[Thilinam93]

Please help me to slove this

[ematipico]

Could you please give us more information and/or a repo to reproduce the issue?

[Thilinam93]

this is my webpack.config.js

var webpack = require('webpack')
var path= require('path')

module.exports = {

    entry:{
        app:'./src/app.js'

    },
    output:{
        filename:'public/build/bundle.js',
        sourceMapFilname:'public/build/bundle.map'

    },
    devtool:'#source-map',
    module:{
        loaders: [{
            test: /\.jsx?$/,
            exclude: /(node_modules)/,
            loader:'babel',
            query:{
               presets:['react','es2015'] 
            }
            }
        ]
    }


}

Package.json

}

That error comming when build this using 'webpack' command

[evenstensberg]

sourceMapFilname:'public/build/bundle.map' and could you try to set devtool to eval ? Also, what's the start command/symlink pointing to? Never seen that before

[Thilinam93]

Issue is fixed, I just uninstall webpack using npm 'uninstall webpack --save-dev' and reinstall webpack using npm install [email protected] --save-dev

Thanks for all

[NASLYGOR96]

help me please

[evenstensberg]

@NASLYGOR96 ´__dirname´ with two underscores in your config file line 7, you only have one
