'yo office' not responding after a long time

I am following the instructions here https://dev.office.com/getting-started/addins#selectapp to make my first MS office powerpoint addin.

I installed the yeoman generator and ran this command yo office

yo office                                                                                                                                    ⏎

It stuck at the last line for a very long time (up to 15 minutes now).

How can I resolve this problem? Is there any log file I can inspect to find out the issue?

I just tested the generator on a different machine than my own. It ran successfully inreal 1m18.625s with user 0m33.462s interaction time. Looking at where it stopped for you, the next thing yo office would do is to connect to different git remote origins and install the submodules that are required. I'd suggest quit and run yo office again. :)

If you are interested in debug and contribute to the generator, you can pass Node.js debug flags by running it like this:

# OS X / Linux
node --debug `which yo` <generator> [arguments]

# Windows
# Find the path to the yo binary in Command Prompt
where yo
# Or find the path to the yo binary in PowerShell
get-command yo
# Would be something like C:\Users\<USER>\AppData\Roaming\npm\yo
# Use this path to derive yo cli.js file
# C:\Users\<USER>\AppData\Roaming\npm\node_modules\yo\lib\cli.js
node --debug <path to yo cli.js> <generator> [arguments]
