[bug] Python 3 needed to install

[StrangerGithuber]

Hello
I am running this command npm install -g @soketi/pws and I get these errors but I don't know why:

npm WARN deprecated querystring@0.2.0: The querystring API is considered Legacy. new code should use the URLSearchParams API instead.
npm WARN deprecated uuid@3.3.2: Please upgrade  to version 7 or higher.  Older versions may use Math.random() in certain circumstances, which is known to be problematic.  See https://v8.dev/blog/math-random for details.

I am a newbie so no idea what can be the problem. I see something python related but no idea if I need to install and if I need to install then which version I need.

Thank you in advance the help.

That's a weird thing you need Python 3.x for it to compile...

I did install the newest python and I don't get the errors but I get the first two lines:

npm WARN deprecated querystring@0.2.0: The querystring API is considered Legacy. new code should use the URLSearchParams API instead.
npm WARN deprecated uuid@3.3.2: Please upgrade  to version 7 or higher.  Older versions may use Math.random() in certain circumstances, which is known to be problematic.  See https://v8.dev/blog/math-random for details.

This is not an issue. There are just usual warnings that are not so important because UUID is not using random IDs for security. This is still a bug because Python 3 is not needed when installing it, so I should definitely solve this 😁

One of the dependencies triggers a node-gyp rebuild, which does require a compatible version of Python to run. As of right now Node.js does have a dependency on gyp which is a Python library for project generation taken directly from the V8 JavaScript engine. Therefore I can only recommend to install Python on your machine if you are planning to use Node.js on the regular.
