无法解析文件或目录Webpack

Question

I am getting continuous error from webpack. I am pretty new to this. But I have no clue whatsoever why is it no finding the main.js file which is inside src while running webpack command.

Here is my webpack.config.js

var path = require('path');
var config = {
    entry: {
        main: [
            './src/main.js '
        ]
    },
    output: {
        filename: './public/[name].js'
    },
    module: {
        loaders: [{
            test: /\.jsx?$/, // A regexp to test the require path. accepts either js or jsx,
            exclude: /node_modules/,
            loader: 'babel-loader', // The module to load. "babel" is short for "babel-loader"
            query: {
                presets: ['react', 'es2015']
            }
        }]
    },
    resolve: {
        extensions: ['', '.js', '.jsx']
    }
};

module.exports = config;

Here is my package.json

{
  "name": "react-quickstart",
  "version": "1.0.0",
  "description": "",
  "main": "webpack.config.js",
  "dependencies": {
    "react": "^0.14.7",

    "babel-loader": "^6.2.2",
    "babel-preset-es2015": "^6.5.0",

    "path": "^0.12.7",
    "webpack": "^1.12.13",
    "webpack-dev-server": "^1.14.1"

    "dev": "webpack-dev-server --watch-poll --inline --devtool eval --progress --colors --hot --content-base ./"
  },

I know this is a duplicate issue of Webpack Error . But this issue is unresolved as of now .

I am unable to find the issue here as the package.json seems to be valid and there are no missing commas or anything which I seem to have made mistake.

Answer 1

This can be because of multiple reasons. The best way to identify the exact issue is to tryout the below two commands if you are running webpack 1/2 alone then use the snippet:

webpack --display-error-details

if you are running the webpack dev server then use the snippet:

webpack-dev-server --display-error-details

this would provide a detailed error report in the console

Also if you are providing any additional space in the entry file name that could also be a problem
