I am unable to install any modules (nodes) in Node-RED on hassio running on a Raspberry Pi. It worked previously, but does not now. I have not changed any configuration although it is possible that node-red auto updated. When I attempt to install, I get this error:
npm info it worked if it ends with ok
npm info using npm@5.6.0
npm info using node@v10.0.0

There is no proxy. I tried to edit package.json to add the modules to dependencies but that also did not work.
It was a DNS problem. Pi-Hole was also running on the RPi and causing the issue. Set DNS to Google using this info.
