css-modulesify / autoprefixer postcss version mismatch?

[zaim]

I got this error while trying to use css-modulesify with autoprefixer: Your current PostCSS version is 4.1.16, but autoprefixer uses 5.0.8. Perhaps this is the source of the error below.

Not sure if its something wrong with my browserify command incantation, or what.

Full output below:

de_modules/.bin/exorcist public/js/bundle.js.map > public/js/bundle.js
Your current PostCSS version is 4.1.16, but autoprefixer uses 5.0.8. Perhaps this is the source of the error below.

@zaim can you please give us a link to the repo so we can see the bug in action?

[zaim]

You mean my project's repo? It's a personal project, not yet open sourced. What kind of information would you need? Maybe I can post my package.json and Makefile in a gist?

[joshwnj]

Yes a gist would be good thanks. Just something so that we can reproduce the bug, and understand all of the factors at play.

autoprefixer@latest (6.0.3) uses postcss@5.0.8
css-modulesify@latest (0.9.0) uses postcss@4.1.16 (via css-modules-loader-core@0.0.12)

@zaim you can fix this issue by downgrading your autoprefixer (npm i --save-dev autoprefixer@5.x). Using the older package isn't ideal but that's how I'm getting around this for now.

@joshwnj you may want to consider updating css-modules-loader-core and subsequently css-modulesify to use postcss@5.x so that css-modulesify can work with the latest postcss plugins.

[themitchy]

This and many other bugs will get fixed by #47

[joshwnj]

@zaim can you please confirm whether this issue is fixed now that we're on postcss v5?

[huan086]

I'm running css-modulesify 0.16.1 with autoprefixer 6.3.1. I don't see the error.

[joshwnj]

Closing as this is most likely resolved now
