Node-gyp build error on mac for npm install - node.js

Question

I have an Angular app and I am trying to set up it in my local Mac machine. But when I use npm install to install the dependencies, I get the following error

Answer 1

The U mode has been deprecated for a while, and was finally removed in Python 3.11.
Unfortuantely, gyp still uses this mode, and is thus incompatible with Python 3.11 (see, e.g., https://github.com/nodejs/node-gyp/blob/main/README.md#on-macos). Downgrading to Python 3.10 should solve the issue.
