Error: Cannot find module 'postcss'

[joebudi]

I followed your instructions in the readme step by step, but I am getting the following error, when I run the following command: hugo server -s exampleSite --themesDir=../.. --disableFastRender

Error: Error building site: POSTCSS: failed to transform "css/styles.css" (text/css): internal/modules/cjs/loader.js:969 throw err; ^

I have installed the prerequisites.

I managed to work around it by moving my config and content folders to root, and simply running hugo serve. I am not sure if this is a workaround or a flawed sense of progress, but I am getting no errors and the site is available.

Weird, as it works on my machine™.
