Unison command not found

Question

Recently my Unison application has stopped working on my Mac terminal saying the command cannot be found. Not sure if this was the reason but I recently reinstalled brew (which is how it was installed), which may have broken it.

Here is the error output:

mac:~ Imran$ unison sites
-bash: unison: command not found

I can see that if I locate unison unison is found in the following directories:

> /Users/Imran/unison.log /Users/Imran/unison.tar.gz
> /usr/local/Cellar/unison /usr/local/Cellar/unison/2.40.102
> /usr/local/Cellar/unison/2.40.102/COPYING
> /usr/local/Cellar/unison/2.40.102/INSTALL_RECEIPT.json
> /usr/local/Cellar/unison/2.40.102/NEWS
> /usr/local/Cellar/unison/2.40.102/README
> /usr/local/Cellar/unison/2.40.102/TODO.txt
> /usr/local/Cellar/unison/2.40.102/bin
> /usr/local/Cellar/unison/2.40.102/bin/unison
> /usr/local/Library/Formula/unison.rb
> /usr/local/Library/LinkedKegs/unison /usr/local/bin/unison
> /usr/local/opt/unison /usr/share/zsh/5.3/functions/_unison

Can someone help me get this working again? I suspect its something to do with the link to the app being broken.

Answer 1

I had the same issue when trying to use Unison from Windows to Mac (where it has been installed with Brew).

You can give an explicit path for the unison executable on the server by using the command-line option

-servercmd /full/path/name/of/unison

or adding

servercmd=/full/path/name/of/unison

to your profile
