Build error adding sdk to project

[ArkeBcacy]

Describe the bug
Going through the tutorial here and when I run npm start the command fails with the error:

PS C:\Prj\MCP\Server\Weather> npm start                                   

> weather-mcp-server@1.0.0 start
> node build/index.js

node:internal/modules/esm/resolve:215
  const resolvedOption = FSLegacyMainResolve(packageJsonUrlString, packageConfig.main, baseStringified);
                         ^

Error: Cannot find package 'C:\Prj\MCP\Server\Weather\node_modules\@modelcontextprotocol\sdk\package.json' imported from C:\Prj\MCP\Server\Weather\build\index.js

}

Attempted to build the latest 1.17.4 SDK code locally and received the error:

PS C:\Prj\MCP\SDK\TS\typescript-sdk> npm run build

> @modelcontextprotocol/sdk@1.17.4 build
> npm run build:esm && npm run build:cjs


> @modelcontextprotocol/sdk@1.17.4 build:esm
> mkdir -p dist/esm && echo '{"type": "module"}' > dist/esm/package.json && tsc -p tsconfig.prod.json

The syntax of the command is incorrect.

To Reproduce
Steps to reproduce the behavior:

1. Cloaned the GIT Repo
2. Ran npm install
3. Ran npm build

Expected behavior
Expectation is that the typescript sdk works when pulling it into a project as outlined in the documentation

Running this with Windows 11 and latest VS Code for reference.

The syntax of the command is incorrect.
This happening because you’re on Windows (PowerShell / CMD), and the mkdir -p and echo > file syntax is Unix-only.

Use Git Bash instead of PowerShell/CMD to run npm run build on Windows.

Shouldn't this project's build actions actually build the dist folder and include it in the package so I don't have to mess around with trying to build it locally?
