I'd really appreciate if `venv` could create environments without symlinks.Working on many Python projects, each one with different requirements, I prefer to keep everything I need in a single virtualenv directory, rather than two (one for the virtualenv and one for the built Python).So I'd like to have a --copies option that lets me force venv not to create symlinks. I can work on a patch if this issue is accepted.

New changesetffb01a6c0960 by Vinay Sajip in branch 'default':Closes#18807: pyvenv now takes a --copies argument allowing copies instead of symlinks even where symlinks are available and the default.http://hg.python.org/cpython/rev/ffb01a6c0960

Requesting re-open of this issue, using --closes to force no symlinks to be created still results in venv trying to create symlinks.I'm using Python 3.4 with the following command inside a vagrant Ubuntu 14.04 virtualbox image.  The folder is a SMB mount from a windows host, which does not allow symlinks.Expected behavior: os.symlink() is never called when you run:python3.4 -m venv --copiesActual behavior: os.symlink() is still called in a few places such as:http://hg.python.org/cpython/file/b8e4bb1e1090/Lib/venv/__init__.pyline: 147line: 215I have a fix for line 215 that I'm testing now (basically just need to call copier() instead of os.symlink()). I don't want to mess with line 147 due to it being OSX specific and I have no way to test it.  But in theory it should also just be a call to copier()

While you may be right about line 215, line 147 isn't analogous, because in the latter case it's a symlink to a directory. We don't really want the entire lib directory tree *copied* into lib64 (and in any case, the populating of lib will happen much after venv creatuion, when things are installed into the venv: a copy is of no use here).

Preliminary patch for line 215, per earlier description.While this doesn't appear to break anything and creates both copies and symlinks correctly, I do have these four failing unit tests:test_multiprocessing_fork test_multiprocessing_forkservertest_multiprocessing_main_handling test_multiprocessing_spawnI don't have time right now to look into it to see if they're related to my change (at first glance, it looks like not).

Ok cool, as you said line 215 then seems to be the only one that needs it.

I've made the change - not exactly the same as your patch, which was missing an os.chmod() and doing an unnecessary os.path.join() - but thanks for submitting a patch :-).However, note that on 64-bit Linux systems (actually any POSIX other than OS X) a symlink lib64 -> lib is still created. Perhaps this could be omitted, but I'm not sure if that would cause problems with pip. I've posted a note on the relevant issue -#21197.

The os.chmod() will fail if path is a symlink.  At the very least it must be guarded by a `not os.path.islink()` call like above it.  I'll add this check to 3.4 and 3.5.
