React-native: Watchman was not found in PATH

[junaidahmed93]

Hello everyone,
I am trying to run react-native app since last week but i am unable to run it.
Already created an issue but that has been closed by saying "try to google for it"

I don't know what going wrong with react-native start

Always getting

Watchman was not found in PATH.  See https://facebook.github.io/watchman/docs/install.html for installation instructions
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 was not found in PATH.  See https://facebook.github.io/watchman/docs/install.html for installation instructions
Watchman:  Watchman was not found in PATH.  See https://facebook.github.io/watchman/docs/install.html for installation instructions

    at process._tickCallback (internal/process/next_tick.js:98:9)

I am unable to understand if the process is depended on watchman then why there is no discussion in official document with regards to start process
I haven't found any tutorial that installed watchman before starting.
Not even found the way to install watchman except npm install watchman

Hey @junaidahmed93 and thanks for posting this! @DanielMSchmidt tells me this issue looks like a question that would be best asked on StackOverflow. StackOverflow is amazing for Q&A: it has a reputation system, voting, the ability to mark a question as answered. Because of the reputation system it is likely the community will see and answer your question there. This also helps us use the GitHub bug tracker for bugs only. Will close this as this is really a question that should be asked on SO.

@junaidahmed93 How did you resolve this issue ?

[junaidahmed93]

Just remove watchman
npm uninstall -g watchman
And Never install that again :)

@junaidahmed93 I think you need to install it with homebrew
