Je reçois une erreur lorsque j'essaie d'importer les éléments suivants dans mon composant de réaction:

J'utilise ce module: https://fonticonpicker.github.io/react-fonticonpicker/
Je reçois cette erreur:

Utilisez npm install

Mon webpack ressemble à ceci:
/**
* 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.
*
* TODO: Instructions.

En fait, je suis tellement surpris que vous ayez utilisé SCSS
webpack config à côté de PostCSS
car avec une petite configuration , vous pouvez prétraiter votre CSS
es et ensuite le traiter en version compressée à l'aide de la syntaxe SCSS. Je vous ai mis une configuration dans ce lien . Je sais que ce n'est pas votre problème principal mais je pense que la configuration de votre projet n'est pas optimisée.
Le lien ci-dessus de Webpack Config vous aidera à améliorer votre configuration et vous pourrez voir les configurations de polices Webpack. en tous cas...
Pour votre erreur exacte, vous devriez corriger votre configuration de police sur Webpack comme ci-dessous:
{
test: /\.(woff|woff2|eot|ttf|svg)$/,
exclude: /node_modules/,
loader: 'file-loader',
options: {
limit: 1024,
name: '[name].[ext]',
publicPath: 'dist/assets/',
outputPath: 'dist/assets/'
}
},
Update après le travail sur le repo } _:
J'écris le fichier webpack.config.dev.js
comme ci-dessous:
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 = {

externals: externals,
};
Et installez également css-loader
et file-loader
.
npm install file-loader css-loader
Indice: il semble que les polices doivent avoir une outputPath
dans la configuration du webpack.
Le problème est que Webpack ne charge pas vos polices @font-face
dans node_modules
. Vous excluez le chargement de CSS à partir de node_modules
. Mais votre @fonticonpicker/react-fonticonpicker/dist/fonticonpicker.base-theme.react.css
est dans node_modules
.
Changer cet extrait dans la configuration de votre webpack
{
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 ),
},
à
{
test: /style\.s?css$/,
use: blocksCSSPlugin.extract( extractConfig ),
},
{
test: /editor\.s?css$/,
use: editBlocksCSSPlugin.extract( extractConfig ),
},
{ test: /(\.css$)/, // you need to load all css imported from node_modules
loaders: ['style-loader', 'css-loader', 'postcss-loader']
}
On dirait que vous manquez css-loader
pour .css
stocké dans node_modules
. C’est pourquoi vous êtes confronté à ce problème . Exécutez npm i -D css-loader
et ajoutez cette règle à votre fichier node_modules > cgb-scrips > config > webpack.config.<env>.js
:
module: {
rules: [
// ...
{
test: /\.css$/,
use: [
{ loader: 'raw-loader' },
{ loader: 'css-loader' },
]
},
// ...
],
},
Alternativement, pour ignorer l'édition webpack.config.js
, vous pouvez simplement importer vos fichiers de la manière suivante:
import 'raw-loader!css-loader!@fonticonpicker/react-fonticonpicker/dist/fonticonpicker.base-theme.react.css';
import 'raw-loader!css-loader!@fonticonpicker/react-fonticonpicker/dist/fonticonpicker.material-theme.react.css';
Votre configuration de chargeur dans Webpack ne correspond pas au fichier CSS Route.
import '@fonticonpicker/react-fonticonpicker/dist/fonticonpicker.base-theme.react.css';
Ce n'est ni style.css
ni editor.css
. Par conséquent, vous obtenez une erreur. De plus, vous ignorez node_modules dans la configuration de votre chargeur de packs Web, mais vous importez le css à partir de node_modules.
Ajouter
{
test: /react\.s?css$/,
use: [{
loader: 'css-loader',
options: {
modules: true
}
}],
},
devrait marcher
