install ubuntu 18.04 has lots of warnings and errors

[maiatoday]

npm install gives errors.

node-pre-gyp ERR! Tried to download(404): https://github.com/tessel/node-usb/releases/download/1.3.1/usb_bindings-v1.3.1-node-v57-linux-x64.tar.gz 
node-pre-gyp ERR! Pre-built binaries not found for [email protected] and [email protected] (node-v57 ABI, glibc) (falling back to source compile with node-gyp) 

and later

../libusb/libusb/os/linux_udev.c:40:10: fatal error: libudev.h: No such file or directory
 #include <libudev.h>
          ^~~~~~~~~~~
compilation terminated.

these errors did not stop it from working. So I am going to change the title to say it can install but there are lots of errors and warnings that may or may not indicate a problem.
