我按照 getbootstrap.com 上的说明进行操作,认为一切都会正常进行。它不是到目前为止:
一切似乎都很好,直到我尝试加载页面,此时我的 Express.js 应用程序抛出错误
[[sass] error: File to import not found or unreadable: ~bootstrap/scss/bootstrap.
Parent style sheet: .../sass/app.scss at options.error (.../node-sass/lib/index.js:291:26)
我已经尝试过 npm install,重新启动我的服务器,查看 Google,StackOverflow(是的,我知道有很多类似的问题,但没有一个回答我的问题),Bootstrap 4 GitHub 问题页面,到目前为止我还没有能够想出答案。
会不会是我把依赖装错地方了? (开发而不是生产或相对)
为什么我会收到此错误??
我的 webpack.config.js 文件看起来像这样……
module.exports = {
entry: './src/index.js',
output: {
path: __dirname + '/public',
filename: 'bundle.js'
},
module: {
loaders: [
{
test: /\.json$/,
loader: 'json-loader'
},
{
test: /\.js$/,
loader: 'babel-loader'
},
{
test: /\.(scss)$/,
use: [{
loader: 'style-loader', // inject CSS to page
}, {
loader: 'css-loader', // translate CSS into CommonJS modules
}, {
loader: 'postcss-loader', // run post CSS actions
options: {
plugins: function () { // post css plugins, can be exported to postcss.config.js
return [
require('precss'),
require('autoprefixer')
];
}
}
}, {
loader: 'sass-loader' // compile Sass to CSS
}]
}
]
}
};

在 app.scss 里面我有
@import "custom";
@import "~bootstrap/scss/bootstrap";

当 Sass 由它自己的 CLI 预编译时,它自己处理
@imports
,因此有时不理解~
符号。因此,您可以首先导入"node_modules/bootstrap/scss/bootstrap";
并将~
node_modules/
。
