TypeError: First argument must be a string, Buffer, ArrayBuffer, Array, or array-like object.


Found solution here but had to remove the package-lock.json file before running npm install on the last step.

@erikandershed do you get any errors, did you try the method i told you. 
1) remove the node folder "rm -rf node_modules"
2) reinstall all the packages npm install 
3) goto the gulp-sftp folder inside the node_modules cd node_modules/gulp-sftp
4) open it in a text editor("subl .") and change the ssh2 package version to "~0.5.5"
