Answer 1

It might be already late but, but I had also this problem with the commands.

I use: ./node_modules/.bin/ng-xi18n -p src/tsconfig.json --i18nFormat=xlf or to make it short I added this line "i18n": "ng-xi18n -p src/tsconfig.json --i18nFormat=xlf" to my package.json "scripts" and then I can simply run npm run i18n .

Also the command ng xi18n --output-path=src/locale works for me

Refer to this post as it has good answers and I got it working following it: Angular2 and webpack - i18n plugin vs ng2-translate
