web3 was working fine. But I don't know why web3 doesn't install anymore from today. I could use web3 1.2.1 previously in my other projects but it simply doesn't work anymore.Tried all solutions but still couldn't figure out.

`E:\Godfather\Smart Contracts\demo>npm install -g web3

sha3@1.2.3 install C:\Users\Godfather\AppData\Roaming\npm\node_modules\web3\node_modules\sha3
node-gyp rebuild
