Error while linking app to Splunk directory on Putty

[POR160893]

Hi,

I am creating a React app for Splunk on a Putty terminal. I am following the following tutorial:
https://splunkui.splunk.com/Create/AppTutorial

However, I am unable to build the output directory needed to be symlinked into Splunk's application directory with the command: 
yarn run link:app

I have set the $SPLUNK_HOME environmental variable to /opt/splunk but everytime I run the yarn run link:app command, I keep getting the following error:

node: error while loading shared libraries: libcrypto.so.1.0.0: cannot open shared object file: No such file or directory


How can this be solved please? 


Thanks,
