Hi,
I had the same problem, I don’t know if you’ve solved it yet but for me it turned out to be some simple mistakes.
I thought I had followed the instructions to the letter, but actually at first I hadn’t cloned the module into the modules folder, just into the mirror folder. After cursing my own stupidity for that I carried on a while but still couldn’t get it working.
I tried the tip for generating a new access token but that wasn’t it. I then realised that when I cloned the module (into the correct folder!) I missed the small but vital step of navigating into the new folder before carrying out npm install.
I don’t know if any of you have made mistakes as daft as mine, but I finally got it working so thought I’d let you know.
Hope it helps someone!
