Cannot find module 'autoprefixer'

Trying to build docsy locally with hugo and cannot get past this step:

Please have a look at this section in the docsy user guide:

What it comes down to: from the root folder of your project, run:

npm install -D autoprefixer
npm install -D postcss-cli
npm install -D postcss

Afterwards, you should get:

$ npm list
[email protected] your\path\to\yoursite
├── [email protected]
├── [email protected]
└── [email protected]

Does this fix your problem?

thanks @deining -- I've got those in my package.json in the root of the project and have tried installing these as devDependencies, dependencies, and as global dependencies (with the -g flag when installing). All of these result in the same error above.

one thing I'm looking into is the fact that I've cloned the site into a folder in my project -- perhaps there are some hard-coded paths in the build process that expect the hugo site to be at the root of the project

Might be useful to have a look at the Docsy user guide in this repo to compare settings? It's not at the project root.

It seems like you might need to upgrade your version of Node. For details see, Install/Upgrade Node.js. Can you give that a try and let us know if that resolved the issue for you?

Actually, I'm quite sure that this is a dup of #464 so I'll close this for now, if you still have the problem add a comment here and I'll reopen the issue.
