调研方向

使用 npx react-native init-windows --overwrite 重现该失败，然后检查 react-native-windows/react-native.config.js 以及 @react-native-windows/find-dotnet-tools 的加载路径。检查 rnw-dependencies 页面和包依赖元数据，以确认缺失的 PowerShell 和 runtime-package 要求。选定的修复方案已针对报告的 0.81.x 和 0.83.x 行为完成验证，即表示完成。

描述

bug Needs: Triage :mag:

Problem Description

On a fresh project, npx react-native init-windows --overwrite fails with:

error: unknown command 'init-windows'

The actual root cause is that react-native-windows's plugin throws at module-load time inside @react-native-windows/find-dotnet-tools when pwsh.exe is not on PATH:

Unable to find pwsh.exe. It should have been made available by `yarn install`.

The community CLI silently swallows the throw during plugin discovery, drops the command, and reports "unknown command" instead of the real error.

PowerShell 7 is not listed on the rnw-dependencies page. Windows ships only Windows PowerShell 5.1 by default, so most fresh machines fail this check.

This affects both [email protected] and 0.83.x. Additionally, the 0.83.x line has a missing-dependency bug: @react-native-windows/find-dotnet-tools is not in any package's dependencies but is required at runtime. Even after installing pwsh, init-windows still fails on 0.83.x until the user runs yarn add @react-native-windows/find-dotnet-tools manually.

Steps To Reproduce

On a clean Windows 11 install without pwsh.exe on PATH:

npx --yes @react-native-community/cli@latest init Test --version 0.83-stable
cd Test && yarn add react-native-windows@^0.83.0
npx react-native init-windows --overwrite

Result: error: unknown command 'init-windows'
To see the real underlying error, run:

node -e "require('react-native-windows/react-native.config.js')"

`Unable to find pwsh.exe. It should have been made available by yarn install.`

Expected Results

Either:

init-windows plugin discovery is resilient to missing pwsh: defer the pwsh check until the command actually runs, so the user sees a clear "install PowerShell 7" message instead of "unknown command".
PowerShell 7 is documented as a prerequisite on the rnw-dependencies page, so users install it before reaching this step.
@react-native-windows/find-dotnet-tools is added to react-native-windows's (or @react-native-windows/cli's) dependencies so it's installed transitively rather than left as a manual yarn add.

Ideally all three.
