如何解决无法加载通过 ember-auto-import 导入 css 的模块
我正在尝试构建一个 ember 3.25 应用程序，该应用程序通过 CkEditor
ember-auto-import
通过将以下内容添加到我的 package.json 中，我能够使编辑器正常工作：
"@ckeditor/ckeditor5-build-classic": "^27.0.0",并将以下内容添加到我的 ember 组件中：
import ClassicEditor from '@ckeditor/ckeditor5-build-classic';
...
didInsertElement() {
var editor = ClassicEditor
.create( document.querySelector( '#editor' ),{
...
});
}
但是当我尝试通过以下方式添加 ImageResize 模块时：
"@ckeditor/ckeditor5-image": "^27.0.0",在我的组件 (as instructed here) 中：
import Image from '@ckeditor/ckeditor5-image/src/image';
import ImageResize from '@ckeditor/ckeditor5-image/src/image-resize';
我最初看到的错误是：'UnhandledPromiseRejectionWarning: Error: webpack returned errors to ember-auto-import 所以我运行了 AUTO_IMPORT_VERBOSE=true ember serve
我现在看到 ckeditor 不能 @import 嵌套 .css 的错误：
ERROR in ./node_modules/@ckeditor/ckeditor5-ui/theme/components/toolbar/toolbar.css 6:0
Module parse failed: Unexpected character '@' (6:0)

> @import "../../mixins/_unselectable.css";
或者使用 ES6 语法：

Module parse failed: Unexpected token (6:0)

以及尝试包含 svg 文件的错误：
ERROR in ./node_modules/@ckeditor/ckeditor5-widget/theme/icons/drag-handle.svg 1:0
Module parse failed: Unexpected token (1:0)
You may need an appropriate loader to handle this file type,currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders

基于此消息：

似乎我需要向 ember 添加一些 webpack 加载器，但我真的不知道该怎么做。有人可以帮忙吗？
解决方法
@ckeditor/ckeditor5-image/src/image imports a CSS file。由于 CKEditor 使用 CSS-in-JS 和其他不属于 ECMAScript 规范的功能，您需要配置 webpack 以支持它。 CKEditor 的文档包括 minimal configuration example:
const CKEditorWebpackPlugin = require("@ckeditor/ckeditor5-dev-webpack-plugin");
const { styles } = require("@ckeditor/ckeditor5-dev-utils");
module.exports = {
plugins: [
// ...
new CKEditorWebpackPlugin({
// See https://ckeditor.com/docs/ckeditor5/latest/features/ui-language.html
language: "pl",}),],module: {
rules: [
{
test: /ckeditor5-[^/\\]+[/\\]theme[/\\]icons[/\\][^/\\]+\.svg$/,use: ["raw-loader"],},{
test: /ckeditor5-[^/\\]+[/\\]theme[/\\].+\.css$/,use: [
{
loader: "style-loader",options: {
injectType: "singletonStyleTag",attributes: {
"data-cke": true,{
loader: "postcss-loader",options: styles.getPostCssConfig({
themeImporter: {
themePath: require.resolve("@ckeditor/ckeditor5-theme-lark"),minify: true,};
Ember Auto Import 允许您提供自定义 webpack 配置作为 autoImport.webpack 配置键：
// ember-cli-build.js
let app = new EmberApp(defaults,{
autoImport: {
webpack: {
// extra webpack configuration goes here
},});
请联系Ember Auto Import's documentation了解详情。
将两者放在一起，像这样应该工作：
// ember-cli-build.js
const CKEditorWebpackPlugin = require('@ckeditor/ckeditor5-dev-webpack-plugin');
const { styles } = require('@ckeditor/ckeditor5-dev-utils');
let app = new EmberApp(defaults,{
autoImport: {
webpack: {
plugins: [
new CKEditorWebpackPlugin({
// See https://ckeditor.com/docs/ckeditor5/latest/features/ui-language.html
language: "pl",module: {
rules: [
{
test: /ckeditor5-[^/\\]+[/\\]theme[/\\]icons[/\\][^/\\]+\.svg$/,{
test: /ckeditor5-[^/\\]+[/\\]theme[/\\].+\.css$/,use: [
{
loader: "style-loader",options: {
injectType: "singletonStyleTag",attributes: {
"data-cke": true,{
loader: "postcss-loader",options: styles.getPostCssConfig({
themeImporter: {
themePath: require.resolve(
"@ckeditor/ckeditor5-theme-lark"
),});
更新
这个解决方案几乎有效，但有几点需要注意：
从'@ckeditor/ckeditor5-image/src/image-resize'导入ImageResize； '@ckeditor/ckeditor5-build-classic' 中的 ClassicEditor 不起作用！显然这会导致重复模块错误。
因此，在执行此操作之后，按照有关如何 build from source 的说明进行操作，我发现 ckeditor 样式没有在 ember 中加载，直到我按照 extracting CSS 上的说明进行操作，然后一切正常！
>以下是我的 package.json 中的相关部分：
"@ckeditor/ckeditor5-adapter-ckfinder": "^27.0.0","@ckeditor/ckeditor5-autoformat": "^27.0.0","@ckeditor/ckeditor5-basic-styles": "^27.0.0","@ckeditor/ckeditor5-block-quote": "^27.0.0","@ckeditor/ckeditor5-ckfinder": "^27.0.0","@ckeditor/ckeditor5-cloud-services": "^27.0.0","@ckeditor/ckeditor5-core": "^27.0.0","@ckeditor/ckeditor5-dev-utils": "^24.0.0","@ckeditor/ckeditor5-dev-webpack-plugin": "^24.4.2","@ckeditor/ckeditor5-easy-image": "^27.0.0","@ckeditor/ckeditor5-editor-classic": "^27.0.0","@ckeditor/ckeditor5-essentials": "^27.0.0","@ckeditor/ckeditor5-heading": "^27.0.0","@ckeditor/ckeditor5-image": "^27.0.0","@ckeditor/ckeditor5-indent": "^27.0.0","@ckeditor/ckeditor5-link": "^27.0.0","@ckeditor/ckeditor5-list": "^27.0.0","@ckeditor/ckeditor5-media-embed": "^27.0.0","@ckeditor/ckeditor5-paragraph": "^27.0.0","@ckeditor/ckeditor5-paste-from-office": "^27.0.0","@ckeditor/ckeditor5-table": "^27.0.0","@ckeditor/ckeditor5-theme-lark": "^27.0.0","@ckeditor/ckeditor5-typing": "^27.0.0","css-loader": "^5.2.2","mini-css-extract-plugin": "^1.5.0","postcss-loader": "^3.0.0","raw-loader": "^3.1.0","style-loader": "^2.0.0"
还有我的 ember-cli-build.js 文件：
const CKEditorWebpackPlugin = require("@ckeditor/ckeditor5-dev-webpack-plugin");
const { styles } = require("@ckeditor/ckeditor5-dev-utils");
const MiniCssExtractPlugin = require( 'mini-css-extract-plugin' );
module.exports = function (defaults) {
let app = new EmberApp(defaults,{
cssModules: {
includeExtensionInModulePath: true,sassOptions: {
inputFiles: [
'/app/styles/app.scss',includePaths: ['app','app/components']
},// Add options here
autoImport: {
webpack: {
plugins: [
new CKEditorWebpackPlugin({
// See https://ckeditor.com/docs/ckeditor5/latest/features/ui-language.html
// language: "en",new MiniCssExtractPlugin( {
filename: 'ckeditor.css'
} )
],module: {
rules: [
{
test: /ckeditor5-[^/\\]+[/\\]theme[/\\]icons[/\\][^/\\]+\.svg$/,{
test: /ckeditor5-[^/\\]+[/\\]theme[/\\].+\.css$/,use: [
MiniCssExtractPlugin.loader,'css-loader',{
loader: "postcss-loader",options: styles.getPostCssConfig({
themeImporter: {
themePath: require.resolve(
"@ckeditor/ckeditor5-theme-lark"
),});
return app.toTree();
};
还有我的 ck-editor.js 文件（与我的组件保存在同一目录中）：
import ClassicEditorBase from '@ckeditor/ckeditor5-editor-classic/src/classiceditor';
import EssentialsPlugin from '@ckeditor/ckeditor5-essentials/src/essentials';
import UploadAdapterPlugin from '@ckeditor/ckeditor5-adapter-ckfinder/src/uploadadapter';
import AutoformatPlugin from '@ckeditor/ckeditor5-autoformat/src/autoformat';
import BoldPlugin from '@ckeditor/ckeditor5-basic-styles/src/bold';
import ItalicPlugin from '@ckeditor/ckeditor5-basic-styles/src/italic';
import BlockQuotePlugin from '@ckeditor/ckeditor5-block-quote/src/blockquote';
// import EasyImagePlugin from '@ckeditor/ckeditor5-easy-image/src/easyimage';
import HeadingPlugin from '@ckeditor/ckeditor5-heading/src/heading';
import ImagePlugin from '@ckeditor/ckeditor5-image/src/image';
import ImageCaptionPlugin from '@ckeditor/ckeditor5-image/src/imagecaption';
import ImageStylePlugin from '@ckeditor/ckeditor5-image/src/imagestyle';
import ImageToolbarPlugin from '@ckeditor/ckeditor5-image/src/imagetoolbar';
import ImageUploadPlugin from '@ckeditor/ckeditor5-image/src/imageupload';
import LinkPlugin from '@ckeditor/ckeditor5-link/src/link';
import ListPlugin from '@ckeditor/ckeditor5-list/src/list';
import ParagraphPlugin from '@ckeditor/ckeditor5-paragraph/src/paragraph';
import ImageResize from '@ckeditor/ckeditor5-image/src/imageresize';
export default class ClassicEditor extends ClassicEditorBase {}
ClassicEditor.builtinPlugins = [
EssentialsPlugin,UploadAdapterPlugin,AutoformatPlugin,BoldPlugin,ItalicPlugin,BlockQuotePlugin,// EasyImagePlugin,HeadingPlugin,ImagePlugin,ImageCaptionPlugin,ImageStylePlugin,ImageToolbarPlugin,ImageUploadPlugin,ImageResize,LinkPlugin,ListPlugin,ParagraphPlugin
];
ClassicEditor.defaultConfig = {
toolbar: {
items: [
'heading','|','bold','italic','link','bulletedList','numberedList','uploadImage','blockQuote','undo','redo'
]
},image: {
toolbar: [
'imageStyle:full','imageStyle:side','imageTextAlternative'
]
},language: 'en'
};
现在，从我的组件中，我可以调用：
import ClassicEditor from './ck-editor';
...
didInsertElement() {
var editor = ClassicEditor
.create( document.querySelector( '#editor' ),{
...
});
}
