I have been using this command for quite some time, and until recently it worked very well.
alias pipup='sudo pip install --upgrade $(yolk -U | awk "{print $1} ")'
However, it has recently started failing with the following output any time a package has an available update:
Exception:

Storing debug log for failure in /Users/Bryson/.pip/pip.log
The output of the yolk -U
command executed by this alias in this instance was:
[14:05] Bryson@Zeus ~ :$ yolk -U
pep8 1.5.3 (1.5.4)
setuptools 3.4.1 (3.4.3)
[14:06] Bryson@Zeus ~ :$
When there are no package names/versions returned by yolk
, the command instead outputs the following properly and the alias command does not fail. Instead the following is correctly printed to the terminal:
No newer packages found at The Cheese Shop
You must give at least one requirement to install (see "pip help install")
