Create with Storybook add-on hangs on pnpm 11 under “Running commands for Storybook…”

从 Storybook add-on 命令和包管理器翻译入手，然后跟踪 runCommandsAndInstallDependencies，查看子进程与 Clack spinner 是如何协调的。使用提供的 pnpm 11 命令在真实 TTY 中复现，并验证 Storybook 设置是否完成，或显示 approve-builds prompt，而不是看起来像是卡住了。

Create Tanstack App

Describe the bug

If I run TanStack create with the Storybook add-on on pnpm 11, the CLI can appear to hang forever on:

Running commands for Storybook...

Example (same shape as other create reports; adjust version/flags as needed):

pnpm dlx @tanstack/cli@latest create tanstack-app \
  --framework react \
  --add-ons storybook \
  --no-git \
  -y

The create spinner never finishes that step. What’s actually happening is that TanStack runs the Storybook add-on command (npx storybook init -y --no-dev → pnpm dlx storybook … for pnpm users) with the spinner still active. On pnpm 11 (TTY + cold dlx cache), pnpm waits for interactive approve-builds input for esbuild, but that prompt is easy to miss under the spinner — so the TanStack CLI looks stuck.

This is a TanStack create UX/invocation issue: the parent owns the spinner and how the child is launched. Storybook’s JS has not started yet when the prompt appears, so Storybook cannot surface or answer it.

Your Example Website or App

N/A as a hosted app — this is a local TanStack CLI create hang and needs a real TTY (StackBlitz / non-TTY environments won’t show the same interactive approve-builds path).

Repro is the TanStack create command above (or interactive pnpm dlx @tanstack/cli@latest create choosing React + Storybook on pnpm 11).

Steps to Reproduce the Bug or Issue

1. Use pnpm 11+ in a real terminal (TTY).
2. Optionally clear the pnpm dlx cache so the approve-builds path is more likely:
   rm -rf "$(dirname "$(pnpm store path)")/dlx"
3. Run TanStack create with the Storybook add-on, e.g.:

pnpm dlx @tanstack/cli@latest create tanstack-app \
  --framework react \
  --add-ons storybook \
  --no-git \
  -y

4. See the CLI sit on Running commands for Storybook... / appear hung.
5. If you look carefully at the terminal (or pause the spinner), pnpm may be waiting on an approve-builds prompt for esbuild.

Expected behavior

As a user, I expected TanStack create to finish (or show a clear prompt I can answer). Instead it looks stuck on “Running commands for Storybook…” while the child is waiting on stdin.

Platform

• OS: macOS (also reported on other setups via the linked Storybook issue)
• Browser: N/A (CLI)
• pnpm: 11.18.0
• Node: 22+ / 24 (see https://github.com/storybookjs/storybook/issues/35668)

Additional context

Why this is on TanStack: create launches the Storybook add-on command and keeps the Clack spinner up for the whole child lifetime. Fixing visibility and/or passing pnpm allow-build flags is in that path (storybook add-on command + package-manager translation + runCommandsAndInstallDependencies).

Workaround for the underlying pnpm step (verified): if you run the child yourself,

pnpm --allow-build=esbuild dlx storybook@latest init -y --no-dev

Suggested fixes:

1. When the package manager is pnpm, run the Storybook add-on command as pnpm --allow-build=esbuild dlx storybook init -y --no-dev (flag before dlx).
2. Pause/stop the spinner when the child may need a TTY so pnpm’s approve-builds UI is visible.
3. Document the workaround until (1) lands.
