Ruby Regex - Match words which begin with #

Question

So far I have

def get_hashtags(post)
  words = post.scan(/\#(\w+)/)
end

Which works, however it also gets words like "in#line" whereas I only want words which are beginning with #.

I have tried using \\b but I can't seem to get it right.

Any help would be much appreciated.

Thanks!

我会在＃之前使用空白边界

/(?<!\\S)\\#(\\w+)/
