There are two cases:

1. You are using system wide packages and these are used by other 
packages and programs. But you cannot modify them as standard user.

2. You are creating your own local dedicated virtual environment that 
you can control as standard user, including installing additional 
packages that are not system wide.

The later is better because you control what you have and what version 
with no impact on system wide configuration and system configuration 
does not impact you either. This is especially important when you host 
your solution on a server where you have no administrative access. This 
is very common nowadays for web application hosting that use JavaScript, 
Ruby, Python, etc. You assume some system wide starting point like basic 
interpreter and web server, then you bootstrap your own local virtual 
environment to make bigger things work on your local account. Another 
good example here is the Automated Testing and CI (Continuous 
Integration) where build/testing scripts can bootstrap several local 
dedicated environments with a bit of different setup to test different 
components version impact, test regressions, etc :-)

Best regards :-)
