I'm running git-bash on windows. I feel the issue I'm facing is more of a NIX geared question than windows. I have a shell script:

### build.sh

```
myProject="../myProject/"
build="gulp build"

cd "${myProject}"
pwd
"${build}"

```

When I run this script I get error

> 
> gulp build: command not found
> 
> 
> 

When I run "gulp build" directly in the shell, running these same commands by hand then everything works. I tried executing the script via:

`. build.sh` and just `build.sh`

Same error either way. How can I run a script that can access gulp/npm? Why does this fail even when I am sourcing the script?
