vuepress: Error in build (postcss_1.default is not a function)

This error appeared after I cleared my modules directory and reinstalled from scratch (no package-lock.json). I cleared npm cache, and tested on a completely blank project with only a single readme.md file with no configuration changes and it fails in the exact same way.

OS: Window 10 Node: 9.5.0 VuePress: 0.8.4 Local install (npm)

Error message:

ERROR in ./site/.vuepress/theme/Page.vue?vue&type=style&index=0&lang=stylus (./node_modules/css-loader??ref--11-oneOf-1-1!./node_modules/vue-loader/lib/loaders/stylePostLoader.js!./node_modules/postcss-loader/lib??ref--11-oneOf-1-2!./node_modules/stylus-loader??ref--15-oneOf-1-3!./node_modules/vue-loader/lib??vue-loader-options!./site/.vuepress/theme/Page.vue?vue&type=style&index=0&lang=stylus)

Reported an issue (https://github.com/vuejs/component-compiler-utils/issues/9) to @component-compilter-utils, please wait patiently.

This issue didn’t exist yesterday when I performed a clean install, so it’s most likely the result of a release from the last day or so.

@dolare No problem! the resolutions attribute is great for when this happens or when you need to keep a dependency “flat” across all modules of an app

@dolare @bayssmekanique

Instead of messing up with compileStyle.js, add this to your package.json:

    "resolutions": {
        "@vue/component-compiler-utils": "1.1.0"
    }

This will use the previous version of @vue/component-compiler-utils and everything will work as expected!

I’m fairly certain the bug is in https://github.com/vuejs/component-compiler-utils/commit/1456e3dc07c260dad276356be778a0dcb9fc6787
