I have issues installing pycrypto (and thus fabric) with pip

[Nicholas Kolatsis]

I'm not sure this is the right place for this but I'm don't know where else to put this.

I want to give fabric a try (as recommended here: http://www.jeffknupp.com/blog/2012/10/24/starting-a-django-14-project-the-right-way/). Installing fabric results in two dependencies (paramiko and pycrypto) being installed as well. All is dandy until it is time to install pycrypto.

A bit of searching reveals this in the documentation:

Package tools

We strongly recommend using pip to install Fabric as it is newer and generally better than easy_install. However, a combination of bugs in specific versions of Python, pip and PyCrypto can prevent installation of PyCrypto. Specifically:

    Python = 2.5.x
    PyCrypto >= 2.1 (which is required to run Fabric >= 1.3)
    pip < 0.8.1

When all three criteria are met, you may encounter No such file or directory IOErrors when trying to pip install Fabric or pip install PyCrypto.

The fix is simply to make sure at least one of the above criteria is not met, by doing the following (in order of preference):

    Upgrade to pip 0.8.1 or above, e.g. by running pip install -U pip.
    Upgrade to Python 2.6 or above.
    Downgrade to Fabric 1.2.x, which does not require PyCrypto >= 2.1, and install PyCrypto 2.0.1 (the oldest version on PyPI which works with Fabric 1.2.)

I've got pip and python covered above but I'm still unable to install fabric as shown below.
