when i input npm run dev,these errors appear.
But my npm and node's version are satisfy condition. npm-4.1.2 node-6.7.0.

[posva]

The issue should be opened in the template reproducing the error and with more information about the system it was run with

[onlyfzz]

I think its a bug,when i cancel the eslint and npm run dev,it remind me i show install the eslint-friendly-formatter,last time i ignore the message so i dont konw what happend,but i think the module show be auto npm rather than manual.

[Smith-Cruise]

@onlyfzz actually,i had resloved it just now.
First,find file build/webpack.base.conf.js.
Then delete var eslintFriendlyFormatter = require('eslint-friendly-formatter').
This problem is caused by canceling eslint,so you just need to delete that line in configuration

[anuj-know]

I have the same issue . and i check for var eslintFriendlyFormatter in build/webpack.base.conf.js . there is no such variable.

thanks

check if port 8080 used by another program,I just resolved this problem by changing port number

@matan-modai i googled "webpack template vuejs" and found it on Github https://github.com/vuejs-templates/webpack. then in Issues section look at this issue "Bug with webpack-dev-server 2.10.0 - Unable to start webpack-dev-server" and there is a solution mentioned.

[nomantufail]

@rgalaxy try running this command first : npm install --save-dev cross-env

[anson-GH]

change the config >index.js port: 8080 to other port eg, port: 8081

[newsapkota]

npm install --save-dev cross-env

Thanks, this save my day, it's works.
