[英]Webpack-dev-server Error: Cannot find module , can't understand why?
我有一个新的项目和设置webpack用作模块捆绑器但是当我使用npm启动脚本启动webpack-dev-server 时 ,我收到一个错误
Error can't find module :
at Function.Module._resolveFilename (internal/modules/cjs/loader.js:571:15)
at Function.Module._load (internal/modules/cjs/loader.js:497:25)
at Module.require (internal/modules/cjs/loader.js:626:17)
at require (internal/modules/cjs/helpers.js:20:18)
虽然我写的一切都是正确的,但我不明白为什么会发生这种情况? 谁能告诉我为什么会这样?
这是我的package.json文件
{
"name": "simple-webpack-project",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"start": "webpack-dev-server --config ./webapck.common.js"
},
"keywords": [],
"author": "",
"license": "ISC",
"devDependencies": {
"css-loader": "^1.0.0",
"html-webpack-plugin": "^3.2.0",
"mini-css-extract-plugin": "^0.4.1",
"style-loader": "^0.21.0",
"webpack": "^4.15.1",
"webpack-cli": "^3.0.8",
"webpack-dev-server": "^3.1.4"
}
}
这是我的webpack.common.js
const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin') ;
module.exports = {
entry:{
index:'./src/index.js',
app:'./src/app.js'
},
output: {
path: path.join(__dirname,'dist'),
filename: "[name].js"
},
module: {
rules: [
{
test :/\.css$/,
use:['style-loader','css-loader']
}
]
},
plugins: [
new HtmlWebpackPlugin(
{
chunks:['app'],
template:'./index.html'
}
)
],
devServer: {
port:4000
}
}
我在我的IDE中尝试了你的项目设置,我想我找到了你的问题的解决方案,我认为你在package.json文件中写了错误的配置名称
您在磁盘中的文件名为webpack.common.js
package.json webapck.common.js中的文件名
所以要解决问题
将package.json中的文件名更改为webpack.common.js而不是webapck.common.js这将解决我认为的问题,将package.json 启动脚本更改为
"start": "webpack-dev-server --config ./webpack.common.js"
