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

2013-01-29 Thread Nicholas Kolatsis
Thanks. I've gotten everything working now.

For anyone else who comes along, 'sudo apt-get install python-dev' did the job.

 
 Note that Fabric is useful for much, MUCH more than this.
 

I look forward to finding out :)

 
 Off-topic: why is your virtualenv/project name so weird?
 

Noted. It's the naming pattern that I use for my projects. I should use 
something better but I'm using this because I usually restart something several 
times before I'm happy with it. I was reading up on branching with git earlier. 
It looks like that will put an end to this bad practice.

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

2013-01-28 Thread 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.
