No lockfile was found in your project

Error message

No lockfile was found in your project (one of ${StudioServerInternals.lockFilePaths
				.map((p) => p.path)
				.join(', ')}). Install dependencies using your favorite manager!

What it means

Thrown by the upgrade command when StudioServerInternals.getPackageManager returns 'unknown', meaning none of the recognised lockfiles (package-lock.json, yarn.lock, bun.lockb, pnpm-lock.yaml, etc. - listed in StudioServerInternals.lockFilePaths) were found at or above the remotion root. Without a lockfile Remotion cannot infer which package manager to invoke for the upgrade.

Solutions

1. Install dependencies once with your package manager (`npm install`, `yarn`, `bun install`, or `pnpm install`) to generate the lockfile, then re-run `npx remotion upgrade`.
2. Run the command from the project root that contains (or should contain) the lockfile.
3. Pass --package-manager explicitly if your workflow uses a non-detected setup.

Example fix

// before - no lockfile present
$ npx remotion upgrade
// after - generate lockfile first
$ bun install
$ npx remotion upgrade

import {existsSync} from 'node:fs';

const LOCKFILES = ['package-lock.json', 'yarn.lock', 'bun.lockb', 'pnpm-lock.yaml'];

const ensureLockfile = (root: string) => {
  if (!LOCKFILES.some((f) => existsSync(`${root}/${f}`))) {
    throw new Error(`No lockfile found in ${root}. Run your package manager's install first.`);
  }
};

ensureLockfile(remotionRoot);

const hasLockfile = (root: string): boolean =>
  LOCKFILES.some((f) => existsSync(path.join(root, f)));

When it happens

Trigger: Running `npx remotion upgrade` (or `npx remotion add`) in a directory that has no lockfile - e.g. a fresh project where dependencies were never installed, or a directory that is not the project root.

Common situations: Cloning a repo whose lockfile is gitignored; running the command in a subdirectory; a project that uses an unsupported/custom package manager; a fresh `git init` with package.json but no install yet.
