When I try to run this with npm script:

"postcss --use autoprefixer -b 'last 10 versions' input.css -o output.css"

System Environment:

System: Win7 64
Node: v8.11.1
NPM: 5.6.0
"autoprefixer": "^8.4.1",
"postcss-cli": "^5.0.0"

postcss-cli doesn't have an option -b; you'll want to either use a config file, or keep your browserslist config in your package.json

For those of you still having this problem and are using windows, try this link as it worked for me.
Answer. Basically, instead of using single quotes, use double quotes around the "last 10 versions" and escape the quotes.
