Summary
Have the need to downgrade your Node and NPM installations?If so, here's how I downgraded node from v0.10.33 to v0.10.26 and npm from 2.1.9 to 1.3.6.
Run these commands
sudo rm -rf /usr/local/lib/node_modules
echo prefix=~/.node >> ~/.npmrc
brew uninstall node
cd /usr/local
brew versions node|grep 0.10.26 # << this shows the git commit id (bae051d)
git checkout 0901e77 Library/Formula/node.rb
brew unlink node
brew install node
curl -L https://www.npmjs.org/install.sh|pbcopy
# This is when I created the install-npm-1.3.6.sh file
chmod +x install-npm-1.3.6.sh
install-npm-1.3.6.sh
ln -s `which npm` $HOME/.node/bin/npm
Created install-npm-1.3.6.sh File
Replace "latest" text with "1.3.6"
#!/bin/sh
# A word about this shell script:
#
# It must work everywhere, including on systems that lack
# a /bin/bash, map 'sh' to ksh, ksh97, bash, ash, or zsh,
# and potentially have either a posix shell or bourne
# shell living at /bin/sh.
#
# See this helpful document on writing portable shell scripts:
# http://www.gnu.org/s/hello/manual/autoconf/Portable-Shell.html
#
# The only shell it won't ever work on is cmd.exe.
if [ "x$0" = "xsh" ]; then
# run as curl | sh
# on some systems, you can just do cat>npm-install.sh
# which is a bit cuter. But on others, &1 is already closed,
# so catting to another script file won't do anything.

Check Your Downgraded Versions
$ node -v
v0.10.26
\$ npm -v
1.3.6
Notes
To get the correct version of node to checkout you'll need to do something like this:
brew versions node | grep 0.10.26
... and to get brew versions to work you may need to run this:
brew tap homebrew/boneyard
I do not advocate downgrading node and npm.
This was for example purposes.
Reverting Back to Latest Versions
Not sure why any one would want to remove such a useful command, but for the time being you can use the brew versions command to get the git command used to download a specific node version (0.10.33 in our case).
$ brew versions node | grep 0.10.33
Warning: brew-versions is unsupported and will be removed soon.
You should use the homebrew-versions tap instead:
https://github.com/Homebrew/homebrew-versions
0.10.33 git checkout 4b9395f /usr/local/Library/Formula/node.rb
$ brew cleanup
$ brew cleanup --cache
$ cd /usr/local/Library/
$ git checkout 4b9395f /usr/local/Library/Formula/node.rb
$ brew install node
Notes
No other combination of brew commands would upgrade node from 0.10.26 to 0.10.33.So, none of these had any other effect, other than keeping node at version 0.10.26:
$ brew uninstall node
$ brew upgrade
$ brew cleanup
$ brew cleanup --cache
$ brew upgrade node
Verify Versions
Verify that both node and npm are back to the latest versions:
~ $ node -v
v0.10.33
~ $ npm -v
2.1.9
