Use when Windows npm run, npm test, npm run build, or npm run-script exits before running the script with ERR_INVALID_ARG_TYPE, "file argument must be of type string", missing ComSpec, broken script-shell, stripped CLI flags, sandboxed npm cache/log EPERM, or silent npm script output.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Windows Npm Run Script Shell ## Overview Windows npm scripts need a shell. If `ComSpec` is missing or npm cannot infer a script shell, `npm run ...` can fail inside npm before `tsc`, Vite, Vitest, or Playwright actually runs. ## Triage Use this flow before changing app code: 1. Run the target tool directly with `npx`, for example `npx tsc -b --pretty false`, `npx vite build`, or `npx vitest run`. 2. Run `npm run <script> --loglevel verbose`. 3. Open the npm debug log if output is empty. 4. Check shell config: ```powershell npm config get script-shell npm config get cache npm config get update-notifier Write-Host "ComSpec=[$env:ComSpec]" Write-Host "SHELL=[$env:SHELL]" ``` If direct `npx` commands pass but `npm run` fails with `ERR_INVALID_ARG_TYPE: The "file" argument must be of type string. Received undefined`, treat it as npm shell configuration, not a project build failure. If direct `node <script>` succeeds but `npm test`/`npm run` exits silently in a sandbox, rerun with `--loglevel verbose`. When npm reports `EPERM` creating `%LocalAppData%\npm-cache\_logs` or attempts registry access only for update checks, treat it as npm runtime side effects, not a test failure. …

How to install
mdr add jinning6/noosphere/windows-npm-run-script-shell@sha256:7af3dc0b48d2fef4The line at the top of this page pins the label git:20260715.10fc9a0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
