I am using this weird SuSE machine. I need to install a python package in my python 2.7. I downloaded it from the site and then untar it and cd to the directory.. Tried:

cd /python-package_Pyxnat/
python2.7 setup.py install

I am getting following output:

/usr/lib/python2.7/distutils/dist.py:267: UserWarning: Unknown distribution option: 'install_requires'
  warnings.warn(msg)
/usr/lib/python2.7/distutils/dist.py:267: UserWarning: Unknown distribution option: 'summary'
  warnings.warn(msg)
running install
running build
running build_py
running install_lib
running install_egg_info
Removing /usr/local/lib/python2.7/site-packages/pyxnat-1.0.0.0-py2.7.egg-info
Writing /usr/local/lib/python2.7/site-packages/pyxnat-1.0.0.0-py2.7.egg-info

Error after importing pyxnat package:

>>> import pyxnat
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "pyxnat/__init__.py", line 13, in <module>
    from .core import Interface
  File "pyxnat/core/__init__.py", line 4, in <module>
    from .interfaces import Interface
  File "pyxnat/core/interfaces.py", line 8, in <module>
    import requests
ImportError: No module named requests

Why am I not able to import python package even after installing it?

  • Use a package manager. It used to be zypper for SUSE. Maybe it's now something else. – Faheem Mitha Jan 11 '16 at 15:45

You installed the package, but not its dependencies. That is something running python setup.py install will not do for you, you better try a package manager like pip in which case you don't have download pyxnat first:

pip install pyxnat

which will get you all dependencies specified for pyxnat, not just the requests packages. Alternatively you can do:

pip install -e .

in the untarred pyxnat directory.

If you don't have pip installed use your package manager to install (probably called python-pip) or use the instructions here.

I second @Digisec recommendation of using a virtualenv, especially if your python version is used by some system programs as well.

  • I totally forgot about dependencies. Removing my answer. – Digisec Jan 11 '16 at 15:39
