tns doctor command does not report any information on CircleCI MacOS virtual machines

[cowboyd]

Environment
Provide version numbers for the following components (information can be retrieved by running tns info in your project folder or by inspecting the package.json of the project):

The tns info command does not actually report either on the CircleCI vm:

bash-3.2$ yarn tns info
yarn run v1.12.1
$ /Users/distiller/project/node_modules/.bin/tns info
✨  Done in 6.89s.
bash-3.2$

But this is what I get when running it on my local Mac:

❯❯❯❯ yarn tns info                                                 ~/C/F/n/vacation-tracker jc/circle-workflow
yarn run v1.13.0
$ /Users/cowboyd/Code/Frontside/nativescript-playground/vacation-tracker/node_modules/.bin/tns info

Describe the bug

tns doctor and other commands do not actually render critical output. For example, this is output of the tns doctor command on a Circle MacOS VM:

bash-3.2$ yarn tns doctor
yarn run v1.12.1
TIP: To avoid setting up the necessary environment variables, you can use the Homebrew package manager to install the Android SDK and its dependencies.

There seem to be issues with your configuration.
You are missing the nativescript-cloud extension and you will not be able to execute cloud builds. Your environment is not configured properly and you will not be able to execute local builds. To continue, choose one of the following options:
Select "Sync to Playground" to enjoy NativeScript without any local setup. All you need is a couple of companion apps installed on your devices.
Select "Configure for Cloud Builds" to install the nativescript-cloud extension and automatically configure your environment for cloud builds.
Select "Configure for Local Builds" to run the setup script and automatically configure your environment for local builds.
Select "Configure for Both Local and Cloud Builds" to automatically configure your environment for both options.

To Reproduce
SSH into a CircleCI virtual machine and run the command tns doctor

I'd be happy to work with anybody wanting to ssh into this virtual machine and debug it.

Expected behavior

tns doctor command logs diagnostics to console.

Hey @cowboyd ,
Thank you very much for bringing this issue to our attention. We have investigated it and applied a fix, that will be released with NativeScript CLI 5.2.1. You can test it immediately by installing rc version of CLI: npm install -g nativescript@rc
You can find more information what causes the issue in the related PR: #4404
