installing github master produces errors

[propertunist]

following the advice in the issue regarding the toString errors.. i chose to install the github master version of critical using:

sudo npm install http://github.com/addyosmani/critical/tarball/master

towards the end of the terminal output, i saw more errors:

i looked into the debug log that is mentioned and did not see any info in there that was helpful to me in diagnosing the cause fo the errors.

i updated the package.json to address this issue.
Can you please try again?

[bezoerb]

you should not use sudo npm install to install local packages.

ok, i did originally not use sudo; however, i got permission errors and more errors that way.
i just ran the process again without sudo and all looks good this time, thanks.
from what i can see, the critical process did not produce any output against my test file, so there is still some issue of some form to resolve, though the download and install from github looks ok. thanks
