Have you done anything to install ack? Or did you just check out the repository? You need to build and install ack before you can use it.

The instructions for installing ack are in the README.md file.

from ack2.

I used the fellow command to build this ack2, but still error..

ack requires Perl 5.8.8 or higher. Perl 5.8.8 was released January 2006.

Required

perl Makefile.PL
make
make test
sudo make install # for a system-wide installation (recommended)

I used the mac OS High Sierra 10.13.4...

You need to install File::Next before you can install ack. Alternatively, you can download the single-file download of ack at https://beyondgrep.com/install/

I am also getting this issue, ack and File::Next are both installed

@djangohunt This repo is for ack 2 that is no longer supported. Are you using ack 2 or 3? If 2, please try with 3. If that doesn't work, please open a new ticket over at https://github.com/beyondgrep/ack3 and give details of what you've done and your install process etc.

Thanks.
