Installation error

edit

Hello again
I tried to install Askbot again on a fresh Ubuntu 14.04 LTS following this list of commands:

sudo su
mkdir /var/www/html/askbot-devel  
cd /var/www/html/askbot-devel  
git clone git://github.com/ASKBOT/askbot-devel.git .
virtualenv .
./bin/pip install --upgrade setuptools
./bin/pip install -r askbot_requirements_dev.txt
./bin/python setup.py install develop

Unfortunately the setup doesnt finish due to an error:

Using /var/www/html/askbot-devel/lib/python2.7/site-packages
Finished processing dependencies for askbot==0.7.53
running develop
error: can't create or remove files in install directory

The following error occurred while trying to add or remove files in the
installation directory:

    [Errno 2] No such file or directory: 'build/bdist.linux-x86_64/egg/test-easy-install-36074.write-test'

The installation directory you specified (via --install-dir, --prefix, or
the distutils default setting) was:

    build/bdist.linux-x86_64/egg

This directory does not currently exist.  Please create it and try again, or
choose a different installation directory (using the -d or --install-dir
option).

If I try to add --install-dir or --prefix I recieve the same error. Also if I create the folder manually and run the setup.py again it will just delete it and throw the same error again.

Is there any way to fix this?
