Expo React Native Nati Base project tailwind(native) build failed

I am trying to build react native expo app using npx create-expo-app -e with-router-tailwind After creating the project and running I get a tailwind build failed error. I tried node D:\Projects\Chat 101 (APP)\chat-101-master\node_modules\tailwindcss\lib\cli.js --input "D:\Projects\Chat 101 (APP)\chat-101-master\src\global.css" --output "D:\Projects\Chat 101 (APP)\chat-101-master\node_modules\.cache\nativewind\global.css.native.css" --watch and its successfully compiled without errors but when I npm start and open in expo go its build failed.

Found 2 ways to fix the issue, its related to nativewind - one of the packages in the project.

FIRST

reference to folder structure of with-router-tailwind project you mentioned above, head to your _layout.tsx and replace import "../global.css"; with import '../../node_modules/.cache/nativewind/global.css' this should enable the build to go through / prevent freezing of the build

ALTERNATIVE SOLUTION (I recommend this)

open your node_modules folder and locate nativewind - follow this directory \node_modules\nativewind\dist\metro\transformer.js

here, replace return metro_transform_worker_1.default.transform(config, projectRoot, filename, Buffer.from(require('${config.nativewind.output}');, "utf8"), options);

with

return metro_transform_worker_1.default.transform(config, projectRoot, filename, Buffer.from(require('${config.nativewind.output.replace(/\/g, '\\')}');, "utf8"), options);

i added .replace(/\/g, '\\') to the output to curb the isssue

Hope this helps, happy coding
