I don&#x27;t think virtualenv would solve their problems here; they are installing their agent on a customer&#x27;s machine. I imagine they didn&#x27;t want to ship the entire Python interpreter or alternatively install whatever version they want to use on the customer&#x27;s machine.<p>But you&#x27;re right, I don&#x27;t think Lua is unique in being able to fix this issue. I think it&#x27;s more that the author was already very good with it and liked it.
