EACCES is an error of not having access on doing an operation.

Taken the line: npm ERR! Error: EACCES, mkdir '/usr/local/lib/node_modules/bower' we can see that npm was unable to create a directory in the given location.

The reason is very likely that you are not running the command as super user. In fact, the error log is even suggesting that:

npm ERR! Please try running this command again as root/Administrator.

To run as administrator, you have to prefix those commands with sudo. That is:

sudo npm install -g bower. You will be required to type in a password for security reasons.
