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

问题

I am following a tutorial for setting up react with webpack and babel but i am getting errors.

I have tried re-installing all modules but it didn't worked. I have also matched my config codes still no luck.

ReactJs@1.0.0 create C:\Users\Gourav Thakur\Desktop\Me Creative\github_codebase\ReactJs webpack

Insufficient number of arguments or no entry found. Alternatively, run 'webpack(-cli) --help' for usage info.

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.

回答1:

webpack@4 default value for entry:

By default its value is ./src/index.js, but you can specify a different (or >multiple entry points) by configuring the entry property in the webpack >configuration.

To add a custom entry point, update your webpack as mentioned below. Moreover, move your webpack config file to the root folder.

entry: path.resolve(__dirname) + '/path/to/your/index.js',

However, in the new version of webpack 4.29.* you don't need a webpack config file anymore, so you use the command below to bundle it

webpack ./app/index.js --output ./dist/app.bundle.js --mode development

回答2:

The webpack.config.js should be in the root directory (ReactJs) and not inside the app folder.
