NGrok required dependency installer issue

[gcsuk]

I am having some problems installing on our server.

I have executed the following:

npm install twilio-cli -g

where I got an exception saying the dependency ngrok cannot be downloaded – this is because ngrok is blocked by our firewall for security reasons.

I then tried:

npm install twilio-cli -g --no-optional

which worked, Twilio CLI is now installed globally on the server.

Next I tried to install the dependencies of the application itself, of which @twilio-labs/plugin-serverless version 1.7.1 is one, and this had the same problem as the CLI.

The problem here is that --no-optional throws the same error, so I believe ngrok is not an optional dependency but a required one.

Can ngrok be changed to be an optional dependency, or is there another way around this?
