#  Please be noticed that the virtual environment directory was set to ~/.pyvenv
#  you might want to change it.
#  I use only python3, no suffix was added to the directory.
#  If you need to use both 2 & 3, it would be better to create 2 virtual environment directories.

# initiate a virtual environment
pyvenv-3.3 ~/.pyvenv

# add settings to .bashrc
PYTHONPATH=~.pyvenv/lib/python3.3/site-packages
export PYTHONPATH

# get and install setuptools, for a copy of easy_install
wget https://bootstrap.pypa.io/ez_setup.py -O - | python3 - --user

# get and install pip
wget https://bootstrap.pypa.io/get-pip.py -O - | python3 - --user

# give direction to the pip:
# you might want to add these lines to .bashrc
PATH=~/.local/bin/:$PATH
export PATH
# or, to add an alias, just save some keystroke for 'install'
alias pipu='~/.local/bin/pip3 install --user'
