You should take a minute to verify that Node.js is installed and working before moving on. To do so, open a command prompt and execute the following command to bring up a Node.js VM:
node
Next, at the Node.js prompt, execute the following to write "Hello World"
to the screen:
>console.log("Hello World");
After you see "Hello World"
written to the console screen, exit the console by pressing Ctrl+C in Windows or Cmd+C on a Mac.
Next, verify that the npm
command is working by executing the following command at the command prompt:
npm version
You should see output similar to the following:
{ http_parser: '1.0',
node: '0.10.21',
v8: '3.14.5.9',
ares: '1.9.0-DEV',
uv: '0.10.18',
zlib: '1.2.3',
modules: '11',
openssl: '1.0.1e',
npm: '1.3.11' }
