create-react-app is failed to create project with typescript option

[KalpanaPagariya]

Is this a bug report?

Yes. I am facing below issue while creating new react app with typescipt:
D:\app>create-react-app my-app --scripts-version=react-scripts-ts

Creating a new React app in D:\learning\reactjs\my-app.

Installing packages. This might take a couple of minutes.
Installing react, react-dom, and react-scripts-ts...

Below is the npm config change:
I am working in my office having some firewall setup.
Below is the setup I did for proxy in npm config. I changed proxy and https-proxy to my office n/w proxy because npm install was failing

D:\myapp>npm config list
; cli configs
metrics-registry = "http://registry.npmjs.org/"
scope = ""
user-agent = "npm/5.6.0 node/v8.9.4 win32 x64"

; userconfig C:\Users\kalpanap.npmrc
https-proxy = "http://xxxxxx:8080/"
proxy = "http://xxxxxx:8080/"
registry = "http://registry.npmjs.org/"
strict-ssl = false

; builtin config undefined
prefix = "C:\Users\kalpanap\AppData\Roaming\npm"

[Timer]

I'm not sure how we can help here, it looks like you need to configure npm to authenticate to your on-prem registry. You can file an issue with npm for help with this.
