I have installed a GAP computer algebra system into my Macbook Pro.

However, if I type 'gap', it will say in the terminal that:

bash: gap: command not found

How I can fix this?

 /Users/myusername/gap4r8/bin

is the location of the script that I can use to boot GAP (gap.sh).

I would like to start GAP in terminal by just typing gap.

  • Where is this PATH in OS X? – Zzz Jul 22 '17 at 12:08
  • Janos, it still says that command not found. – Zzz Jul 22 '17 at 12:23
  • That does not work in OS X Sierra. – Zzz Jul 22 '17 at 12:33
  • Type "export PATH=$PATH:/User/myusername/gap4r8/bin" This will add the location of your executable to the path and allow you to execute with just the executable name. – Raman Sailopal Jul 22 '17 at 13:30
  • This does not work, because there is no file `gap` in `gap4r8/bin` (but there is `gap.sh`). I usually put into `/usr/local/bin` a symlink called `gap`, which points to `/Users/myusername/gap4r8/bin/gap.sh` (I need to remember to update it if my GAP location changes). To create a symlink, first call `cd /usr/local/bin` to change to that directory, and then `ln -s /Users/myusername/gap4r8/bin/gap.sh gap` (edit path as needed). You may need sudo access for that. – Olexandr Konovalov Jul 28 '17 at 22:02
  • For mathematical questions on GAP on Stackexchange framework, I recommend [the `gap` tag on Mathematics Q&A site](https://math.stackexchange.com/questions/tagged/gap). Technical questions may have a better fate in GAP Support or GAP Forum - please see some guidelines and suggestions at https://math.stackexchange.com/tags/gap/info. – Olexandr Konovalov Jul 28 '17 at 22:06
