Hi, I don't know why but get this error when execute npm i windows-build-tools -g :

This appears to be caused by a problem with your network. https://github.com/nodejs/node/issues/5436#issuecomment-188917703

What happens when you try to download the installer directly? e.g.

$ wget https://www.python.org/ftp/python/2.7.15/python-2.7.15.amd64.msi

You may want to try using a different Python mirror (e.g. --python-mirror argument or PYTHON_MIRROR environment variable).

Thank you for your support

the wget command doesn't work for me

I tried from another pc and this command: npm i windows-build-tools -g works, so the problem is only on my personal pc

How is it possible? what's can be the problem?

Hi, I solved it with this command: npm config delete proxy

I don't know why but now it's working all perfectly

Do you have any idea about what's up?

However thank you for your time and support!

It's not included with Windows; you'd have to download and install it. I didn't mean to imply that you had to use that tool though. It's just a CLI HTTP/HTTPS/FTP client. You could've tried the URL in a standard web browser instead or performed just the DNS lookup portion using nslookup.

Do you have any idea about what's up?

It seems likely that your computer's proxy settings (or other network configuration) are not set correctly. It is unlikely to be related to windows-build-tools at all.
