Yes, now it works! Thanks a lot! Last but not least, could you point me in the correct direction to add a patch for the distutils documentation, explaining this more clearly?

I basically follow the tutorial in the distutils docs, which is a little unclear to me in some points.

If I do as you say it looks like this:
--------------------------------------------------------------
  [...]
    package_dir = { '' : src_path },
    requires = [
        'pylibssh2==1.0.1',
        'pyserial==2.5'
    ],provides = [
        '{} ({})'.format(project, version)
    ]
  [...]
--------------------------------------------------------------
And the result of ``$ python setup.py sdist`` is:

    [...] # exception stack
    ValueError: expected parenthesized list: '==1.0.1'

That also happens if I add spaces between project name and comparator.

This is a common mistake. The parenthesis are a Metadata 1.2+ thing. Omit them for distutils.

Hi everybody,

I think I pretty much read all of the http://docs.python.org/2/distutils/ and started to create a pypi repository for my project (http://pypi.python.org/pypi/monk_tf). Now there are some things that are not so clear from the documentation, with the most important being requirement handling.

I have the same requirements written down in two ways:
 a) a requirements.txt file, which can be called with pip install -r requirements.txt. Yet I don't see any user downloading a requirements.txt file from somewhere, then installing it and only then afterwards getting started with actually installing the package they want to install. Who would do that?

 b) requires attribute in the setup function call in setup.py. For some reason pip completely seems to ignore it. I tested the following way (come along with the code from https://github.com/DFE/MONK, if you like):

    $ cd MONK
    $ python setup.py sdist
    $ cd dist
    $ tar xfvz monk_tf-v0.1.1.tar.gz
    $ cd monk_tf-v0.1.1
    $ python setup.py install
    running install
    running build
    running build_py
    running install_lib
    running install_egg_info
    Writing /usr/local/lib/python2.7/dist-packages/monk_tf-v0.1.1.egg-info
    $python
    >> import monk_tf
    (Exception, because a required package can't be found)

So this also didn't seem to install any of the required packages.

I'd really like to know, what I am doing wrong here. Anybody ideas or suggestions? Is there another way to tell distutils about the packages that should be installed before my package is installed?

Cheers
Erik

Generally requires.txt is for specific versions of dependencies and the setup.py list is more permissive.

Try using pip to install your sdist instead of running setup.py directly.


Hi Daniel,

I also tried ``pip install monk_tf-v0.1.1.tar.gz``, with the same result as using setup.py directly. He installs it but doesn't consider the "requires" list.
From your mail I would interprete that distutils actually should consider the required packages? Maybe I just wrote something incorrectly.
Does the following look like a correct statements of the requires parameter?
--------------------------------------------------------------
  [...]
    package_dir = { '' : src_path },
    requires = [
        'pylibssh2 (==1.0.1)',
        'pyserial (==2.5)'
    ],provides = [
        '{} ({})'.format(project, version)
    ]
  [...]
--------------------------------------------------------------

Cheers
Erik
