I'm trying to install the Authoring tool.  I've gone through the 'install on server steps' but after cloning the adapt_authoring project and running npm install --production, I get the warnings/errors below.

Can anyone advise please?

[server1 adapt]# git clone https://github.com/adaptlearning/adapt_authoring.git
