Marten Lehmann added the comment: Could you please tell me, in which exact release or commit this is resolved? I'm using Python 3.3.0 on Ubuntu Precise and I noticed like the others, that e.g. easy_install and pip are installed to venv/local/bin instead of venv/bin and the site-packages folder being used is venv/local/lib/python3.3/dist-packages instead of venv/lib/python3.3/site-packages. Are both issues solved in experimental? So far I only saw a symlink-patch for virtualenv but that doesn't actually fix the problem of being double-local (venv and local-folder within venv), neither dist-packages: https://github.com/pypa/virtualenv/commit/285679cfd326c918676e765e06ed142db66efde0 -- nosy: +marten ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16480 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue16480] pyvenv 3.3 fails to create symlinks for virtualenv/local/{bin, lib} to virtualenv/{bin, lib}
Matthias Klose added the comment: having the posix_prefix as the default in Debian is an oversight on my side. it always should be posix_local. I'll fix this at least for 3.3 in current development releases. The rationale for this is that distutils based installs install by default into the path which is used by the distributor and get in conflict with the packages distributed by Debian/Ubuntu. At one of the language summits in Chicago I asked that the default installation target should be changed to the user dir, but this idea was rejected. Therefore you do have two site directories, called /usr/lib/pythonX.Y/dist-packages /usr/local/lib/pythonX.Y/dist-packages The renaming from site to dist was done to not conflict with a default python installation (without any configure parameters). The default install should go to /usr/local, packagers for Debian usually should use the Debian local distutils option --install-layout=deb. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16480 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Vinay Sajip added the comment: Even when posix_local becomes the default scheme on Debian python builds, it's not clear whether the suggested fix is the correct one to make, unless posix_local is added to sysconfig's list of _INSTALL_SCHEMES. Matthias comment makes sense when considering system-wide installs, but when installing into a venv, these considerations don't seem to apply. Technically the change is not hard to do, but I'm a little uncomfortable whether it's the right thing to do, as it's only for a specific Linux distribution, and it seems a bit of a kludge. Although the ideal situation is for software not to care whether it's running in a venv, I'm not sure whether installers like pip/distribute need to be completely ignorant of whether they're installing in a venv. For example, the posix_local scheme says that the site-packages directory is to be called 'dist-packages', which seems unnecessary in a venv since its purpose is really for system-wide installations. Yet, virtualenv names the directory 'site-packages', so it appears not to be following the scheme faithfully as far as that part of it is concerned. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16480 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Carl Meyer added the comment:
Here is the bug filed against virtualenv that led to the addition of the
local/ directory: https://github.com/pypa/virtualenv/issues/118
As Vinay pointed out, the original fix was later modified to be friendlier
to tools that dislike recursive symlinks.
I didn't used virtualenv but pyvenv-3.3, so if this is not a bug, my
question become:
how to proper install distribute and pip in python 3.3 venv since they
installs in VENV/local/bin and that VENV/bin/activate does not
include VENV/local/bin in $PATH ?

Marco Amadori added the comment: The question is: is this still necessary? Why exactly does posix_local need this, and does it need it for Python 3.3, 3.4 etc? Adding Carl to nosy, hoping he can shed some light on this. I hope to see the light on that too. ;-) Meanwhile, my problem was that after creating the virtualenv, as cited in the blog post above linked, I got stuck in installing pip (and thus distribute) in that virtualenv, because 'VENV/local/bin' is not in the $PATH (and it seems reasonable for a virtualenv that this will remain stable). So, (IMHO) if changing the $PATH is not a good idea, either python should do: 1. patch distribute and pip to do not install in ./local by default if in a VENV. (enviroment variable based?, whatever) 2. create the links after creating the VENV (my naïve solution) Am I right or I completely hit the wrong issue? -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16480 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue16480] pyvenv 3.3 fails to create symlinks for virtualenv/local/{bin, lib} to virtualenv/{bin, lib}
Vinay Sajip added the comment: as far as I know virtualenv does not create links for local/bin and friends either. AFAIK it never used to, but it seems to do so since 1.6.3, in an attempt to fix a problem with the posix_local install scheme. I just tested with virtualenv 1.6.4, and when I create a venv in /tmp/venv, it creates a symbolic link /tmp/venv/local which points back to /tmp/venv. This behaviour causes problems with e.g. PyCharm, which shows ever-nesting directories (turtles all the way down), has led to later versions of virtualenv creating an actual directory and symlinking the venv's contents to entries in it. The question is: is this still necessary? Why exactly does posix_local need this, and does it need it for Python 3.3, 3.4 etc?

New submission from Marco Amadori:
The solution to work around the bug is there:
http://ipoveraviancarriers.blogspot.it/2012/11/python-33-and-pyvenv-hackish-solution.html
But probably pyvenv should be patched in order to create symlinks.
Thanks!
