Needed to run: npm install --save-dev @types/node in order for the server to build correctly

[surfnerd]

I needed to run npm install --save-dev @types/node in the Server~ directory to allow the server to start correctly.

I'm on a Mac M3Max on macOS 15.5 (24F74).

❯ npm run build

> mcp-unity-server@1.0.0 build
> tsc

error TS2688: Cannot find type definition file for 'node'.
  The file is in the program because:
    Entry point of type library 'node' specified in compilerOptions

  tsconfig.json:14:15
    14     "types": ["node"]
                     ~~~~~~
    File is entry point of type library specified here.


Found 1 error.

Thank you for your report @surfnerd

Did you run the "Force Install Server" button in Unity?
What happens when you do "npm install" in your server folder?

Hey @CoderGamester,
I did try "Force Install Server" from Unity.

here are the logs:

[MCP Unity] Exception while running npm install in ~/project/Library/PackageCache/com.gamelovers.mcp-unity@b4b4bd627794/Server~. 
Error: ApplicationName='/opt/homebrew/bin/npm', CommandLine='install',
CurrentDirectory='~/project/Library/PackageCache/com.gamelovers.mcp-unity@b4b4bd627794/Server~',
Native error= Cannot find the specified file

This is what led me down the rabbit hole to try installing @types/node

Note: I modified the log to remove any personal information.

I'm also using Unity 6000.2.0b2

[surfnerd]

I got it working, but I just wanted to let you know in case this was a bug that other people could run into.

[CoderGamester]

@surfnerd thank you very much for report
There is definitely something going wrong and I am looking into it

Thank you again
