What's the best way to use multiple version of node AND npm?

[Thomas]

Hi,

After installing a bunch of version of node, npm, modules using different ways, I managed to fuck up my installation… I've deleted of files related to node, npm and node modules to start my installation from scratch.

I'm using Mac OS X Lion and reinstalled the official package coming with npm bundled: http://nodejs.org/dist/v0.6.11/node-v0.6.11.pkg (instead of using homebrew's node version like before).

But I also need node 0.4.x for some project running on Heroku. Unfortunately the npm version bundled with node 0.6.11 doesn't work with node 0.4.x. And it seems that `n` and `nave` can manage node versions but not npm versions. How would you do that?

Thanks

[Dan North]

The nicest way I've found for multiple separate node installs is nodeenv. It works just like Python's virtualenv:

Install a version:
% nodeenv -n 0.6.10 /path/to/node-0.6.10

Use a version:
% source /path/to/node-0.4.6/bin/activate

Now the correct node and npm are in your path. Simples!

To install it just pip install nodeenv (it's a Python script).

Cheers,
Dan

use issacs nave
then install npm

nave is usually compiles node per user, I do a global install of nave,
like this:

https://github.com/isaacs/nave
curl https://raw.github.com/isaacs/nave/master/nave.sh > /usr/local/
bin/nave
chmod +x /usr/local/bin/nave
mkdir /usr/local/lib/nave
nano /usr/local/bin/nave
add after 1st #! line : NAVE_DIR=/usr/local/lib/nave

make sure you have openssl-dev

nave use 0.6.11

install npm:
curl http://npmjs.org/install.sh | sh


now each time you use node 1st type

nave use 0.6.11

node app.js

in a bash init script:

nave use 0.6.11 /dir/app.js

NVM is also an option.

I use nave to manage multiple instances of node, and install everything with npm on 0.6. It never failed me so far but the approach as obvious problems. Most people have a install of npm that works with 0.4 in some folder in their pcs. Then npm link

I prefer https://github.com/mmalecki/give - it leverages `git archive`, and is very fast at switching (after you've installed the given node version).

I'm a big fan of NVM as well [[ https://github.com/creationix/nvm ]].  I've used it on OSX and smartOS (open-solaris-ish) without much trouble.

The travis.ci guys use it as well on their VMs to allow you to test your apps against multiple node versions.

I'll second the vote for n!

Thomas, also see http://devcenter.heroku.com/articles/nodejs-versions

You might not need to switch versions after all

I second nodeenv. It's by far the best thing for system deployments where you may need to run node apps on different node versions simultaneously.
