Git pre-commit hook failing in GitHub for mac (works on command line)

Question

I've created a very simple pre-commit script:-

#!/usr/bin/env sh

# Run tests
npm test
if [ $? -ne 0 ]; then
  echo "Tests failed. Aborting.."
  exit 1
fi

exit 0

---

When I run git commit at the command line (with failing tests), I get the expected exit 1 with the message Tests failed. Aborting...

However, If I use GitHub for Mac however I get:

.git/hooks/pre-commit: line 5: npm: command not found
Tests failed. Aborting..
 (256)

I'm guessing its down to npm not being available to the execution environment that GitHub for Mac is using, but I've been tearing my hair out trying to work out how to fix this.

Answer 1

Resolved. As globally installed node modules end up under /usr/local/bin I simply needed to add the following at the beginning of my pre-commit:

PATH=$PATH:/usr/local/bin:/usr/local/sbin

i.e. appending both /usr/local/bin and /usr/local/sbin to PATH at the point of execution.
