Describe issue

I'm using pipx in my GitHub Actions workflows but it doesn't work in act because /root/.local/.bin isn't on the PATH

And here is the fix that actually makes the executables installed by pipx available:

- name: Add pipx to PATH
  if: github.actor == 'nektos/act'
  run: echo "/root/.local/bin" >> ${GITHUB_PATH}
