error during build process in package.json - css

Question

In the build process, i am trying to run all of them using the npm run build:css command. However, i get an error as shown below. i have performed npm cache clean --force but that doesn't seem to fix the problem.
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! trillo#1.0.0 prefix:css: `postcss --use autoprefixer -b 'last 10 versions' css/style.compile.css -o css/style.prefix.css`
npm ERR! Exit status 1
npm ERR!

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

Answer 1

The postcss command in your prefix:css script seems to be failing. Make sure the command and the arguments are correct.
