我正在尝试更新我的webpack构建以利用postcss和postcss-loader。但是我在加载字体,图像等方面遇到了问题。
例如尝试导入字体很棒。
这是我在postcss工作之前的设置:
的CSS:
@import "~font-awesome/css/font-awesome.min.css";
webpack.config:
...
module: {
rules: [{
test: /\.css$/,
use: ExtractTextPlugin.extract({
fallback: 'style-loader',
use: 'css-loader'
})
},{
test: /\.(eot|svg|ttf|woff|woff2)$/,
loader: 'file-loader?name=fonts/[name].[ext]'
},{
test: /\.(png|jpg)$/,
loader: 'file-loader?name=images/[name].[ext]'
},{
test: /\.html$/, loader: 'raw-loader'
}]
}
...
试图转向:
@import 'font-awesome'
webpack w / postcss:
...
module: {
rules: [{
test: /\.css$/,
use: ExtractTextPlugin.extract({
fallback: 'style-loader',
use: [{
loader: 'css-loader',
options: {
importLoaders: 1
}
},{
loader: 'postcss-loader',
options: {
ident: 'postcss',
sourceMap: true,
plugins: [require('postcss-import')()]
}
}]
})
},{
test: /\.(eot|svg|ttf|woff|woff2)$/,
loader: 'file-loader?name=fonts/[name].[ext]'
},{
test: /\.(png|jpg)$/,
loader: 'file-loader?name=images/[name].[ext]'
},{
test: /\.html$/, loader: 'raw-loader'
}]
}
...
然而,当我这样做时,我会收到这样的错误:
> ./style.css中的错误模块构建失败:ModuleNotFoundError:Module 找不到:错误:无法解析' ../ fonts / fontawesome-webfont.eot'在 ' /测试项目/公共'
我也尝试过其他一些库(即bootstrap,leaflet),并遇到了同样的问题。

css-loader
似乎无法解析font-awesome/fonts
目录的相对网址路径。
您的css-loader
选项需要alias,如此。
use: [{
loader: 'css-loader',
options: {
importLoaders: 1,
alias: {
"../fonts": "font-awesome/fonts"
}
}
}
我在一个示例项目中对此进行了测试,似乎编译成功。

如果您还使用使用../fonts
相对路径的项目,则可能需要更具体别名。

此webpack配置为我解决了问题:
const rules = [{
test: /\.css$/,
use: [
'style-loader',
{
loader: 'css-loader',
options: {
importLoaders: 1,
sourceMap: true,
}
},
'resolve-url-loader',
{
loader: 'postcss-loader',
options: {
sourceMap: true,
ident: 'postcss',
plugins: () => [],
}
}
]
}, {
test: /\.(png|woff|woff2|eot|ttf|svg)$/,
loader: 'url-loader?limit=100000',
}]
