CSS build issues

[stephenplatz]

I thought I'd open an issue here, although I'm not sure if this could actually be related to gohugoio/hugo#7278 (comment). In any case, I'm still getting the POSTCSS: failed to transform "css/main.css" error when I try to build the site, despite making sure all of the dependencies in the documentation are installed.

I'm not actually using a snap installation of Hugo, though Hugo Static Site Generator v0.71.1-A301F6B2/extended linux/amd64 BuildDate: 2020-05-25T09:18:12Z

check if you installed npm dependencies properly, I had the same issue

you need to run npm commands inside the hugo projects

I'm getting this error also. I've created a new hugo site and added this theme as a submodule. I'm able to serve locally, but not able to build.

My environment:

• node v12.18.1
• Hugo Static Site Generator v0.72.0/extended darwin/amd64 BuildDate: unknown

Error: Error building site: POSTCSS: failed to transform "css/main.css" (text/css): resource "sass/sass/style.sass_b1195a7e151e6f4379f823b1b2b4f87a" not found in file cache

Ok nvm I was able to fix this by reading this post. I ran these two commands and I was able to build:

sudo npm i -g postcss-cli
sudo npm i -g autoprefixer

Thank you for sharing @gray419!

Hello, I'm having the same issue, using the theme via gitlab-ci.
Would anyone have a suggestion on how the issue could be solved in that context? I don't know if the solution proposed by @gray419 can be applied in such docker environment.

@eauchat , I fixed the same issue by adding a package.json file, with the following content :

{
  "name": "netlify-deps",
  "version": "0.1.0",
  "dependencies": {
    "postcss-cli": "7.1.1",
    "autoprefixer": "9.8.4"
  }
}

I did not try with gitlab-ci, I use netlify. By default, Netlify runs npm install to install the dependencies listed in my package.json file. So, if you configure your CI to install the dependencies, the issue will be solved.

@dannie-ml If you provide some error feedback, information about your set up, or a link to your site repository, we can try and help! 😄

For folks who find this issue because they are still tripping over the error:

POSTCSS: failed to transform "css/main.css"

I added the package.json shown in this comment and I still had the error, because I forgot to run:

npm install

This cleared the error for me.
