easy-install

I have a python library. Unfortunately I have not updated it to work with python 3 yet. in its setup.py, I added install_requires=['python<3'], My intent was to not allow this package to be installed / used under python 3, because I know it doesn't (yet) work. I don't think this is the right way to do it, because pip then tries to download and install python 2.7.3 (which is already the installed version!). How should I specify my library dependency on a particular range of python interpreter versions? Should I add a Programming Language :: Python :: 2 :: Only tag? Will this actually prevent

I have a Mac running Python 2.6. When I try to use easy_install I get this message: /usr/bin/easy_install-2.6:7: UserWarning: Module pkg_resources was already imported from /System/Library/Frameworks/Python.framework/Versions/2.6/Extras/lib/python/pkg_resources.pyc, but /Library/Python/2.6/site-packages is being added to sys.path from pkg_resources import load_entry_point /usr/bin/easy_install-2.6:7: UserWarning: Module site was already imported from /System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site.pyc, but /Library/Python/2.6/site-packages is being added to sys.path

python setup.py install will automatically install packages listed in requires=[] using easy_install . How do I get it to use pip instead? Colonel Panic Yes you can. You can install a package from a tarball or a folder, on the web or your computer. For example: Install from tarball on web pip install https://pypi.python.org/packages/source/r/requests/requests-2.3.0.tar.gz Install from local tarball wget https://pypi.python.org/packages/source/r/requests/requests-2.3.0.tar.gz pip install requests-2.3.0.tar.gz Install from local folder tar -zxvf requests-2.3.0.tar.gz cd requests-2.3.0 pip

I use this command in the shell to install PIL: easy_install PIL then I run python and type this: import PIL . But I get this error: Traceback (most recent call last): File "<console>", line 1, in <module> ImportError: No module named PIL I've never had such problem, what do you think? On some installs of PIL, You must do import Image instead of import PIL (PIL is in fact not always imported this way). Since import Image works for you, this means that you have in fact installed PIL. Having a different name for the library and the Python module is unusual, but this is what was chosen for (some

I have dependency_links in my setup.py: ... dependency_links = ['http://github.com/robot-republic/python-s3/tarball/master.tar.gz#egg=python-s3'], ... But it doesn't work. However install_requires works fine. Maybe there are another method to set up git repo as required for setup.py? Laur Ivan This answer should help. In a nutshell, you need to specify the version (or "dev") for the #egg=python-s3 so it looks like #egg=python-s3-1.0.0 . Updates based on @Cerin's comment: Pip 1.5.x has a flag to enable dependency-links processing: --process-dependency-links . I haven't tested it because I agree

I have a difficult time using pip to install almost anything. I'm new to coding, so I thought maybe this is something I've been doing wrong and have opted out to easy_install to get most of what I needed done, which has generally worked. However, now I'm trying to download the nltk library, and neither is getting the job done. I tried entering sudo pip install nltk but got the following response: /Library/Frameworks/Python.framework/Versions/2.7/bin/pip run on Sat May 4 00:15:38 2013 Downloading/unpacking nltk Getting page https://pypi.python.org/simple/nltk/ Could not fetch URL [need more
