Theme Installation Failed - Any Suggestions?

[sukaikan]

Hi, I am interested to learn Hugo with your theme, it surely looks great. But when I am trying to run this it showed the following:

[hugo] ERROR Failed to read Git log: fatal: not a git repository (or any of the parent directories): .git
[tw]
[tw] Rebuilding...
[hugo] Built in 297 ms
[hugo] Error: error building site: POSTCSS: failed to transform "css/style.css" (text/css): 'C:\Program' is not recognized as an internal or external command,
[hugo] operable program or batch file.
[hugo] npm run watch:hugo exited with code 1

I am new to Hugo, which one is wrong? Can you show me suggestions? Thanks

1. What OS are you using right now?
2. What version of Node.js and NPM are you using?

Please provide as much info as possible, if you can.
