compilation fails on arm64 architecture when installing npm dependencies

[andresrcs]

When trying to compile the latest version of shiny-server (v1.5.18.987) on arm64 architecture (Raspberry Pi) the installation of npm modules fails because the checksum of rstudio/node-optimist doesn't match

~/shiny-server/tmp $ (cd .. && ./bin/npm  install)

This doesn't happen on x64 architecture, I know you do not support arm64 architecture but I would be really grateful if you could give me a clue on what could be going wrong. Compilation used to work smoothly with all previous versions of shiny-server on arm64 (I currently have v1.5.17.973 installed) so I have no idea what could be going wrong

I ran into the same problem when compiling it on Raspberry Pi as well. Updating the integrity for node_modules/optimist in npm-shrinkwrap.json did the trick.
