forgot to install express

page 201

Gregory Hill was kind enough to write me and point out that on page 201 in Chapter 6, we copy the Tweet Counter’s server.js file into a new location, but we never install express in that directory. If you try to run the program as-is, you’ll get an error. So make sure you run the following command before running the server.

$ npm install express@3

I’ve also included instructions on how to use Express 4 in your app if you’re interested.
