Error: Cannot find module 'postcss'

rockey5520 commented 4 years ago

Hi dirkolbrich,

Hope you are having a good day

I noticed when using the theme you developed works well in windows env but when I tried this with WSL it fails with below error, would you be able to assist? Error is the same on my project and also the same when I build a new project using your latest repo contents.

you might need to install postcss via e.g. npm install -g postcss

rockey5520 commented 4 years ago

I have installed postcss gloabally and its available in the node_modules folder

dirkolbrich commented 4 years ago

Hi, can you provide a working example repo which reproduces this error?

what system do you use and how is it set up
which Hugo version
which NPM version - what is globally, what is locally installed

npm list -g --depth=1
npm list --depth=1

project structure - do you run this theme repo as a stand alone repo or as a theme within a Hugo project

If you have tree installed, try

tree -L 2

please run the server command in verbose mode

hugo server -s exampleSite --themesDir=../.. -v

Sorry, no help from my side as this seems to be a NPM setup issue.
