Can't build production package - node.js

Question

NPM version (npm --v): 5.4.2
Gulp version (gulp -v): CLI#1.4.0, Local#3.9.1
JHipster version: 4.6.1
Node version: 6.11.3
I'm unable to build a production package. Running the application completes without issues and the same goes for building a package with 'dev' profile.
For some reason when I run ".\mvnw -Pprod package" on the project's root directory I get this error:
[INFO] [17:15:22] Starting 'inject:vendor'...

I understand what it's telling me, I'm missing the .htaccess file but I never needed it before. I recently moved the project from my main drive to the backup drive and since then I can't generate a production package.
If I create an empty ".htaccess" where gulp needs it I get this other error:

(Sorry for the long logs)
I have tried many things, including the full deletion of the repo and cloning it again. I've also tried clearing NPM's cache as advised in this answer. At this point I don't know what else to try.
Thanks !!

Answer 1

I have solved this problem. Gaël Marziou put me in the right track to investigate conflicting versions of node or gulp.
After testing various versions of node, both local and global I tried disabling gulp tasks one by one, none of them helped me really even though the error messages did change. So I tried messing with gulp versions, and that was the answer.
I solved my problem by changing the following line in my package.json:
"gulp": "^3.9.1",
to this:
"gulp": "3.9.1",
And now everything builds perfectly.
Thank you very much :)
