TRAC installation fails with UnknownLocaleError

[anonymous]

I' trying to install latest TRAC dev with easy_install on Ubuntu 12.04 LTS Server. Installing Babel and Genshi works fine, but trying to install TARC itself fails with an UnknownLocaleError:

sudo easy_install -z -U Trac==dev

babel.core.UnknownLocaleError: unknown locale 'fa'

tryed with Babel 0.9.5 and 0.9.6 Installation without Babel works fine.

[Jun Omae]

This is an InstallationIssue, please use the MailingList and IrcChannel.

And, it seems that Babel on your environment has an installation issue. Babel supports fa locale. Try the following command:

$ python -c 'from babel import Locale; Locale("fa")'

If the command fails with the same UnknownLocaleError exception, re-install Babel using apt-get install python-babel.

This seems to be an issue related to Python-Babel in general. The only solution for me was removing python-babel entirely.

Replying to Sean:

What mechanism did you use to install Babel? I believe that I've encountered this issue when installing from source and not following all of the steps: babel:SubversionCheckout.
