Recently I got an issue when creating a new route using Tanstack Router + Vite
So by adding this config could solved the issue of EPERM: operation not permitted like below:
CODE
Error: EPERM: operation not permitted, rename 'D:\IMT\imt-fe\.tanstack\tmp\884d3334-4715af826dad72bfa663dbba03a36060' -> 'D:\IMT\imt-fe\src\routes\users\$phone_number\edit.tsx'

By adding usePolling and stabilityThreshold props into vite.config.ts, the route creation happen like magic during development process (a bit slow but your server won't shut)
vite.config.ts
CODE
const config = defineConfig({
.... your other config ....
// solves EPERM
server: {
watch: {
usePolling: true,
interval: 300,
awaitWriteFinish: {
stabilityThreshold: 500,
pollInterval: 100,
},
}
}
})
Note: This config doesn't depend on specific OS/hardware settings. If you still encounter similar issues when generating multiple routes at once, simply increase the stabilityThreshold interval slightly (e.g., 500 → 800) as a further adjustment.
