Bug description

v7.8.3 is working fine, but all the v8 versions are giving me the same error:

[!] (plugin postcss) TypeError: o is not a function
src/global.pcss
TypeError: o is not a function
    at /node_modules/postcss-preset-env/dist/index.cjs:1:17553

    at LazyResult.runAsync (/node_modules/postcss/lib/lazy-result.js:433:21)

This error is thrown even if my used src/global.pcss file is completely empty.

Hi @ERuseckas,

Thank you for reaching out about this!

Can you remove 'environment-variables': true from your config?
I think that should make the error go away.

https://github.com/csstools/postcss-plugins/blob/main/plugin-packs/postcss-preset-env/CHANGELOG.md#800-january-24-2023

From the changelog :

Removed postcss-env-function (breaking).

If you depend on this feature you must add it separately as a dependency in package.json and in your PostCSS config :

		require('postcss-mixins')({
			mixinsFiles: path.resolve(__dirname, 'src/common.pcss')
		}),
		require('postcss-env-function')(),
		require('postcss-preset-env')({
			stage: 2,
			preserve: false,
			features: {
				'custom-media-queries': true,
				'custom-properties': false,
				'custom-selectors': true,
				'environment-variables': true
			}
		}),
		require('postcss-nested')(),

---

We will roll out a patch shortly to ensure this exception doesn't happen.

Thank you @romainmenke
Removing that line helped

@ERuseckas This exception has also been resolved in the latest release of postcss-preset-env. If you encounter a similar case the plugin will give you more useful feedback on what is going on.

Thank you again for reporting this!
