Why do we only talk about virtual environment in python? [duplicate]

Question

Why don't we talk about virtual environment in other programming language? Is there any equivalence for language like java, c++, javascript?

Is the concept in other language as important as in python? And I notice that the virtualenv was released initially in 2007. What did people use before that time? Or even before 2000?
