Morning all,

I'm trying to install the authoring tool and I keep running into a node error when the tool's install script attempts to install the node modules in the framework. 

I have 0.6.5 of the authoring tool and I am attempting to install with 4.0.1 of the framework.

The install script gets to the part where it must install the master tenant. It appears to be successfully cloning the framework and falling over when installing it's dependencies. I've included the output of the install script and the output of the debug log below.

I am currently using node 8.12.0 and npm 6.4.1.

I have tried this with node 10.15.1 and got the same output, I have tried `npm cache clean --force` but it doesn't seem to have any effect. 

This is on an internally accessible server that uses apache to proxy adapt.

I think that this might be a node issue rather than an adapt issue, I wondered if anyone else had come across something like this before?

Thanks for any help
Nicola


Install script:

```

Now configuring the master tenant.

> Set a unique name for your tenant (master)
> Set the display name for your tenant (Master)

Tenant 'master' already exists. It must be deleted for install to continue.
> Continue? (Y/n) (Y)
