Turbopack Error: Permission denied (os error 13)

[Tsiaro05052004]

Turbopack version: 731ace46
Next.js version: 0.0.0

Error message:

Permission denied (os error 13)

Permission denied (os error 13) usually means Turbopack can't read or write somewhere in the project/build environment. I'd try clearing the generated cache first:

rm -rf .next .turbo
npm run dev

If it still happens, check that your user has read/write permission for the project directory and that .next isn't owned by another user (for example, after running a previous command with sudo). On Windows, also check whether Defender/antivirus is blocking writes.

If you're using WSL, make sure the project is in a location where your Linux user has full access rather than a restricted/mounted directory.

If none of these helps, the full error output with the file/path Turbopack is trying to access would be useful for pinpointing the permission issue.
