[英]Could not resolve styleName
我在我的 React 應用程序中使用 scss 模塊,但每次更改styleName
,都會收到錯誤消息:在熱重載期間Could not resolve styleName
。 如果styleName
沒有任何相應的樣式,我也會收到錯誤消息。 我每次都必須重新啟動服務器才能重新編譯。 我的配置有問題嗎?
webpack.dev.js
const webpack = require('webpack')
const BrowserSyncPlugin = require('browser-sync-webpack-plugin')
module.exports = require('./webpack.base')({
mode: 'development',
devServer: {
hot: true,
port: 3000,
historyApiFallback: true
},
plugins: [
new webpack.HotModuleReplacementPlugin(),
new BrowserSyncPlugin(
{ proxy: 'http://localhost:3000/', open: false },
{ reload: false }
)
],
module: {
rules: [
{
test: /\.jsx?$/,
exclude: /node_modules/,
use: {
loader: 'babel-loader',
options: {
plugins: [
[
'react-css-modules',
{
"filetypes": {
".scss": { "syntax": "postcss-scss" }
},
"generateScopedName": '[name]_[local]_[hash:base64:5]'
}
],
],
},
},
resolve: {
extensions: ['.js', '.jsx']
}
},
{
test: /\.(sa|sc)ss$/,
use: [
{ loader: 'style-loader' },
{
loader: 'css-loader',
options: {
modules: true,
sourceMap: false,
localIdentName: '[name]_[local]_[hash:base64:5]'
}
},
{
loader: 'sass-loader'
}
]
},
{
test: /\.css$/,
use: ['style-loader', 'css-loader', 'postcss-loader']
},
]
}
})
例子.scss
.header-container {
font-size: 14px;
}
.release-index {
width: 5%;
}
您是否安裝了postcss-scss
並放置了像這個插件選項這樣的配置?
['react-css-modules', {
filetypes: {
'.scss': {
syntax: 'postcss-scss'
}
}
}
]
您必須安裝postcss-import-sync2並將其作為第一個插件導入,如下所示(配置babel-plugin-react-css-modules )。
也許較新的postcss-import也可以在這里工作,但它沒有同步模式,並且postcss-import-sync2也在README.md中使用
如果您想支持導入 sass 部分 _my-partial.scss 就像 @import './my-partial'; ,則需要自定義解析函數。
const path = require('path');
// Later configuring plugin...
{
filetypes: {
".scss": {
syntax: "postcss-scss",
plugins: [
[
"postcss-import-sync2",
{
resolve: function(id, basedir, importOptions) {
let nextId = id;
if (id.substr(0, 2) === "./") {
nextId = id.replace("./", "");
}
if (nextId[0] !== "_") {
nextId = `_${nextId}`;
}
if (nextId.indexOf(".scss") === -1) {
nextId = `${nextId}.scss`;
}
return path.resolve(basedir, nextId);
}
}
],
[
"postcss-nested",
{
bubble: ["@include"],
preserveEmpty: true
}
]
]
}
},
generateScopedName: "[path]___[name]__[local]___[hash:base64:5]",
webpackHotModuleReloading: true,
exclude: "node_modules",
handleMissingStyleName: "warn"
}
樣式.scss :
@import './example';
