hi guys, I tried to install fuels TS sdk package using npm but it didn’t work, also tried yarn but ended up with the same error.

> npm ERR! node:internal/streams/writable:444  
> npm ERR! const state = stream.\_writableState;  
> npm ERR! ^  
> npm ERR!  
> npm ERR! TypeError: Cannot read properties of undefined (reading ‘\_writableState’)  
> npm ERR! at \_write (node:internal/streams/writable:444:24)  
> npm ERR! at Writable.write (node:internal/streams/writable:494:10)  
> npm ERR!  
> npm ERR! Node.js v20.10.0

Is it possible for you to share your repo? I’m unable to reproduce this error with NodeJS v20.10.0 with a simple vite vanilla-ts repo.

Thanks for you reply, I haven’t started anything yet, just create empty folder and start install fuelsSDk using command “npm i fuels” and this error happened.

@Cku2411 have you tried this on WSL for Windows? For now, that would be the only way to make this work on Windows. We are working hard on a fix though, which should be out soon.
