Undefined method "sum"

[leduyquang753]

Hi! In my local TNoodle repository, when I ran ./tmt i18n check which uses the wca-i18n gem, the following error appeared:

leduyquang753@QuangPC:~/TNoodle$ ./tmt i18n check

What I was doing wrong???

Ah, it looks like Array#sum was introduced in Ruby 2.4 and you are using Ruby 2.3. See https://blog.bigbinary.com/2016/11/02/ruby-2-4-introduces-enumerable-sum.html.

I've fixed this by changing the gem to require ruby >= 2.4. I'll update TNoodle to use the latest release of this gem.
