jest-haste-map: Watchman crawl failed. Retrying once with node crawler

I just found an error while running the metro of react native it came after upgrading the os

the error was

    jest-haste-map: 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 error: std::__1::system_error: open: /Users/dongjae/Desktop/wellCupOfficial/wellcupOfficial/wellcupApp: Operation not permitted. Make sure watchman is running for this project. See https://facebook.github.io/watchman/docs/troubleshooting.
/Users/dongjae/Desktop/wellCupOfficial/wellcupOfficial/wellcupApp/node_modules/metro-hermes-compiler/src/emhermesc.js:77
          throw ex;

after googling it and trying some soulutions for 3hours? i found that i had to add "watchman" to Full Disk Access under Security&Privacy

Also I found that watchman is in dir opt/local/bin/watchman However, the biggest problem is that I have found no way to access to this folder I can't even see this folder in the selecting window Please help this poor developer..

I was facing an issue that Watchman was not present in the list to allow for full disk access on Mac m1.

I managed to fix this by

  1. Go to System preferences > Security & Privacy
  2. Select Full Disk Access
  3. click + button to add new
  4. You need to select Macintosh HD from the folders list
  5. Press this combination Shift + Command + . together to view all the directories list
  6. Click opt > homebrew > bin (watchman is installed in this folder for MacOS Catalina)
NOTE: If you do not find it here. open the terminal and run

> which watchman

This should give you the installed path for watchman.
  1. Open watchman and it should show the watchman in the list to select for full disk access.

Once I had watchman selected in the full disk access, I restarted my VSCode and the error was gone.

In the root of your project, run watchman watch-del-all, then run watchman shutdown-server. The next time you run the app you will be prompted to give access to watchman. This should resolve the issue.

On macOS I had to run sudo yarn start it worked and the system showed an alert to give watchman read rights, after accepting yarn start can run normally without sudo.

Try to move outside the Desktop folder. I've moved my projects to my User folder, and everything works.

Strange, yes. But at least at the moment, I can continue coding.
