Pelican 3.3 pelican-quickstart error "ValueError: unknown locale: UTF-8"

When I was trying to use pelican3.3, I typed the commend "pelican-quickstart", some errors showed up.

These are the errors:

My OS is OS X Mavericks.

You could try a solution posted here or here. Basically, add some lines to your ~/.bash_profile:

    export LC_ALL=en_US.UTF-8
    export LANG=en_US.UTF-8

There is an outstanding bug report related to this issue. It appears that Python makes some assumptions about the format of locale names that aren't universally valid. Explicitly setting these environment vars is basically just a workaround for that bug.

[Edit:] As @asmeurer correctly points out, the above fix assumes English and the U.S. You should really pick your preferred locale from the list given by locale -a (generally one that ends in UTF-8).
