I'm trying to perform web scraping with BS4 and then do some algebra work with the results in Sage 6.2 (in Lion 10.7.5). I assumed that /Applications/Sage-6.2.app/Contents/Resources/sage/sage -i beautifulsoup4 would work, but the result is

Next, I tried /Applications/Sage-6.2.app/Contents/Resources/sage/sage -sh <<< "easy_install --verbose pip" to get bs4 via pip. That succeeded; however /Applications/Sage-6.2.app/Contents/Resources/sage/local/bin/pip2.7 install beautifulsoup4 failed with error message

Next, I tried upgrading to Sage 6.6. That went smoothly, as did the installation of bs4. However, when I opened the notebook, I was unable to run code cells, because the "Shift-Enter" command only registered as "Enter" and gave me a new line instead of evaluating the code. Additionally, there was no "evaluate" button. Any recommendations to solve any of these issues would be greatly appreciated.
Unfortunately, Sage has changed how it handles optional packages like BS so that older versions may not be able to use them. You can always go to a mirror, though, like http://mirrors.mit.edu/sage/spkg/optional/ download it, and put it in your (old Sage's) optional spkg directory and try doing sage -i path/to/file.
As to the notebook issue, that should be a matter of doing a "hard cache reset" in the browser due to different jQuery versions, see e.g. here.

On Windows, no additional modules are needed.
On Mac, this module makes use of the pbcopy and pbpaste commands, which should come with the os.
On Linux, this module makes use of the xclip or xsel commands, which should come with the os. Otherwise run “sudo apt-get install xclip” or “sudo apt-get install xsel” (Note: xsel does not always seem to work.)
Otherwise on Linux, you will need the gtk or PyQt4 modules installed.
I hope this help. :)
I am trying to install a software called grizli (https://github.com/gbrammer/grizli/) in a conda environment.

pip install git+https://github.com/gbrammer/drizzle.git
resulting in

RecursionError: maximum recursion depth exceeded while calling a Python object
----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-req-build-ncjb9u8_/
The three points in the code stand for the repetition of the three lines that always appear in the same order and probably cause the RecursionError.
I have already tried different pip versions but it didn't change anything. Does anybody have an idea?
I just got the same issue. The only solution that worked for me was to downgrade sphinx to a version <=1.5.6 as mentioned here: https://github.com/ericmandel/pyds9/issues/53 (note that I already had astro-helpers >=2.0 when I got the issue, so the solution is on downgrading sphinx)
Just do: pip install sphinx==1.5.6
and then hopefully drizzle will install correctly.
I just installed Python 2.7.5 on my Windows 10 machine and I also got pip installed through setuptools. However whenever I try to install something using pip e.g. pip install numpy, I get this error message:

Since I'm pretty new to Python, I don't really understand what this error means. Any workaround?
I had a similar issue with a library that is using regular expressions (with the re.compile() function). I solved this issue installing the last version available 2.7.13 (I run a Windows 7).
Before I had the 2.7.6 version. I updated it installing the new version with the .msi installer, available in the Python web page.
I'm fairly new to Python, and Nitrous.IO, and MongoDB, and command line in general so would appreciate a little guidance here if possible.
I'm trying to install pymongo on my Nitrous.IO box but can't seem to find a way to do it - this tutorial suggests 'import pymongo' but that didn't work (see below).
I can't seem to find any tutorials or help on this - a google search for "install +pymongo with nitrous.io" gave me 0 results.

Does anyone know how I would go about installing this? It's starting to be a real pain!
You might be able to install it withpip using this advice. Once you've done that, you would use the import pymongo at the top of your code file.
I was giving a look at the "Learn Python The Hard Way" tutorial and when it told me to try it out by typing Python in Powershell after I installed it just kept giving me this:

I also tried running through the command prompt and got the same error. I've installed and uninstalled python about 3 times and have done a few reboots to no avail. I am very new to python and I'm confused on what to do here. I would also appreciate any links to other python tutorials.
In this case, from my understanding, you have no modules called "MAXREPEAT" or you(or the installer) have installed it somewhere wrong. A reinstallation or redirecting the path should get it to work.
