install issue - sudo needed?

[mgrider]

Installing on a mac, I got the following errors:

okay... guess I need sudo? (Even though that isn't mentioned on http://docs.spark.io/cli/

[Dec 26 10:23:07] $ sudo npm install -g spark-cli

> serialport@1.4.5 install /usr/local/lib/node_modules/spark-cli/node_modules/serialport

Do I need to do anything here? Move the tmp dir? How could root not have privileges for my home dir?

I guess sudo should work since its a global installation

I've always had to use sudo to get it installed. The repo mentions this:
https://github.com/spark/spark-cli

Need to update docs, thanks!

Dropping this link here for future reference: fixing npm permissions

Pick one of the two steps described in the link above, and you should no longer have permissions errors when installing global npm modules! 😸
