What causes "File not found: ${options.path}" in shadcn-ui/ui?

Verify the file exists under config.resolvedPaths.cwd.

File not found

Error message

File not found: ${options.path}

What it means

Thrown by migrateRtl when a non-glob --path resolves to no filesystem entry (fs.stat returns null). Identical guard to migrate-radix's 'File not found' check, applied before any RTL transform work. The migrator will not attempt to read a non-existent file.

Solutions

Verify the file exists under config.resolvedPaths.cwd.
Check terminal cwd matches the project root.
On Linux, verify exact case of the path.

Example fix

// before
shadcn migrate rtl --path ./src/componets/ui/sidebar.tsx

// after
shadcn migrate rtl --path ./src/components/ui/sidebar.tsx

Defensive patterns

Strategy: validation

Validate before calling

import fs from 'fs/promises'
import path from 'path'

async function assertFileExists(rel: string, cwd: string) {
  const stat = await fs.stat(path.resolve(cwd, rel)).catch(() => null)
  if (!stat) throw new Error(`File not found: ${rel}`)
}

await assertFileExists(options.path, config.resolvedPaths.cwd)

Try / catch

try {
  await migrateRtl(config, { path: rel, yes: true })
} catch (e) {
  if (e instanceof Error && e.message.startsWith('File not found:')) {
    logger.warn(`Skipping RTL migration for missing path: ${rel}`)
  } else throw e
}

Prevention

Validate CLI-provided paths with fs.stat before dispatching.
Resolve against config.resolvedPaths.cwd, not process.cwd().
On case-sensitive filesystems, verify exact case.

When it happens

Trigger: Running `shadcn migrate rtl --path ./missing.tsx`; relative path resolved against an unexpected cwd; typo; file removed before the command ran.

Common situations: Wrong working directory; stale path from a renamed file; case mismatch on case-sensitive filesystems.
