Watchman.plist permission denied when starting an initiative source project

Question

I am starting to use reaction-native, and I have been following the tutorials on the website, but when I started the sample project, it returned some error messages to the terminal:

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

I tried chmod com.github.facebook.watchman.plist, but in fact there is no such file. Maybe I need to change the file path?

Other things I've tried:

• brew update
• brew upgrade watchman
• brew remove watchman && & brew install --HEAD watchman
• Restart and recreate the project

Package Version (if necessary):

• node: v5.2.0
• watchman: v4.2.0
