    My Ubuntu 10.04 came with Python 2.6. Now, I also installed Python 2.7, which is the system default now because when I start python from the terminal, it starts python 2.7.

    Now, I want to install the library pysftp using pip, but I'm having a hard time doing so. Below follow some results of my attempts and conclusions. I did pip install pysftp, but it says the following:

    Downloading/unpacking pysftp
    Running setup.py egg_info for package pysftp
    Traceback (most recent call last):
    File "<string>", line 3, in <module>

    packaging = pkg_resources.packaging
    AttributeError: 'module' object has no attribute 'packaging'
    Complete output from command python setup.py egg_info:

    It seems to me that pip (which was obviously installed before Python 2.7 was installed) links to the old version of Python, which doesn't support pysftp. Also because when I do pip --version it says:

    pip 0.3.1 from /usr/lib/python2.6/dist-packages (python 2.6)


    When I do whereis python, it gives me the following information:

    python: /usr/src/Python-2.7.10/python /usr/bin/python2.6 /usr/bin/python /etc/python2.6 /etc/python /usr/lib/python2.6 /usr/lib/python3.1 /usr/lib64/python2.6 /usr/lib64/python3.1 /usr/local/bin/python2.7-config /usr/local/bin/python /usr/local/bin/python2.7 /usr/local/lib/python2.6 /usr/local/lib/python2.7 /usr/include/python2.6 /usr/share/python /usr/share/man/man1/python.1.gz


    How can I install pysftp?
