# An error has occurred :-(

## Usual error causes

1. You started the application from an IDE and you didn't run `npm start` or `npm run webpack:build`.
2. You had a network error while running `npm install`. If you are behind a corporate proxy, it is likely that this error was caused by your proxy. Have a look at the JHipster error logs, you will probably have the cause of the error.
3. You installed a Node.js version that doesn't work with JHipster: please use an LTS (long-term support) version, as it's the only version we support.

## Building the client side code again

If you want to go fast, run `./mvnw` to build and run everything.

If you want to have more control, so you can debug your issue more easily, you should follow the following steps:

1. Install npm dependencies with the command `npm install`
2. Build the client with the command `npm run webpack:build` or `npm start`
3. Start the server with `./mvnw` or using your IDE
