I always seem to forget how to setup a virtualenv for python 3 - with my move to a new laptop using linux I had to do this again so I kept the setup here for future reference. It's simple but easy to forget if you only ever do it, say, once every year or so.
The following will result in a virtualenv in the directory ~/venv/py-3.4 using the executable /usr/bin/python3.4:
$ sudo pip install virtualenv [sudo] password for sean: Downloading/unpacking virtualenv Downloading virtualenv-14.0.6-py2.py3-none-any.whl (1.8MB): 1.8MB downloaded Installing collected packages: virtualenv Successfully installed virtualenv Cleaning up... $ mkdir ~/venv $ virtualenv -p /usr/bin/python3.4 ~/venv/py-3.4 Running virtualenv with interpreter /usr/bin/python3.4 Using base prefix '/usr' New python executable in /home/sean/venv/py-3.4/bin/python3.4 Also creating executable in /home/sean/venv/py-3.4/bin/python Installing setuptools, pip, wheel...done. $ python --version Python 2.7.9 $ source ~/venv/py-3.4/bin/activate (py-3.4) [sean@seoul ~]$ python --version Python 3.4.2
I'm trying to stick to one-post-per-week but the last month been pretty busy for me so I've exhausted of scheduled posts that I built up. I have about 3-4 interesting things in the pipeline which will pop up over the next month, so I think I can get away with publishing something simple like this for one week :)
