Problems creating a CLI tool to distribute on NPM for local installation only

I have created a simple CLI tool what I want users to install and have commands available while the user is cd'd into a project. Let me describe:

1. Inside my cli-tools project, the package defines the following:

   {
      "bin": {
         "foo-script": "./bin/foo-script"
      }
   }
   
   

2. User installs script (directly from github at the moment, it's a private tool):

   npm install git+https://...../cli-tools --save
   
   

3. At this point, if the user types which foo-script, they see:

   node_modules/.bin/foo-script
   
   

   Most user have ./node_modules/.bin as part of their $PATH

4. Upon executing foo-script, the following complain arises:

   /Users/meee/.nvm/versions/node/v6.10.0/bin/pg-util: No such file or directory
   
   

Sooo, how can I get users to install my script using npm, and have the commands listed under "bin" directly available? Thanks?
