Excellent project but I am unable to build using Windows with this command `hugo server`. This is the error shown to me:

```auto
Built in 5358 ms
Error: error building site: POSTCSS: failed to transform "assets/main/bundle.min.css" (text/css): 'C:\Program' is not recognized as an internal or external command,
operable program or batch file.

```

Check the path to your postcss program and make sure you have installed hugo extended

What @chrillek said, and also ensure to follow the installation documentation for your theme if you are using one.

This is a known issue ([#7333](https://github.com/gohugoio/hugo/issues/7333)) on Windows. You can either:

1. Remove the spaces from the project’s path, or
2. Move the postcss setttings into package.json ([see this comment](https://github.com/gohugoio/hugo/issues/7333#issuecomment-1048571703))
