How can I update NodeJS and NPM to the next versions?

Question

I just installed Node.js and npm (for additional modules).

How can I update Node.js and the modules which I\'m using to the latest versions

Answer 1

I just installed Node.js on a new Windows 7 machine, with the following results:

> node -v
v0.12.0
> npm -v
2.5.1

I then did the above described procedure:

> npm install -g npm

and it upgraded to v2.7.3. Except than doing npm -v still gave 2.5.1.

I went to the System configuration panel, advanced settings, environment variables. I saw a PATH variable specific to my user account, in addition to the global Path variable.
The former pointed to new npm: C:\Users\PhiLho\AppData\Roaming\npm
The latter includes the path to node: C:\PrgCmdLine\nodejs\ (Nowadays, I avoid to install stuff in Program Files and derivates. Avoiding spaces in paths, and noisy useless protections is saner...)
If I do which npm.cmd (I have Unix utilities installed...), it points to the one in Node.

Anyway, the fix is simple: I just copied the first path (to npm) just before the path to node in the main, global Path variable, and now it picks up the latest version.
;C:\Users\PhiLho\AppData\Roaming\npm;C:\PrgCmdLine\nodejs\

> npm -v
2.7.3

Enjoy. :-)
