根据文档，应该只import编辑CSS文件。
我刚开始webpack尝试导入CSS文件，但收到有关缺少模块的消息：

@ ./webpack/entry.js 1:0-21
webpack遇到以下情况webpack.config.js：
const path = require('path');
module.exports = {
entry: path.join(__dirname, 'webpack/entry.js'),
output: {
path: path.join(__dirname, 'dist'),
filename: 'build.js'
},
module: {
loaders: [
{
test: /\.js$/,
loader: 'babel-loader',
exclude: /node_modules/
}
],
rules: [{
test: /\.css$/,
use: [ 'style-loader', 'css-loader' ]
}]
}
}
我最初以为（使用之前--display-error-details）这是由于路径结构存在一些问题（特别是正斜杠与反斜杠），但后来又移到navbar.css了文件夹的根目录中webpack-同样的问题。
详细的错误表明，正在搜索CSS文件nodes_module（通过所有目录树进行了查找）。为什么？然后，我应该如何导入webpack/static/css/myfile.css相对于位置的文件webpack.config.js？
注意：尝试require而不是尝试时存在相同的问题import
您必须像导入任何JavaScript模块一样导入它们。这意味着，如果导入的文件既不是相对路径（以../或开头./），也不是绝对路径（以开头/），则将其解析为模块。默认情况下，webpack将在node_modules目录（当前目录和所有父目录）中查找模块。这与Node.js使用的行为相同。
要导入webpack/static/css/myfile.css，webpack/entry.js您必须使用相对路径。
import './static/css/myfile.css';
如果您不想使用相对路径，则resolve.modules可以使用或更改webpack用于查找模块的目录resolve.alias。
在您的webpack配置中，您还定义了module.rules和module.loaders。当webpack看到module.rules它module.loaders完全忽略时，您babel-loader将不会被使用。您只能使用module.rules。
module: {
rules: [
{
test: /\.js$/,
loader: 'babel-loader',
exclude: /node_modules/
},
{
test: /\.css$/,
use: ['style-loader', 'css-loader']
}
]
}
