Hi,
I have a package "pywbem" which in its setup script specifies a number
of dependent packages via "install_requires".
I should also say that it extends setuptools/distutils with its own
additional keywords, e.g. it adds a "develop_requires", but I believe
(hope) that is irrelevant for my problem.
In pywbem 0.8.3, the dependencies are:
args = {
...,
'install_requires': [
'six',
'ply',
],
...,
}
and when running on Python 2.x, an additional one is added, dependent on
the OS platform and bit size:
if sys.version_info[0] == 2:
if platform.system() == 'Windows':
if platform.architecture()[0] == '64bit':
m2crypto_req = 'M2CryptoWin64>=0.21'
else:
m2crypto_req = 'M2CryptoWin32>=0.21'
else:
m2crypto_req = 'M2Crypto>=0.24'
args['install_requires'] += [
m2crypto_req,
]
The problem is that the pywbem package on PyPI does not show these
dependencies: https://pypi.python.org/pypi/pywbem/0.8.3
I wonder whether this is the reason for a particular installation
problem we have seen (https://github.com/pywbem/pywbem/issues/113).
I do see other projects on PyPI, that show the dependencies they specify
in their setup scripts, on their PyPI package page in a "*Requires
Distributions*" section:
* https://pypi.python.org/pypi/bandit/0.17.3
* https://pypi.python.org/pypi/json-spec/0.9.14
Many others also do not have their dependencies shown, including six,
pbr, PyYAML, lxml, to name just a few.
So far, I was unable to find out what the presence or absence of that
information is related to, in the source of the project.
Here are my questions:
1. What causes the "Requires Distributions" section on a PyPI package
page to show up there?
2. Is it important to show up there (e.g. for some tools)?
