Magento 2 - Braintree Payment Method not working

[parekhreena]

I have enabled Braintree payment method from Stores > Configuration > Payment Methods. I cleared var/cache, var/page_cache and var/generation and tried to place a normal order with braintree, but checkout page appears blank after braintree is enabled. In my console i get following error:

TypeError: value is undefined
return value.length <= +params;
/pub/static/frontend/Magento/luma/en_US/Magento_Ui/js/lib/validation/rules.js

So, I cleared pub/static, var/view_preprocessed and ran the command php bin/magento setup:static-content:deploy then i ran the checkout Page URL again, but I am getting same error. I am facing this error on Ubuntu. I also checked on another Linux Mint system, in that I followed same process but Braintree is not appearing in Payment Methods list, even when it is correctly configured from backend. I am checking Braintree Sandbox Mode.

Looks like its a php version issue, issue already posted check #3797. Roll back to php 5.6 and re-test, that should help in the short term.
