npm start doesn't detect changes
When you save a file while
npm start is running, the browser should refresh with the updated code.
If this doesn't happen, try one of the following workarounds:
- If your project is in a Dropbox folder, try moving it out.
- If the watcher doesn't see a file called
index.jsand you're referencing it by the folder name, you need to restart the watcher due to a Webpack bug.
- Some editors like Vim and IntelliJ have a "safe write" feature that currently breaks the watcher. You will need to disable it. Follow the instructions in "Working with editors 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.
- On Linux and macOS, you might need to tweak system settings to allow more watchers.
- If the project runs inside a virtual machine such as (a Vagrant provisioned) VirtualBox, create an
.envfile in your project directory if it doesn't exist, and add
CHOKIDAR_USEPOLLING=trueto it. This ensures that the next time you run
npm start, the watcher uses the polling mode, as necessary inside a VM.

npm test hangs on macOS Sierra
If you run
npm test and the console gets stuck after printing
react-scripts test --env=jsdom to the console there might be a problem with your Watchman installation as described in facebookincubator/create-react-app#713.
We recommend deleting
node_modules in your project and running
npm install (or
yarn if you use it) first. If it doesn't help, you can try one of the numerous workarounds mentioned in these issues:
It is reported that installing Watchman 4.7.0 or newer fixes the issue. If you use Homebrew, you can run these commands to update it:
watchman shutdown-server brew update brew reinstall watchman
You can find other installation methods on the Watchman documentation page.
If this still doesn't help, try running
launchctl unload -F ~/Library/LaunchAgents/com.github.facebook.watchman.plist.
There are also reports that uninstalling Watchman fixes the issue. So if nothing else helps, remove it from your system and try again.
npm run build silently fails
It is reported that
npm run build can fail on machines with no swap space, which is common in cloud environments. If the symptoms are matching, consider adding some swap space to the machine you're building on, or build the project locally.
npm run build fails on Heroku
