multipip
pip utility refuses to handle multiple requirements for one package:
$ pip install 'nose>=1.2' 'nose>=2' 'nose<4'
Double requirement given: nose>=2 (already in nose>=1.2, name='nose')
Use multipip to join these requirements:
$ multipip 'nose>=1.2' 'nose>=2' 'nose<4'
nose>=2,<4
Files of requirements can be used as well:
$ cat pip-requires
nose<4
$ multipip 'nose>=1.2' 'nose>=2' -r pip-requires
nose>=2,<4
multipip prints error messages for incompatible requirements to stderr and chooses the first one:
$ cat pip-requires
pip==1.3
$ multipip 'pip==1.2' -r pip-requires
pip: incompatible requirements
Choosing:
command line: pip==1.2
Conflicting:
-r pip-requires (line 1): pip==1.3
pip==1.2
It is possible to filter some packages from printed output. This can be useful for a huge pip-requires file:
$ cat pip-requires
nose<4
pip==1.2
nose>=1.2
$ multipip -r pip-requires --ignore-packages nose
pip==1.2
Installed packages can be filtered, too (they are taken from pip freeze):
$ cat pip-requires
nose<4
pip==1.2
nose>=1.2
$ pip freeze | grep nose
nose==1.1.2
$ multipip -r pip-requires --ignore-installed
pip==1.2
py2rpm
Distutils provides an interface for building RPMs:
$ python ./setup.py bdist_rpm
This tool has several problems: * Red Hat based distros use different package names, e.g., python-setuptools instead of distribute, python-nose instead of nose and so on; * Requires and Conflicts sections for generated RPM are incorrect; * sometimes not all required files are packaged; * miscellaneous problems with man files; * package directory in /usr/lib*/python*/site-packages/<pkg> is not owned by any RPM; * some packages (like selenium) are architecture dependent but bdist_rpm generates BuildArch: noarch for them.
py2rpm is aimed to solve all these problems.
py2rpm accepts a list of archive names or package directories and builds RPMs (current directory is used by default):
$ py2rpm
