我想要开始一个redux项目,以下是提供的package.json文件:
{
"name": "redux-starter",
"version": "1.0.0",
"description": "Redux Starter Project",
"main": "index.js",
"scripts": {
"start": "webpack-dev-server --config ./webpack.config.js",
"test": "jest --watch"
},
"keywords": [],
"author": "Mosh Hamedani",
"license": "ISC",
"devDependencies": {
"@babel/core": "^7.8.7",
"@babel/plugin-transform-runtime": "^7.8.3",
"@babel/preset-env": "^7.8.7",
"@types/jest": "^25.1.3",
"axios-mock-adapter": "^1.17.0",
"babel-jest": "^25.1.0",
"jest": "^25.1.0",

"webpack-cli": "^4.9.2",

},
"dependencies": {
"@reduxjs/toolkit": "^1.2.5",
"axios": "^0.19.2",
"immer": "^5.3.6",
"immutable": "^4.0.0-rc.12",
"lodash": "^4.17.15",
"moment": "^2.24.0",
"redux": "^4.0.5",
"redux-devtools-extension": "^2.13.8",
"reselect": "^4.0.0"
}
}
webpack.config.js
在此处:
const path = require("path");
module.exports = {
entry: "./src/index.js",
output: {
filename: "app.js",
path: path.resolve(__dirname, "dist")
},
devServer: {
contentBase: path.join(__dirname, "dist"),
port: 9000
},
mode: "development",
devtool: "source-map"
};
当我运行这个项目时,我收到了错误提示:
$ npm start
> redux-starter@1.0.0 start
> webpack-dev-server --config ./webpack.config.js
[webpack-cli] Invalid options object. Dev Server has been initialized using an options object that does not match the API schema.
- options has an unknown property 'contentBase'. These properties are valid:
object { allowedHosts?, bonjour?, client?, compress?, devMiddleware?, headers?, historyApiFallback?, host?, hot?, http2?, https?, ipc?, liveReload?, magicHtml?, onAfterSetupMiddleware?, onBeforeSetupMiddleware?, onListening?, open?, port?, proxy?, server?, setupExitSignals?, setupMiddlewares?, static?, watchFiles?, webSocketServer? }
这里有什么问题,我该如何解决?谢谢。
