watchman.plist permission denied when running a react-native initial project

问题

I'm start using react-native and I followed the tutorials on the website, but when running the example project, it returned some error messages on the terminal:

Looking for JS files in
   /Users/username/Desktop/nativeTest/BookSearch

React packager ready.

I tried to chmod com.github.facebook.watchman.plist but actually there's no such file there. Maybe I should change the path of the file?

Other things I've tried:

brew update
brew upgrade watchman
brew uninstall watchman && brew install --HEAD watchman
Restart and reinit the project

Packages Version (if needed):

node: v5.2.0
watchman: v4.2.0

回答1:

Make sure that /Users/username/Library and /Users/username/Library/LaunchAgents are owned by username and have the correct permissions; here's how mine look:

$ ls -ld ~/Library
drwx------+ 57 wez  users  1938 Nov  6 07:49 /Users/wez/Library
$ ls -ld ~/Library/LaunchAgents
drwxr-xr-x  3 wez  users  102 Dec 11 16:13 /Users/wez/Library/LaunchAgents
$ ls -l ~/Library/LaunchAgents/com.github.facebook.watchman.plist
-rw-r--r--  1 wez  users  1545 Dec 11 16:13 /Users/wez/Library/LaunchAgents/com.github.facebook.watchman.plist

Also make sure that you don't run watchman as root or via sudo.

回答2:

Current user do not have permission on folder /Users/[username]/Library/LaunchAgents.

Use the following command to fix this:

$ sudo chown $(whoami) /Users/$(whoami)/Library/LaunchAgents
