Rubyist here; how does one install the BeautifulSoup module here (Macbook Pro with Mountain Lion)? ./ghrabber.py "path:.bash_history" File "./ghrabber.py", line 3, in <module> import BeautifulSoup ImportError: No module named BeautifulSoup I tried easy_install beautifulsoup but it gave a permissions error, so I ran it as sudo and that worked, but when I re-run the script it still throws the same error. Does python lack 'bundle install'-like functionality?

Try using pip. You can install it with "easy_install pip" and then run "pip install beautifulsoup".

pip install beautifulsoup You might have to install pip with easy_install

  Thanks! With Python, do you have to manually install each module and keep track of the versions?

    If you are using pip you can type "pip freeze" and it will spit out a list of all modules and the version currently installed. Most write this out to a file called "requirements.txt" in their project root. You can then use this list to install modules via "pip install -r requirements.txt" Same functionality as bundle install, just pythonic.

      What s/he said. Although keeping track of new updates is a bit of a pain, since there isn't a service like the one Rubyists have to get information about new gem versions. Pythonistas will have to use something like pip-tools < https://github.com/nvie/pip-tools https://github.com/nvie/pip-tools >, as far as I can tell.

        Nice, I hadn't seen pip-tools before. There is also yolk (pip install yolk) that will list available updates.

    I'm not very familiar with Ruby, but I know there are some similar pain-points wrt packages/dependencies and maintaining "pristine" (aka "actually working") project trees (it's not specific to python/ruby either - hence package managers like apt/yum, build tools like apache maven etc). What I usually do, is I have a system python for packages managed with apt (There are a lot of these, try): aptitude search '?and(?depends(python),?installed)' - and a system installed virtualenv. I then have a local python virtulalenv for installing misc packages (eg: a more recent mercurial than the one distributed in apt on older Debian distros): virtualenv ~/opt/python-misc ln -s ~/opt/python-misc/bin ~/pybin # In .bashrc: if [ -d "~/opt/pybin" ] then PATH="~/opt/pybin:${PATH}" fi; export PATH Note my "local" python virtualenv is before system in path, so any casual pip install "shiny-package-that-migh-break-system" just (at worst) means I have to recreate the virtualenv (or pip uninstall it). But for projects -- I highly recommend looking at buildout.
