cleancss -O2 --skip-rebase -o

I'm getting the following error trying to minify CSS and can't find any info on fixing it.

cleancss -O2 --skip-rebase -o /path/to/file/style.css
error: unknown option '--skip-rebase'

Here's a small fix to get minify working:

npm uninstall -g clean-css-cli
npm install -g clean-css@3.4.24

After installing an older version I was able to use the context menu for minifying.

Definitely not ideal, but it works.

yes, that worked for me as well. Thank you

Same here. Kind of a pain.

// “cssminifier”: “clean-css”,
to this line:
“cssminifier”: “uglifycss”,

worked for me only
"cssminifier": "yui",
but need to install java
