我正在使用webpack@2.2.0-rc.3
和extract-text-webpack-plugin@2.0.0-beta.4
,我有以下webpack配置:
var path = require('path');
var ExtractTextPlugin = require("extract-text-webpack-plugin");
module.exports = {
entry: {
app: './source/app.js',
vendor: './source/vendor.js'
},
output: {
path: path.resolve(__dirname, './.tmp/dist'),
filename: '[name].[chunkhash].js'
},
module: {
rules: [{
test: /.css/,
use:[ ExtractTextPlugin.extract({
loader: ["css-loader"],
})],
}],
},
plugins: [
new ExtractTextPlugin({
filename: "[name].[chunkhash].css",
allChunks: true,
})
]
};
在vendor.js
文件中,我有以下代码:
require("./asdf.css")
在asdf.css
代码中,我只是
body {
background: yellow;
}
这是一个非常简单的设置,但是在运行 webpack 时出现此错误:
ERROR in ./source/asdf.css
Module build failed: ModuleParseError: Module parse failed: /home/vagrant/dorellang.github.io/source/asdf.css Unexpected token (1:5)
You may need an appropriate loader to handle this file type.
| body {
| background: yellow;
| }

我做错了什么?
您没有加载 css 文件,这就是您收到错误的原因。尝试将规则替换为您的webpack.congif.js
,如下所示:
var path = require('path');
var webpack = require('webpack');
module.exports = {
... ... ...
module: {
loaders: [
{
test: /.js$/,
loaders: ['babel'],
include: path.join(__dirname, 'ur path here')
},
{
test: /.css$/,
include: path.join(__dirname, 'ur path here'),
loader: 'style-loader!css-loader'
}
]
}
};
尽管 Webpack 2.2.0 中的"use"应该取代(并且与 "loader" 相同),但情况似乎并非如此。
您似乎还不能在ExtractTextPlugin中使用"use"。此外,您似乎不能为"加载器"使用数组值(代替"use")。
如果替换这段代码:
use:[ ExtractTextPlugin.extract({
loader: ["css-loader"],
})],
有了这个:
loader: ExtractTextPlugin.extract({
loader: ["css-loader"],
}),
..它应该有效。(该替换适用于我类似的损坏测试用例。
看起来主要相关问题是 https://github.com/webpack/extract-text-webpack-plugin/issues/265
