Uninstall

Hi all, Someone asked me today, how to uninstall a package that was installed with easy_install. The best I could come up with was, remove the .egg file/directory from site-packages and remove the corresponding line from easy_install.pth. That's pretty lame and error prone. Is there a better way? Martin -- Acquisition is a jealous mistress

Bundling ez_setup only affects source installs.

[setuptools]: Installing deps
by james.mills＠au.pwc.com 24 Aug '07

24 Aug '07

Hi all, I've followed the documentation for setuptools with regards to installing dependencies and installing setuptools (if it's not instlaled, or upgrading it). I can't however get any of these features of setuptools to work correctly. 1. setuptools is not being installed when users install the application's installer 2. required dependencies arenot being installed either. This is being done on Windows XP machine with Python-2.5.1 I do have ez_setup.py in the same directory as setup.py of the project in question and have the following 2 lines at the top of setup.py: import ez_setup ez_setup.use_setuptools() In my setup.py I have: install_requires = [ "pymills" ], However this is not being installed when the app's installer is run. Also setuptools is not being installed either. Am I missing something ? From what I've read this should _all_ work :) cheers James James Mills PricewaterhouseCoopers Australia Office: +61 (7) 3257 8847 Mobile: 0430 165 904 Fax: +61 (7) 3023 0938 james.mills(a)au.pwc.com http://www.pwc.com/au Please consider the environment before printing this email _________________________________________________________________ Please consider the environment before printing this email.

I've fixed it in SVN; you can "easy_install setuptools==dev06" to get the fixed version.

easy_install doesn't handle extras properly
by Jim Fulton 22 Aug '07

22 Aug '07

Suppose I have a package x that defines an extra y in version 2. In version 3, I remove the extra. Now, if I use easy_install to request x with extra y. easy_install will get the newest x, version 3, and complain that it has no extra y: (env25)jim@ds9:~/tmp$ easy_install -f /home/jim/tmp/x/dist 'x[y]' Searching for x[y] Best match: x 3 Processing x-3-py2.5.egg creating /home/jim/tmp/env25/lib/python2.5/x-3-py2.5.egg Extracting x-3-py2.5.egg to /home/jim/tmp/env25/lib/python2.5 Adding x 3 to easy-install.pth file Installed /home/jim/tmp/env25/lib/python2.5/x-3-py2.5.egg Processing dependencies for x[y] Traceback (most recent call last): ... pkg_resources.UnknownExtra: x 3 has no such extra feature 'y' If I tell easy_install to install a version < 3, then it gets version 2, which has the extra: (env25)jim@ds9:~/tmp$ easy_install -f /home/jim/tmp/x/dist 'x[y] <3' Searching for x[y]<3 Best match: x 2 Processing x-2-py2.5.egg ... Finished installing x[y]<3 easy_install is supposed to get the best distribution that satisfies a requirement, but it doesn't handle the extra part of the requirement. This is just another example of the burden of supporting the feature. Can we *please* get rid of the extras feature. It has some benefit, but I really don't think the benefit justifies the extra complexity in the model or the burden on tool developers. Jim -- Jim Fulton mailto:jim@zope.com Python Powered!

Declaring conflicts
by Thomas Lotze 22 Aug '07

22 Aug '07

What's the recommended practice, if any, for declaring conflicts between egg distributions? The use case I have in mind is changing dependencies between packages A and B: * A-1 depends on B-1, but not the other way around, * I want to make B-2 depend on A-2, but not the other way around, * and I want to make sure that if someone has A-1 and B-1 installed, they cannot upgrade only A, because A-2 and B-1 conflict in terms of functionality. AFAICS, nothing prevents people from upgrading only A if only dependencies, but no conflicts are declared. I didn't find any documented way of declaring conflicts, though. -- Thomas

I finally got the kiva rpm to build using bdist_rpm
by Stanley A. Klein 21 Aug '07

21 Aug '07

I finally got the kiva rpm to build. I also got the docs and examples into the proper doc directory. Here is what it took: First, run "python setup.py bdist_rpm", which will fail with a list of installed but unpackaged files. Somehow the full set of installed files isn't being recorded, probably because of some problem among numpy distutils, python distutils, setuptools, and Fedora rpm brp-python-bytecompile that isn't solved by the [install] optimize=1 option in setup.cfg (that works in most cases). Then create a file (I called it problem_files) with a list of the installed but unpackaged files. Also, create a new install script to be put into the rpm spec file that appends the problem file list to INSTALLED_FILES (where the installed files are recorded in the default spec file). Then run the setup with options that use the new install script. The rpm packaging of the docs files is just another option to the setup run. Below are the relevant scripts and files. I think I may still have a problem with the enthought namespace __init__.py and the nspkg.pth file that will presumably be fixed in an upcoming version of setuptools. BTW, I don't know what effect this has, but there are also __init__.pyc and __init__.pyo files packaged into the rpm with the namespace file. IIRC it may not be supposed to be there, but it got in somehow, probably because of the same problem that caused the installed files to be incorrectly recorded.

Buildout now uses the simple index.
by Jim Fulton 21 Aug '07

21 Aug '07

As of yesterday's zc.buildout release, buildout now uses the simple package index: http://cheeseshop.python.org/simple by default. (You can cause it to use another index by setting the buildout index option.) This change should provide significantly better performance and will make it easier to use historical releases, because the simple interfaces shows releases that have been hidden from the human interface. It would be nice if easy_install also used the simple interface. Jim -- Jim Fulton mailto:jim@zope.com Python Powered!

Heads up: major change in zc.buildout policy for selecting distributions
by Jim Fulton 20 Aug '07

20 Aug '07

I'm about to make a new release of zc.buildout that uses a different policy for selecting distributions. In particular, by default, zc.buildout will now prefer final distributions over non-final ones. If there are final and non-final distributions that satisfy a requirement, buildout will, by default, select a final distribution even if there are non-final distributions that satisfy a requirement. This release will cause many existing buildouts to use older distributions than they do now. You can change this behavior by providing a prefer-final buildout option: [buildout] prefer-final = false Jim -- Jim Fulton mailto:jim@zope.com Python Powered!
