Error Loading PostCSS Plugin failed Cannot find module 'autoprefixer'

[j-p-burdell]

Hello!

I'm new to Docsy and Hugo and am going to be using Docsy as my documentation site. I'm running into an issue when trying to build the Docsy Example site with GitLab CI. I'm able to successfully build the site locally using hugo server and have attempted multiple options for installing Autoprefixer but keep running into this issue:

Error: Error building site: POSTCSS: failed to transform "scss/main.css" (text/css): Error: Loading PostCSS Plugin failed: Cannot find module 'autoprefixer'

I installed Autoprefixer per the Docsy guide and have subsequently tried with -g, cross-env, --save-dev options but to no avail. I have the prerequisites installed (including Autoprefixer) on both the system hosting the GitLab-runner as well as the GitLab system itself.

In terms of GitLab CI, i'm using the .gitlab-ci.yml file from the Docsy site and have configured the "baseURL" accordingly. Also, per a post on the Stackoverflow forum, I also implemented a postcss.config.js script:

module.exports = { plugins: { autoprefixer: { browsers: ['last 10 versions'] } } };

Any assistance would be much appreciated and please let me know if any additional data/information is needed :).

Please find the versions installed below:

• Hugo: hugo v0.111.3-5d4eb5154e1fed125ca8e9b5a0315c4180dab192+extended linux/amd64 BuildDate=2023-03-12T11:40:50Z VendorInfo=gohugoio
• Node: v18.16.0
• PostCSS: 10.1.0
• Autoprefixer: autoprefixer 10.4.14

Thank you!
