Bench is Stuck after 'Bench Start'

I’m using Mac OS Catalina and tying to use FrappeFramework. I followed the procedure from FrappeFramework website and everything was installed properly.
Even the ‘bench init frappe-bench’ was executed properly.
But after executing ‘bench start’ it gets stuck on ‘Rebuilding data_import_tools.min.js’. I left my computer open for half hour and still it is not going anywhere and there is no error shown anywhere.

So please help me in this situation. Thank you.

This is not the recommended mode of installation for production. Instead, install the package from PyPI with: `pip install frappe-bench`

Open the site in a browser http://yourERPNextIP:8000 and see what happens

What you are looking at is the stdout run-time logging of your ERPNext server up and running and waiting for you to do something on the client.

You are seeing exactly what you are supposed to be seeing.

You want to leave it like that, but open another terminal window to continue issuing further bench commands. Some commands like bench --site your.site migrate have a tendency to kill the server. Because of that you should check back to your server window from time to time, ready to type bench start again if necessary.

As in other thread, Frappe can’t live on Catalina. Mojave is the most.
I do dual boot Catalina and Mojave and use Mojave as my development boot.
