This is Bevry's supported guide for installing Node.js on your computer as well as any other required dependencies for your particular system. This guide is Bevry's supported guide, as we've found other guides will leave you with an incorrectly configured environment causing permission errors and missing executables that are hard to track down.
Install Command Line Tools:
Xcode may or may not be necessary for the above command, if it fails, Download & Install Xcode, and try again.
Ensure correct permissions are set for
sudo chown -R $USER /usr/local
sudo apt-get updatesudo apt-get install curl build-essential openssl libssl-dev git python
sudo yum -y install tcsh scons gcc-c++ glibc-devel openssl-devel git python
Node Version Manager aka NVM lets you install multiple versions of Node.js to your local user directory, enabling easy upgrades and version switching, without the permission troubles that are common with non-NVM setups.
Uninstall any previous Node.js versions you may already have
Install NVM by running the following in Terminal:
git clone git://github.com/creationix/nvm.git ~/.nvmprintf "\n\n# NVM\nif [ -s ~/.nvm/nvm.sh ]; then\n\tNVM_DIR=~/.nvm\n\tsource ~/.nvm/nvm.sh\nfi" >> ~/.bashrcNVM_DIR=~/.nvmsource ~/.nvm/nvm.sh
Install Node.js by running the following in Terminal:
nvm install nodenvm alias default nodenvm use node
IMPORTANT. When installing, make sure you install with the option of making git available to the windows command line.
