在我的项目中，我正在使用antd react 组件库，我需要使用 ts-loader 以合理的方式加载组件。现在我正在尝试摔跤 webpack 以转译更少的文件，但我收到以下错误：
ERROR in ./node_modules/antd/lib/button/style/index.less
Module build failed: Error: Cannot find module 'less'
at Function.Module._resolveFilename (internal/modules/cjs/loader.js:594:15)
at Function.Module._load (internal/modules/cjs/loader.js:520:25)
...
看起来要么没有安装较少的加载程序(确实如此(，要么配置不正确(应该是(。这是我的 webpack 配置：
webpack.dev.js
module: {
rules: [
{
test: /.scss$/,
loaders: ['style-loader', 'css-loader', 'postcss-loader', 'sass-loader']
},
{
test: /.css$/,
loaders: ['style-loader', 'css-loader']
},
{
test: /.less$/,
loader: 'less-loader' // compiles Less to CSS
},
]
},
Common.webpack.js
const getTsLoaderRule = env => {
const rules = [
{ loader: 'cache-loader' },
{
loader: 'ts-loader',
options: {
transpileOnly: true,
getCustomTransformers: () => ({
before: [ tsImportPluginFactory({
libraryDirectory: 'es',
libraryName: 'antd',
style: 'css',
})]
}),
compilerOptions: {
module: 'es2015'
}
},
}
];
if (env === 'development') {
rules.unshift({
loader: 'react-hot-loader/webpack'
});
}
return rules;
};
...
module: {
rules: [
{
test: /.tsx?$/,
use: getTsLoaderRule(options.env),
include: [utils.root('./src/main/webapp/app')],
exclude: ['node_modules']
},
{
test: /.(jpe?g|png|gif|svg|woff2?|ttf|eot)$/i,
loaders: ['file-loader?hash=sha512&digest=hex&name=content/[hash].[ext]']
},
{
enforce: 'pre',
test: /.jsx?$/,
loader: 'source-map-loader'
},
{
test: /.tsx?$/,
enforce: 'pre',
loaders: 'tslint-loader',
exclude: ['node_modules']
}
]
},
有什么想法吗？
错误消息不是关于配置错误的less-loader，而是缺少less，这是包的对等依赖关系。运行npm i -S less进行安装。
