如何修复Webpack中的“未捕获的TypeError:无法读取未定义的属性'调用'”?

标签: webpack-dev-server

基本上,我正在设置webpack,当我尝试在webpack中以开发模式获取dev-server时,遇到了此错误。

我尝试按照其他说明进行操作,从头开始尝试了两次,但仍然遇到相同的错误。我无法弄清楚我在做什么错。如果有人对此问题有解决方案,我将非常感谢。谢谢。

我遇到的错误:

bundle.js:20 Uncaught TypeError: Cannot read property 'call' of undefined
    at __webpack_require__ (bundle.js:20)
    at eval (index.js:2)
    at Object../src/js/index.js (bundle.js:357)
    at __webpack_require__ (bundle.js:20)
    at eval (webpack:///multi_(:8080/webpack)-dev-server/client?:2:18)
    at Object.0 (bundle.js:368)
    at __webpack_require__ (bundle.js:20)
    at bundle.js:69
    at bundle.js:72

错误说明:

// Execute the module function
/******/        modules[moduleId].call(module.exports, module, module.exports, __webpack_require__);

webpack.config.js:

const path = require('path');

module.exports = {
    entry: './src/js/index.js',
    output: {
        path: path.resolve(__dirname, 'dist'),
        filename: 'js/bundle.js'
    },
    devServer: {
        contentBase: './dist'
    }
};

package.json:

{
    "name": "forkify",
    "version": "1.0.0",
    "description": "forkify project",
    "main": "index.js",
    "scripts": {
        "dev": "webpack --mode development",
        "build": "webpack --mode production",
        "start": "webpack-dev-server --mode development --open"
    },
    "author": "Jonas Schmedtmann",
    "license": "ISC",
    "devDependencies": {
        "webpack": "^4.2.0"
    },
    "dependencies": {
        "webpack-cli": "^2.1.5",
        "webpack-dev-server": "^3.4.1"
    }
}

index.html:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>Document</title>
</head>
<body>
    <script src="js/bundle.js"></script>
</body>
</html>

我希望对此有解决方案。

昨天我遇到了同样的问题,并且在网上进行了很多讨论。很少有人认为这是由于webpack-dev-server中的错误引起的,很少有人认为这是由于不正确的块导入引起的。但是,当我生成单个块文件时,情况并非如此。 对我有用的是完全删除node_modules文件夹并重新进行 npm安装。祝你好运。
