Processing stops after "Finished 'vendorJS' after"

Bug Report

Expected Behavior

(Write what you thought would happen.)
I expected WPGulp to complete processing.

Actual Behavior

(Write what happened. Please add screenshots!)
I installed WPGulp according to instructions, including setting projectURL: 'localhost/ltgbase'.

On npm start, processing stopped after the Finished 'vendor.JS' after line. Browsersync is listed as proxying http://localhost rather than http://localhost/ltgbase as specified in wpgulp.config.js. (I tried both localhost/ltgbase and http://localhost/ltgbase.) Local, External, UI, and UI External are not populated.

Steps to Reproduce

(Write your steps here:)

1. Install WPGulp
2. Set projectURL: 'localhost/directory' in the wpgulp.config.js
3. npm start

1. node -v: 10.15.3
2. npm -v: 6.4.1
3. yarn --version (if you use Yarn):

Then, specify:

1. Operating system: Windows 10
2. Browser and version (if relevant):
3. Local install: XAMPP 7.0.30
