javascript - 无法解析 "app.js"- Webpack

Question

问题

所以，我正在使用 Webpack 和 ES6 开发一个网络应用程序。当我尝试运行 Webpack 时，它告诉我它无法解析“app.js”。我已经在互联网上寻找解决方案，但我找不到一个，有人可以帮助我吗？完整错误是:

ERROR in ./assets/js/main.js
Module not found: Error: Can't resolve 'app.js' in 'C:\Users\sidna\Dropbox\Dev Stuff\Web Apps\Mondrian Generator\assets\js'
 @ ./assets/js/main.js 4:0-17

webpack.config.js

module.exports = {
entry: './assets/js/main.js',
output: {
    filename: 'assets/js/build.js',
},
watch: true,
module: {
    loaders: [
        {
            test: /\.scss$/, loader: "style-loader!css-loader!sass-loader"
        },
        {
          test: /\.js$/,
          exclude: /node_modules/,
          use: {
            loader: 'babel-loader',
            options: {
              presets: ['env']
            }
          }
        }
    ],
}
};

app.js(空)

ma​​in.js

// SCRIPTS
require("app.js");

// STYLES
require("../css/large.scss");

当导入既不是绝对路径(以/开头)也不是明确的相对路径(以./或../开头) >)，它被解析为一个模块，这意味着它是 Loading from node_modules Folders .

你的app.js不在node_modules中，所以需要改成相对路径(假设和main.js在同一个目录下) ):

require("./app.js");

Webpack 遵循 Node.js 的导入行为，但它也允许您使用 resolve.modules 更改它。选项。
