[framework7-cli] Error creating project on Windows 7

I try to create F7-based project for Electron on Windows 7. I run framework7 create --ui in console (that is in turn run as administrator). I am able to select project options in browser and run app creation.

I see the following in browser, but after several seconds app creation stucks:

Generating package.json
✔ Generating package.json
Creating required folders structure
✔ Creating required folders structure
Installing NPM Dependencies (Please wait, it can take a while)
✔ Installing NPM Dependencies
Installing NPM Dev Dependencies (Please wait, it can take a while)
✔ Installing NPM Dev Dependencies
Executing NPM Scripts
✔ Executing NPM Scripts
Creating Cordova project (Please wait, it can take a while)

I see the following output in console:

d:\projects\electron\cordova-f7-electron-2>framework7 create --ui
√ All good, you have latest framework7-cli version.
√ Launching Framework7 UI server

Framework7 CLI UI is running on http://localhost:3001 (CTRL + C to exit)

What could be the reason of this?
