Use io.js and Node.js with Homebrew at OS X
Install io.js and Node.js with homebrew is super easy:
brew install iojs node
But you make notice this message for io.js formula:
This formula is keg-only.
iojs conflicts with node (which is currently more established)
Because of io.js uses
node for its binary’s name, so Homebrew won’t link io.js’s binary to
/usr/local/bin, unless force to link with command
brew link iojs --force. That means you can’t use io.js directly (e.g.
node app.js). You have to use absolute path (e.g.
/usr/local/Cellar/iojs/1.0.4/bin/node app.js), or use nvm:
nvm use 0.11 node -v # v0.11.15 nvm use iojs node -v # v1.0.4
Although it can work, but you have to change asolute path after io.js updated, or
nvm may be unavailable in some situations (e.g. needs
source $NVM_PATH/nvm.sh). It’s inconvenience. So I created a shell script to help things easier:
#!/usr/bin/env sh if [ -d "$(brew --prefix)/Cellar" ]; then node=`find /usr/local/Cellar -name node | grep iojs/.*/bin/node` if [ ! -z "$node" ]; then $node $@ else echo "io.js not installed" fi else echo "Homebrew folder not found" fi
This script searches io.js’s binary in Homebrew’s
Cellar folder, and run it with passed arguments. You can consider it is an alias of
/usr/local/Cellar/iojs/1.0.4/bin/node, except it will maintain version for you.
All you need to do is put this script into your
$PATH and make it executable. If you don’t know how to, here is a guide:
cd $HOME touch .bash_profile # or .bashsrc, .zshrc, depends on your environment echo 'export PATH="$HOME/.scripts:$PATH"' >> .bash_profile mkdir .script && cd $_ touch iojs && chmod +x iojs open -a "EDITOR" iojs
EDITOR to your favorite editor, then copy and paste the shell script into the file, and save.
That’s all. You can now run io.js and Node.js like this:
node -v # v0.11.15 iojs -v # v1.0.4 node app_for_node.js iojs app_for_iojs.js
Note that this script can’t handle multiple versions for now, so after io.js updated, remember to run
The shell script is published on Gist.
