Webpack 4:未找到输入模块中的错误:错误:无法解析“./src" [英] Webpack 4 : ERROR in Entry module not found: Error: Can't resolve './src'

问题描述

我第一次尝试运行 webpack-4

webpack ./src/js/app.js ./dist/app.bundle.js

它显示警告/错误:

WARNING in configuration
The 'mode' option has not been set, webpack will fallback to 'production' for this value. Set 'mode' option to 'development' or 'production' to enable defaults for each environment.
You can also set it to 'none' to disable any default behavior. Learn more: https://webpack.js.org/concepts/mode/

ERROR in multi ./src/js/app.js ./dist/app.bundle.js
Module not found: Error: Can't resolve './dist/app.bundle.js' in 'D:\wamp64\www\webpack-4'
 @ multi ./src/js/app.js ./dist/app.bundle.js

然后我尝试改变模式

webpack --mode development

它显示:

ERROR in Entry module not found: Error: Can't resolve './src'

推荐答案

已解决

花了很多时间找出解决方案.

Spent a lot of time to find out the solution.

解决方案:将index.js文件添加到src文件夹中.

Solution: Add index.js file into src folder.

就是这样！...解决了:)

That's it!.. solved :)

在研究期间，我发现了一些关于 webpack 4 的事实:

webpack 4 默认不需要配置文件！

webpack 4不需要定义入口点:它会以 ./src/index.js 作为默认值！

webpack 4 there is no need to define the entry point: it will take ./src/index.js as the default!
