Fresh install - git extension not working

[MrMoronIV]

I installed it using:

git clone https://github.com/c9/core.git c9sdk
cd c9sdk/
scripts/install-sdk.sh

and then

Exiting after uncaught exception in 'spawn':
 Error: spawn git ENOENT
    at exports._errnoException (util.js:1012:11)
    at Process.ChildProcess._handle.onexit (internal/child_process.js:182:32)
    at onErrorNT (internal/child_process.js:348:16)
    at _combinedTickCallback (internal/process/next_tick.js:74:11)
    at process._tickDomainCallback (internal/process/next_tick.js:122:9)

Git is working fine on my CentOS 7 server...

git --version
git version 2.16.5
