raspberry-wifi-conf: Stuck at $sudo npm start, dhcp server fail? Raspberry Pi 3 Model B

So I have tried installing this several times but I am getting stuck at the last step. I freshly installed the newest version of raspbian stretch and I follow the installation steps but when I get to $sudo npm start my terminal says this

pi@raspberrypi:~/raspberry-wifi-conf $ sudo npm start
 
> raspberry-wifi-conf@0.0.1 start /home/pi/raspberry-wifi-conf
> node server.js
 
 
Wifi is not enabled, Enabling AP for self-configure
 
Force reconfigure enabled - reset AP
... dhcp server failed! -
ifdown wlan0 successful...
ifup wlan0 successful...
... hostapd restarted!
... AP Enable Success!
 
HTTP server running...

Why is this happening? I would post my full terminal but I thought it was too long so if you need to see my full terminal with how everything installed it can be found here https://pastebin.com/BZNDsfhn .

Now since it gets stuck at that command I am forced to restart my terminal since I cant type anymore and if I re-enter the command $sudo npm start I get this

pi@raspberrypi:~ $ cd raspberry-wifi-conf
pi@raspberrypi:~/raspberry-wifi-conf $ sudo npm start
 
> raspberry-wifi-conf@0.0.1 start /home/pi/raspberry-wifi-conf
> node server.js
 
 
Wifi is not enabled, Enabling AP for self-configure
 
Force reconfigure enabled - reset AP
... dhcp server restarted!
ifdown wlan0 successful...
ifup wlan0 successful...
... hostapd restarted!
... AP Enable Success!
 
HTTP server running...

I assume that is probably happening because the first start did not work but maybe it has some information in it that can help you determine the issue. Looking at the first code I posted at the top could it be something to do with my dhcp server failing? How do I fix this? Thank you for any help!!
