NodeJS Child Process EXEC Command Failed with NVM Permission denied OSX

I am attempting to launch nvm within a child process in Nodejs on OSX However in doing so, I am getting the following error: /bin/sh: /Users/miker/.nvm/nvm.sh: Permission denied. child process exited with code 126 (I call the explicit path to nvm, since running without it, the child process can't see the executable.)

This is obvious that it is a permission issue. However, I am not sure why since I can launch the commands on there own without issue. It is only when launching in a child process does this fail. Perhaps, the child process runs in the context of another profile? If so, is there a way to maintain the current profile or context?

Here is an example code

let exec = require('child_process').exec;

let child = exec('echo $NVM_DIR && $NVM_DIR/nvm.sh use && npm install', {
    cwd: './build/'
});

child.stdout.on('data',
    (data) => {
        console.log(data);
    });

child.stderr.on('data',
   (data) => {
        //throw errors
        console.log(data);
    });

child.on('close', (code) => {
    console.log('child process exited with code ' + code);
});

If anyone has a solution to this problem, please let me know.
