I can see in the node_modules/node-pty/scripts/install.js there is

const gypProcess = spawn(os.platform() === 'win32' ? 'node-gyp.cmd' : 'node-gyp', gypArgs, {
  cwd: path.join(__dirname, '..'),
  stdio: 'inherit'
});

But there is no node-gyp in the folder

Solved by pnpm i -D node-gyp, which is unusual, normally I don't need to do this.

Most modules don't have native code; this one does, hence node-gyp being necessary

node-pty should likely have node-gyp as a dependency to prevent this issue

Please try with the latest version, the node-gyp dependency is not required since https://github.com/microsoft/node-pty/pull/567
