Error: PostCSS plugin postcss-prefix-selector requires PostCSS 8.

[sidoruk-sv]

Starting to get such error with a minor update to postcss-prefix-selector@1.11.0.

Interesting how that happened (see that in deps, there where postcss 8 for a long time already).

help me !!!

Uncaught Error: Module build failed (from ./node_modules/_svg-sprite-loader@6.0.9@svg-sprite-loader/lib/loader.js):

An urgent fix is required. Thank you

@kshiw @sidoruk-sv Please try to npm install again. Version 1.11.0 contained a breaking change, I published a new version 1.12.0 that fixes this.

Ah, maybe this will fix this:

...checking

[danielweck]

I confirm that updating postcss-prefix-selector to the hotfix release 1.12.0 transitively fixes svg-sprite-loader.
Phew! :)
Thank you for addressing this regression bug quickly.

Looks like everything went back to normal so I'm closing this one. Thanks for reporting it!

[sidoruk-sv]

@RadValentin indeed, all is working now.

Thank you for lightning fast hotfix!)
