postcss-cli command not working

Question

I am trying to use postcss-cli from the commandline. I did the following steps:

cd ~/projects/myProject
sudo npm install --save postcss-cli

and then I am trying the following commands:

postcss --help
node_modules/.bin/postcss --help

But this isn't working for me. I don't even get any error.

Answer 1

In case someone is as stupid enough as me: You also need to install postcss-cli :-)
