Local package.json exists, but node_modules missing, did you mean to install?

Question

Problem :

I am trying to start the Redux application I just cloned from the GitHub repository.

I tried to run it with the below command

npm start

But I am getting below error

> react-redux@1.0.0 start /home/workspace/assignment
> webpack-dev-server --config ./configs/webpack/webpack.config.development.js
sh: 1: webpack-dev-server: not found
npm ERR! file sh
npm ERR! code ELIFECYCLE

npm ERR! react-redux@1.0.0 start: `webpack-dev-server --config ./configs/webpack/webpack.config.development.js`
npm ERR! spawn ENOENT

npm ERR! Failed at the react-redux@1.0.0 start script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
npm WARN Local package.json exists, but node_modules missing, did you mean to install?

How can I fix the above error?

Answer 1

npm start runs the script that the app maker built for easy starting of a app npm install will install all of the packages in your package.json

So you need to run npm install first

After that run npm start

OR

This issue can also come up when you change the system password but not a same updated on the .npmrc file that exist on following path C:\Users\user_name, so please update your password there also..

Please check on it and also run npm install first and then npm start.
