Watchman crawl failed. Retrying once with node crawler

Question

Watchman crawl failed. Retrying once with node crawler. Usually this happens when watchman isn't running. Create an empty .watchmanconfig file in your project's root folder or initialize a git or hg repository in your project.

Error: watchman --no-pretty get-sockname returned with exit code=1, signal=null, stderr= 2018-03-23T11:33:13,360: [0x7fff9755f3c0] the owner of /usr/local/var/run/watchman/root-state is uid 501 and doesn't match your euid 0

Answer 1

As Jodie suggested above I tried the below and it worked well, for the benefit of others mentioning below steps which I tried in my mac to fix this issue

1. First, Kill all the server running and close your terminal.
2. Go to 'System preferences' -> 'Security & Privacy' -> privacy tab
3. Scroll down and click 'Full Disk Access'
4. Make sure you checked on 'Terminal' and 'Watchman'.
5. Now relaunch terminal and simply try running again it works!!
