尝试在我的react组件中导入以下内容时出现错误：
import FontIconPicker from '@fonticonpicker/react-fonticonpicker';
import '@fonticonpicker/react-fonticonpicker/dist/fonticonpicker.base-theme.react.css';
我正在使用以下模块：https://fonticonpicker.github.io/react-fonticonpicker/
我收到此错误：
./ node_modules/@fonticonpicker/react-fonticonpicker/dist/fonticonpicker.base-theme.react.css 模块解析失败：意外字符'@'（18：0）您可能需要一个 适当的加载程序来处理此文件类型。 | * | / | @ font-face {font-family：fontIconPicker; src：url（assets / fontIconPicker.ttf） 格式（“ truetype”），网址（资产/fontIconPicker.woff） 格式（“ woff”），网址（资产/fontIconPicker.svg#fontIconPicker） format（“ svg”）; font-weight：400; font-style：normal} [class =“ fipicon-“]，[class ^ = fipicon-] {font-family：fontIconPicker！important; speak：none; font-style .......
该错误可以通过我的代码从github复制：https://github.com/gregbia/my-app
使用npm install和npm start，将显示错误。
我的webpack看起来像这样：
/**
* Webpack Configuration
*
* Working of a Webpack can be very simple or complex. This is an intenally simple
* build configuration.
*
* Webpack basics — If you are new the Webpack here's all you need to know:
* 1. Webpack is a module bundler. It bundles different JS modules together.
* 2. It needs and entry point and an ouput to process file(s) and bundle them.
* 3. By default it only understands common JavaScript but you can make it
* understand other formats by way of adding a Webpack loader.
* 4. In the file below you will find an entry point, an ouput, and a babel-loader
* that tests all .js files excluding the ones in node_modules to process the
* ESNext and make it compatible with older browsers i.e. it converts the
* ESNext (new standards of JavaScript) into old JavaScript through a loader
* by Babel.

实际上，我很惊讶您在SCSS旁边使用了PostCSS webpack配置，因为有了little configuration，您可以预处理CSS，然后发布-通过SCSS语法将它们处理为压缩版本。我在this link中为您设置了一个配置。我知道这不是您的主要问题，但我认为您的项目配置尚未优化。
上面的webpack config链接将帮助您改善配置，并且可以看到字体的webpack config。任何方式...
对于确切的错误，您应该像下面这样在webpack上修复字体配置：
{
test: /\.(woff|woff2|eot|ttf|svg)$/,
exclude: /node_modules/,
loader: 'file-loader',
options: {
limit: 1024,
name: '[name].[ext]',
publicPath: 'dist/assets/',
outputPath: 'dist/assets/'
}
},
更新：
我像下面这样写webpack.config.dev.js文件：
const paths = require('./paths');
const externals = require('./externals');
const autoprefixer = require('autoprefixer');
const ExtractTextPlugin = require('extract-text-webpack-plugin');
// Extract style.css for both editor and frontend styles.
const blocksCSSPlugin = new ExtractTextPlugin({
filename: './dist/blocks.style.build.css',
});
// Extract editor.css for editor styles.
const editBlocksCSSPlugin = new ExtractTextPlugin({
filename: './dist/blocks.editor.build.css',
});
// Configuration for the ExtractTextPlugin — DRY rule.
const extractConfig = {
fallback: 'style-loader',
use: [
// "postcss" loader applies autoprefixer to our CSS.
{loader: 'css-loader'},
{
loader: 'postcss-loader',
options: {
ident: 'postcss',
plugins: [
autoprefixer({
browsers: [
'>1%',
'last 4 versions',
'Firefox ESR',
'not ie < 9', // React doesn't support IE8 anyway
],
flexbox: 'no-2009',
}),
],
},
},
// "sass" loader converts SCSS to CSS.
{
loader: 'sass-loader',
options: {
// Add common CSS file for variables and mixins.
data: '@import "./src/common.scss";\n',
outputStyle: 'nested',
},
},
],
};
// Export configuration.
module.exports = {
entry: {
'./dist/blocks.build': paths.pluginBlocksJs, // 'name' : 'path/file.ext'.
},
output: {
// Add /* filename */ comments to generated require()s in the output.
pathinfo: true,
// The dist folder.
path: paths.pluginDist,
filename: '[name].js', // [name] = './dist/blocks.build' as defined above.
},
// You may want 'eval' instead if you prefer to see the compiled output in DevTools.
devtool: 'cheap-eval-source-map',
module: {
rules: [
{
test: /\.(js|jsx|mjs)$/,
exclude: /(node_modules|bower_components)/,
use: {
loader: 'babel-loader',
options: {
// @remove-on-eject-begin
babelrc: false,
presets: [require.resolve('babel-preset-cgb')],
// @remove-on-eject-end
// This is a feature of `babel-loader` for webpack (not Babel itself).

cacheDirectory: true,
},
},
},
{
test: /style\.s?css$/,
exclude: /(node_modules|bower_components)/,
use: blocksCSSPlugin.extract(extractConfig),
},
{
test: /editor\.s?css$/,
exclude: /(node_modules|bower_components)/,
use: editBlocksCSSPlugin.extract(extractConfig),
},
{
test: /\.css$/,
include: /(node_modules\/@fonticonpicker\/react-fonticonpicker\/dist)/,
loaders: ['style-loader', 'css-loader']
},
{
test: /\.(woff|woff2|eot|ttf|svg)$/,
include: /(node_modules\/@fonticonpicker\/react-fonticonpicker\/dist)/,
loader: 'file-loader',
options: {
limit: 1024,
name: '[name].[ext]',
publicPath: 'dist/assets/',
outputPath: 'dist/assets/'
}
}
],
},
// Add plugins.
plugins: [blocksCSSPlugin, editBlocksCSSPlugin],
stats: 'minimal',
// stats: 'errors-only',
// Add externals.
externals: externals,
};
还要安装css-loader和file-loader。
npm install file-loader css-loader
提示：似乎字体在Webpack配置中必须有outputPath。
答案 1 :(得分：2)
问题是webpack无法在@font-face中加载字体node_modules。您正在从node_modules中排除css的加载。但是您的@fonticonpicker/react-fonticonpicker/dist/fonticonpicker.base-theme.react.css在node_modules中。
在您的webpack配置中更改此代码段
{
test: /style\.s?css$/,
exclude: /(node_modules|bower_components)/,
use: blocksCSSPlugin.extract( extractConfig ),
},
{
test: /editor\.s?css$/,
exclude: /(node_modules|bower_components)/,
use: editBlocksCSSPlugin.extract( extractConfig ),
},
到
{
test: /style\.s?css$/,
use: blocksCSSPlugin.extract( extractConfig ),
},
{
test: /editor\.s?css$/,
use: editBlocksCSSPlugin.extract( extractConfig ),
},
{ test: /(\.css$)/, // you need to load all css imported from node_modules
loaders: ['style-loader', 'css-loader', 'postcss-loader']
}
答案 2 :(得分：1)
您在webpack中的加载程序配置与CSS文件Route不匹配。
new_string //它既不是import '@fonticonpicker/react-fonticonpicker/dist/fonticonpicker.base-theme.react.css';
也不是style.css。因此，您会得到一个错误。另外，您将忽略Webpack加载程序配置中的node_modules，但从node_modules导入css。
添加
editor.css应该工作
答案 3 :(得分：1)
似乎您丢失了css-loader中存储的.css的{{1}}。这就是为什么您要面对此issue。运行node_modules并将此规则添加到您的npm i -D css-loader文件中：
node_modules > cgb-scrips > config > webpack.config.<env>.js或者，要跳过编辑module: {
rules: [
// ...
{
test: /\.css$/,
use: [
{ loader: 'raw-loader' },
{ loader: 'css-loader' },
]
},
// ...
],
},
，您可以像这样简单地导入文件：
webpack.config.js
