Switching Ruby and Python Versions
scoop reset
If you need to run multiple versions of Ruby or Python on the same computer, you can use scoop reset to switch between versions.
If you're familiar with rbenv or RVM this is roughly similar, although with scoop reset you always need to switch version manually.
Example
scoop bucket add versions # add the 'versions' bucket if you haven't already
scoop install ruby ruby19
ruby --version # -> ruby 1.9.3p551 (2014-11-13) [i386-mingw32]
# switch to ruby 2.x
scoop reset ruby
ruby --version # -> ruby 2.3.3p222 (2016-11-21 revision 56859) [x64-mingw32]
# switch back to 1.9.x
scoop reset ruby19
ruby --version # -> ruby 1.9.3p551 (2014-11-13) [i386-mingw32]
scoop reset re-installs shims for the app and updates environment variables according to the app manifest.
You can switch between Ruby versions as many times as you like—both versions remain installed but one takes priority.
Python
The same thing works for Python
scoop bucket add versions # add the 'versions' bucket if you haven't already
scoop install python27 python
python --version # -> Python 3.6.2
# switch to python 2.7.x
scoop reset python27
python --version # -> Python 2.7.13
# switch back (to 3.x)
scoop reset python
python --version # -> Python 3.6.2
