Current Behavior

Observed 🔭 on the npm v11 shipped ⚓ with Node.js:

After setting npm config set node-gyp <path> to globally 🌐 installed version of node-gyp on Windows npm continues to use built-in node-gyp no matter what.

Expected Behavior

After setting npm config set node-gyp <path> to the new path npm should pick up that path to run node-dyp during execution of npm install.

Steps To Reproduce

1. Install node-gyp globally: npm install node-gyp -g
2. Set node-gyp global path in npm config: npm config set node-gyp $(echo "${ npm ls -g node-gyp --parseable; }\bin\node-gyp.js")
3. Run: npm install @confluentinc\kafka-javascript --foreground-scripts --loglevel=silly
4. See error and observe that built-in node-gyp still in use:

gyp info it worked if it ends with ok
gyp verb cli [
gyp verb cli 'C:\\Program Files\\nodejs\\node.exe',
gyp verb cli 'C:\\Program Files\\nodejs\\node_modules\\npm\\node_modules\\node-gyp\\bin\\node-gyp.js',
gyp verb cli 'clean'
gyp verb cli ]
gyp info using node-gyp@12.4.0
gyp info using node@26.5.1 | win32 | x64
