No idea what that means. The wart is that --help-commands is ever displayed in the first place, because it's a distutils command that easy_install doesn't support. In other words, --help-commands really isn't a valid option to easy_install; never was and never will be. However, it appears that there is distutils code that was added in Python 2.5 that displays it even when I'm trying to prevent it from doing so. (If you run easy_install for Python 2.3 or 2.4, the --help-commands option doesn't appear.) I'll look into suppressing the output from Python 2.5, especially since it lists additional options that don't make sense for easy_install.

Incompatibility issue with setuptools 0.6c7-py2.4 and workingenv-0.6.5-py2.4
by Lauri Hallila 08 Oct '07

08 Oct '07

Hello! I noticed a small problem in setuptools... workingenv (version 0.6.5-py2.4), in some instances, adds a comment-line "# Duplicating setuptools' site.py..." into the beginning of site.py (workingenv.py, line 1214). Problem is that easy_install.py checks if the existing file site.py starts with "def __boot():", and if it doesn't, it raises an error. I fixed the problem in my own environment by skipping empty and comment-lines in easy_install.py (fixed file attached). I just thought to inform you of the problem... feel free to take my fix into setuptools if you like my way to fix the problem. Best regards, Lauri Hallila

--help-commands option to easy_install not working
by The Cadet 07 Oct '07

07 Oct '07

Hi, I wanted to get more help on the command line for ``easy_install`` commands. Running ``easy_install --help`` tells me:: Common commands: (see '--help-commands' for more) but the ``--help-commands`` option does not seem to work:: $ easy_install --help-commands usage: easy_install [options] requirement_or_url ... or: easy_install --help error: option --help-commands not recognized I'm using ``setuptools-0.6c7-py2.5.egg``. Is this something that's already been fixed? I checked the docs at http://peak.telecommunity.com/DevCenter/EasyInstall , but the only mention of ``--help-commands`` was in the 0.6a10 section where it said "Fixed the annoying --help-commands wart.". No idea what that means. Thanks.

What's appears to be wrong is that you have (or had) more than one Python installation, and I suspect the one you uninstalled was not the one that you were using. > I don't know. >I guess I'll post this to the c.l.py group too. I wouldn't bother until you find out what other Python(s) are installed on your system and get clear about which ones you're running. I tried installing PyCrypto from the same page you spoke of, and it worked fine for me using Python 2.4 on Windows.

I don't suppose that could be the problem, could it? Since I don't know what pythons you've been running for what, I have no idea.

I did as you said and now I'm back to the >first error I posted. I deleted the distutils-egg and the >setuptools-egg directories. Try this: python -c "import distutils; print distutils.__version__, distutils.__file__" This should print a version and a filename. The filename should be something like 'c:\Python24\Lib\distutils\...' (*without* site-packages between the Lib and distutils), and the version should be 1.0.3 or higher. If the location is different, you haven't uninstalled it correctly. If the location is correct but the version is less than 1.0.3, you installed the distutils over the version that came with Python, and will have to reinstall Python to fix it.

The current version of distutils is already included with every version of Python; you just installed a broken out-of-date version of them. Delete what you installed (presumably a distutils-*.egg file or directory), and your system should work again.

bdist_wininst TypeError

Hi, I was typing out the distutils package this morning and hit a wall within a few minutes of running it. I got it using the "Easy Install" script found here: http://peak.telecommunity.com/DevCenter/EasyInstall#installing-easy-install To test the package, I tried using it on PyCrypto, found here: http://www.amk.ca/python/code/crypto.html After unzipping that package to a temporary directory, I ran distutils from the command line as follows: L:\Temp\pycrypto-2.0.1>python setup.py bdist_wininst Here's the traceback that gave me: L:\Temp\pycrypto-2.0.1>python setup.py bdist_wininst running bdist_wininst running build running build_py running build_ext Traceback (most recent call last): File "setup.py", line 164, in ? core.setup(**kw) File "L:\Python24\lib\distutils\core.py", line 149, in setup dist.run_commands() File "L:\Python24\lib\distutils\dist.py", line 946, in run_commands self.run_command(cmd) File "L:\Python24\lib\distutils\dist.py", line 966, in run_command cmd_obj.run() File "l:\python24\lib\site-packages\setuptools-0.6c7-py2.4.egg\setuptools\comm and\bdist_wininst.py", line 37, in run _bdist_wininst.run(self) File "L:\Python24\lib\distutils\command\bdist_wininst.py", line 107, in run self.run_command('build') File "L:\Python24\lib\distutils\cmd.py", line 333, in run_command self.distribution.run_command(command) File "L:\Python24\lib\distutils\dist.py", line 966, in run_command cmd_obj.run() File "L:\Python24\lib\distutils\command\build.py", line 112, in run self.run_command(cmd_name) File "L:\Python24\lib\distutils\cmd.py", line 333, in run_command self.distribution.run_command(command) File "L:\Python24\lib\distutils\dist.py", line 966, in run_command cmd_obj.run() File "L:\Python24\lib\distutils\command\build_ext.py", line 279, in run self.build_extensions() File "setup.py", line 117, in build_extensions build_ext.build_extensions(self) File "L:\Python24\lib\distutils\command\build_ext.py", line 402, in build_exte nsions self.check_extensions_list(self.extensions) File "L:\Python24\lib\distutils\command\build_ext.py", line 304, in check_exte nsions_list (ext_name, build_info) = ext TypeError: unpack non-sequence The only information I can find about this is an ongoing dispute about some Pyrex version causing this issue: http://mail.python.org/pipermail/distutils-sig/2007-September/008211.html I am using Python 2.4, NOT Pyrex.

patches: ez_setup.py: don't import setuptools into your current address space in order to learn its version number
by zooko 05 Oct '07

05 Oct '07

Folks: We're gradually converting the allmydata.org tahoe project [1] and its spin-off packages to use setuptools. One problem that comes up is that ez_setup.py might require a newer version of setuptools than the version of setuptools already installed. For example, although Tahoe currently uses setuptools to manage its dependencies on zfec, foolscap, and nevow [2], but if we execute simplejson's ez_setup.py then it requires setuptools v0.6c7 and refuses to proceed if an earlier version is installed. One solution for this problem could be for the packager of simplejson (Bob Ippolito) to use the "min_version" patch that we contributed to ez_setup.py [3]. This is assuming that simplejson doesn't actually *require* the latest version of setuptools, and we could successfully install with a slightly older version, but what if a package actually does require a newer version of setuptools than the one that is already installed? The following patch was created by Tahoe contributor Arno Washck and then modified by me in order to get around such a problem. The idea is simple enough -- reload setuptools. There may be some subtleties that we still need to work out. This patch hasn't been tested in its current form. --- ez_setup.py~ 2007-09-10 12:36:30.000000000 -0600 +++ ez_setup.py 2007-09-18 15:15:23.000000000 -0600 @@ -95,13 +95,9 @@ pkg_resources.require("setuptools>="+version) except pkg_resources.VersionConflict, e: - # XXX could we install in a subprocess here? - print >>sys.stderr, ( - "The required version of setuptools (>=%s) is not available, and\n" - "can't be installed while this script is running.
