You will need to disable it. Follow the instructions in [“Working with editors supporting safe write”](https://webpack.github.io/docs/webpack-dev-server.html#working-with-editors-ides-supporting-safe-write). * If your project path contains parentheses, try moving the project to a path without them. This is caused by a [Webpack watcher bug](https://github.com/webpack/watchpack/issues/42). * On Linux and macOS, you might need to [tweak system settings](https://webpack.github.io/docs/troubleshooting.html#not-enough-watchers) to allow more watchers. -* If the project runs inside a virtual machine such as (a Vagrant provisioned) VirtualBox, run `npm install --save-dev cross-env` in its root folder and then replace `"react-scripts start"` in the `scripts` section of its `package.json` with `"cross-env CHOKIDAR_USEPOLLING=true react-scripts start"`. This ensures that the next time you run `npm start`, the watcher uses the polling mode, as necessary inside a VM. +* If the project runs inside a virtual machine such as (a Vagrant provisioned) VirtualBox, create an `.env` file in your project directory if it doesn’t exist, and add `CHOKIDAR_USEPOLLING=true` to it.
