How to create a temporary virtualenv

[caioariede]

Temporary virtualenvs can be useful in some situations:

• Try out a new library or its new version - once installed, run a Python shell and play with it
• Use a Python command-line tool that you don't want to keep installed for long

With dpv it is trivial:

# create a temporary virtualenv
dpv --temp

# install some lib you want to test
pip install cowsay

# try it!
# some shells may require you to run `rehash` first
cowsay hello dpv
  _________
| hello dpv |
  =========
         \
          \
            ^__^
            (oo)\_______
            (__)\       )\/\
                ||----w |
                ||     ||

You can now exit with CTRL-D and your virtualenv will soon be discarded
