unexpected token (7:5)
我从包中检查了 bootstrap.css,第 7 行,char5 似乎是 html 和 { 文件中第一个 css 规则之间的“”空间,这是一个完全有效的 CSS 块注释...?我什至可以将该文件的全部内容复制到我的一个本地源文件(common/style.less)中,它会很好地解析并包含在包中。我根本无法从 node_modules 位置包含它。为什么?
我的 app.js 入口点如下所示:
import 'babel-polyfill';
// common frameworks
require('expose?$!jquery');
require('expose?jQuery!jquery');
require('bootstrap/dist/js/bootstrap.js');
// common styles
require('bootstrap/dist/css/bootstrap.css');
require('./common/style.less');
// common images
var images = require.context('./common/images/', true, /.*\.(png|gif|bmp|jpg|jpeg|ico)$/);
images.keys().forEach(images);
// modules
require('./modules/landing');
