But the address is valid - do you have any filtering taking place on your network/computer?
maybe an issue with internet?

No, I didn't do any filtering. However, I tried some solutions that I found on a website. The issue was a Windows build tool error, since I'm using a Windows environment. So, I downgraded Node from 18.11 to 17.9 and installed the Windows build tool. Now everything is working perfectly, and I can also use TensorFlow Node.

Anyway, I have another concern. Will Node Version 17.9 cause any other issues, such as security or compatibility issues?

There is always a security concern - but that is life!

As for Node version, Node RED requires >= 14, but other nodes you install may have a higher minimum version, if such requirements are needed, usually the node author(s) should make reference to the min version.

Just be mindful that Node 17 will no longer recieve updates, but in most cases should not be too much of a threat.

Node RED in the future version may increase the min version

Agreed. Do you have any idea why windows build tool is not able to install in node version 18

6

I don't - I'm not a window user sadly.

When installing Node 18 for windows, did you include all the build tools that come with the installer? the Node 18 installer, includes the necessary tooling - but you have to enable them
