I'm trying to run CLI happygrep on my Mac OS X 10.9. but an error occured: happygrep - dyld: Library not loaded: /usr/local/opt/ncurses/lib/libncursesw.5.dylib.

I install it like this: 

  $ brew cask update
  $ brew cask install happygrep

Can someone help me ? thanks.

Reinstalling ncurses package should help, e.g.

brew reinstall ncurses

After struggled, I find a way to solve it:

  1. Why error: because CLI happygrep need ncursesw-related lib to support.

  2. Install ncursesw-related lib:

    $ brew search ncurses
homebrew/dupes/ncurses 
$ brew install homebrew/dupes/ncurses

  3. After that, run CLI happygrep 'key-word'.

    See this -happygrep usage.

  • `brew install homebrew/dupes/ncurses` yields the following message `Error: homebrew/dupes was deprecated. This tap is now empty as all its formulae were migrated.`, so it's no longer actual. – bonbonez Jul 30 '19 at 08:51
