I've ran into a problem trying to install web3. I went through here and stackover flow to try and solve the issue but had no success. I had to install python2.7 but still getting this error. Any ideas where I am going wrong? Thanks.

Try this:

npm install --global --production windows-build-tools
  • And prepare yourself for a nightmare (unless you're lucky enough to have all the related stuff which was previously installed on your machine, configured precisely as windows-build-tools wants it to be; I once to reinstall Windows 10 completely from scratch in order to make it work). – goodvibration Sep 16 '19 at 17:24
  • Thanks for your help. I resolved the issue. Also found this article for reference incase there are any other problems spin.atomicobject.com/2019/03/27/node-gyp-windows – kingy2826 Sep 18 '19 at 7:49
