I have been trying to install Derby, and npm keeps insisting it cannot find a suitable version of express. Here’s the command I am using: npm install -g derby. Below is the output. I am running Ubuntu 11.10, node v0.7.6 and npm v1.1.17. Am I doing something wrong? How can I fix this?

    Derby requires express v2.x, and express v2.x requires node v0.4.1 => 0.7.0-pre. That means that npm won’t be able to find a valid version of express for you, since your node version, v0.7.6, isn’t supported.

    Your best bet would be to downgrade Node. You can also manually install express, and hope that it’s actually compatible, but that’s probably a bad idea.
