Summary

I'm got struggled in build app. It works on my Linux but Windows.

This is the commands I have used:

1. npx create-next-app@latest
2. npm run build

And I got

❯ npm run build

> my-app@0.1.0 build
> next build

   ▲ Next.js 15.2.4

   Creating an optimized production build ...
Failed to compile.

Error: EISDIR: illegal operation on a directory, readlink 'D:\desktop\111\my-app\app\favicon.ico'

My environment:

I have tried:

1. Remove all .npmrc files
2. Uninstall Node.js and install it again (have deleted C:\Users\[User]\AppData\Roaming\npm and C:\Users\[User]\AppData\Roaming\npm-cached)

Does it work, if you have the project in another disk? Like C:?

[Canis-Infinity]

It works in C:! But why it works? Any solutions🥲?

[icyJoseph]

I think, I read online, that the disk formatting might mess up symlinks? https://stackoverflow.com/questions/77187261/how-do-i-resolve-an-eisdir-error-on-windows-when-running-npm-link

I'll try to reformat my disk from exFAT to NTFS and give feedback.

[Canis-Infinity]

It's solved! Thanks for your help!
Solution: The disk needs to be NTFS.
