What is the suggested way to install brew, node.js

Question

I am trying to use homebrew as much as possible. What's the suggested way to install the following on OS X?

• node.js
• io.js
• nvm
• npm

and hopefully supports development for:

• ionic
• ngCordova

Answer 1

If you have previously installed node using brew, then you will have a bunch of extra files that you should clean up before installing node "the right way". Plus, I had to add a few settings to my startup script to make things work smoothly.

I wrote a script to make this easy.

# filename:  install-nvm-npm-node
# author:    Lex Sheehan
# purpose:   To cleanly install NVM, NODE and NPM
# dependencies:  brew

NOW=$(date +%x\ %H:%M:%S)
CR=$'\n'
REV=$(tput rev)
OFF=$(tput sgr0)
BACKUP_DIR=$HOME/backups/nvm-npm-bower-caches/$NOW
MY_NAME=$(basename $0)
NODE_VER_TO_INSTALL=$1
if [ "$NODE_VER_TO_INSTALL" == "" ]; then
    NODE_VER_TO_INSTALL=v0.12.2
fi
if [ "`echo "$NODE_VER_TO_INSTALL" | cut -c1-1`" != "v" ]; then
    echo """$CR""Usage:   $ $MY_NAME <NODE_VERSION_TO_INSALL>"
    echo "Example: $ $MY_NAME v0.12.1"
    echo "Example: $ $MY_NAME $CR"
    exit 1
fi
echo """$CR""First, run:  $ brew update"
echo "Likely, you'll need to do what it suggests."
echo "Likely, you'll need to run: $ brew update$CR"
echo "To install latest node version, run the following command to get the latest version:  $ nvm ls-remote"
echo "... and pass the version number you want as the only param to $MY_NAME. $CR"
echo "Are you ready to install the latest version of nvm and npm and node version $NODE_VER_TO_INSTALL ?$CR"
echo "Press CTL+C to exit --or-- Enter to continue..."
read x

echo """$REV""Uninstalling nvm...$CR$OFF"
# Making backups, but in all likelyhood you'll just reinstall them (and won't need these backups)
if [ ! -d "$BACKUP_DIR" ]; then 
    echo "Creating directory to store $HOME/.nvm .npm and .bower cache backups: $BACKUP_DIR"
    mkdir -p $BACKUP_DIR

echo "Now, all is likley well if you can run the following without errors:  npm install -g grunt-cli$CR"
echo "Other recommended global installs: bower, gulp, yo, node-inspector$CR"

I wrote a short article here that details why this is "the right way".

If you need to install iojs, do so using nvm like this:

nvm install iojs-v1.7.1

To install brew, just see its home page.

See alexpods answer for the rest.

Answer 2

2018 Version

In most of the answers , recommended way to install nvm is to use Homebrew

Do not do that

At Github Page for nvm it is clearly called out:

Homebrew installation is not supported. If you have issues with homebrew-installed nvm, please brew uninstall it, and install it using the instructions below, before filing an issue.

Use the following method instead

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | bash

The script clones the nvm repository to ~/.nvm and adds the source line to your profile (~/.bash_profile, ~/.zshrc, ~/.profile, or ~/.bashrc).

And then use nvm to install node. For example to install latest LTS version do:

nvm install v8.11.1

Clean and hassle free. It would mark this as your default node version as well so you should be all set

Answer 3

I agree with noa -- if you need to have multiple versions of node, io.js then brew is not the appropriate solution.

You can help beta-test io.js support in nvm: https://github.com/creationix/nvm/pull/616

If you just want io.js and are not switching versions, then you can install the binary distribution of io.js from https://iojs.org/dist/v1.0.2/iojs-v1.0.2-darwin-x64.tar.gz ; that includes npm and you will not need nvm if you are not switching versions.

Remember to update npm after installing: sudo npm install -g npm@latest

Answer 4

Here's what I do:

curl https://raw.githubusercontent.com/creationix/nvm/v0.20.0/install.sh | bash
cd / && . ~/.nvm/nvm.sh && nvm install 0.10.35
. ~/.nvm/nvm.sh && nvm alias default 0.10.35

No Homebrew for this one.

nvm soon will support io.js, but not at time of posting: https://github.com/creationix/nvm/issues/590

Then install everything else, per-project, with a package.json and npm install.

Answer 5

I'm using n (Node version management)

You can install it in two ways

brew install n

or

npm install -g n

You can switch between different version of node and io. Here's an example from my current env when I call n without params:

$ n

  io/3.3.1
  node/0.12.7
  node/4.0.0
  node/5.0.0
ο node/5.10.1 

Answer 6

For install with zsh and Homebrew:

brew install nvm

Then Add the following to ~/.zshrc or your desired shell configuration file:

export NVM_DIR="$HOME/.nvm"
. "/usr/local/opt/nvm/nvm.sh"

Then install a node version and use it.

nvm install 7.10.1
nvm use 7.10.1
