As for the first error, this is the error we were expecting (see 2:09 in the video). It's because we hadn't initialized an npm project but it should have still installed the node_modules. Did you make a directory called selenium_basics or something to work on the project in? Are you running ls in the same directory?

As for the last error, try using sudo:

sudo npm install chromedriver -g

This is what he does at 2:53 in the video.
