Watchman crawl failed. Retrying once with node crawler

问题:

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

回答1:

You're running watchman as root but the state dir, which may contain trigger definitions and thus allow spawning arbitrary commands, is not owned by root. This is a security issue and thus watchman is refusing to start.

The safest way to resolve this is to remove the state dir by running:

rm -rf /usr/local/var/run/watchman/root-state

I'd recommend that you avoid running tools that wish to use watchman using sudo to avoid this happening again.
