npm install netsmarttech / mpi-s7
Thanks for help

Do you have a shell license installed?
If not, go here and get one; Opto22 - GROOV-LIC-SHELL - License to access Linux<sup>®</sup> operating system on <em>groov </em>EPIC or <em>groov</em> RIO through a secure shell

Once you have shell up and running you can then start to work on installing the libraries that the package requires.

Hi

When i use npm install netsmarttech/mpi-s7 i have this message :
fatal error: libudev.h: No such file or directory

if i use the command : sudo apt-get install libudev-dev i have this message :
Package libudev-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package ‘libudev-dev’ has no installation candidate

I don’t know what i do.

Thanks
