Transform Error when using unocss.config.ts as configuration file

[JSFTI]

When using unocss.config.ts as configuration file, npm run dev returns error.

Dependencies

vite.config.ts

unocss.config.ts

However, if unocss.config.ts is removed, npm run dev runs successfully. Am I missing something?

Can you share a minimal reproduction? Thanks.

Same here (quasar2 + vite). Error appears from unocss v0.35.0. Reverting back to v0.34.1 eliminates the error

<path to app>/node_modules/@unocss/transformer-directives/dist/index.mjs:2
var _cssTree = require("css-tree");
               ^

Error: TRANSFORM_ERROR: Export namespace should be first transformed by `@babel/plugin-proposal-export-namespace-from`.

Gladly,
First, I create a new Vite project by pnpm create vite, and choose react as the framework and react-ts as variant

Changed active directory to vite-project and run pnpm i

Installs unocss with pnpm i unocss

Import and add Unocss() to vite.config.ts plugin array.

Create unocss.config.ts file

This is the current directory structure

Run npm run dev to start development server

Error occurs.

However, if unocss.config.ts is removed, no error occurs and unocss will work as intended.

Forgot to mention that uno.css is imported in main.tsx

This was already fixed by #1016, just it's not released yet.
Seems like there is no way to link a closed pull request.

I see, I guess the best course of action is to revert to 0.34.1 as mention by Sfinx. Thank you for your help.

Published v0.35.2
