Appendix A instructions fail

Hi, I was following along the express-spdy install but it fails on section A.5 when I try to install express:

$ npm install -g express
npm ERR! Unsupported

I am using node 0.5.3 (the latest as you note on your blog that 0.5.4 doesn’t work) on 64-Bit Ubuntu Natty. The express git repo says version 3.x is compatible with 0.5.x of node so I tried:

$ npm install -g express@">=3.0"

I also tried installing directly from a clone of the express repo:

I’d like to give it a try, can you suggest how to install express?

Thanks,

Ah, sorry about that.

Use:

npm install -g express-unstable

The latest instructions are always here: https://github.com/eee-c/express-spdy/blob/mast…

I just noticed that, even there, I was saying to npm install -g express, but I have fixed them to use express-unstable.

Cool it works! Thanks!
