Setup error thinks pythonpath is empty

I am trying to install the scikits.nufft package here. I am downloading the zip file, unpacking and cd into the directory. It contains the setup.py file, so I run

python setup.py install

but it gives me the following error related to my PYTHONPATH

 sudo python setup.py install sudo: unable to resolve host Lenovo /usr/local/lib/python2.7/dist-packages/distribute-0.6.31-py2.7.egg/setuptools/command/install_scripts.py:3: UserWarning: Module dap was already imported from None, but /usr/lib/python2.7/dist-packages is being added to sys.path from pkg_resources import Distribution, PathMetadata, ensure_directory running install Checking .pth file support in /usr/local/lib/python2.7/site-packages/ /usr/bin/python -E -c pass TEST FAILED: /usr/local/lib/python2.7/site-packages/ does NOT support .pth files error: bad install directory or PYTHONPATH You are attempting to install a package to a directory that is not on PYTHONPATH and which Python does not read ".pth" files from. The installation directory you specified (via --install-dir, --prefix, or the distutils default setting) was: /usr/local/lib/python2.7/site-packages/ and your PYTHONPATH environment variable currently contains: '' Here are some of your options for correcting the problem: * You can choose a different installation directory, ie, one that is on PYTHONPATH or supports .pth files * You can add the installation directory to the PYTHONPATH environment variable. (It must then also be on PYTHONPATH whenever you run Python and want to use the package(s) you are installing.) * You can set up the installation directory to support ".pth" files by using one of the approaches described here: http://packages.python.org/distribute/easy_install.html#custom-installation-locations Please make the appropriate changes for your system and try again.

It seems like the path is empty, but when I check my path I get

 echo $PYTHONPATH /usr/local/lib/python2.7/site-packages:/home/david/PYTHON

Does anyone know why this might seem empty? or any other ideas as to what might be wrong here. Thanks, Dave

After Aya's comment above, I found a similar resolved issue here and got it to run by adding

 Defaults env_keep += "PYTHONPATH"

to the sudoers file. Ta Dave

For people who want to avoid sudo and install as a local user:

 PYTHONPATH=~/local/lib/python2.7/site-packages/ python ./distribute_setup.py
