pip does not work

[sabernar]

pip install fails:

/usr/local/var/www/myApp $ pip install Flask-Dashed
Downloading/unpacking Flask-Dashed
 Could not find a version that satisfies the requirement Flask-Dashed (from versions:  0.1b, 0.1b2, 0.1a)
Cleaning up...
No distributions matching the version for Flask-Dashed

This is due to a change in how pip 1.4 handles "pre-release" versions and Flask-Dashed having a beta 2 flag (0.1b2).

Use the --pre flag: pip install Flask-Dashed --pre
