Installing Node

You can use nvm to install and manage Node on your machine. Copy the install script and run it:

1 curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.30.1/install.sh | b\
2 ash

After that, make a new terminal window and make sure that it is installed, by running:

1 nvm --help

Now you can use nvm to install Node 0.12.9 by running:

1 nvm install 0.12.9

After that, nvm is going to load version 0.12.9 automatically. If it doesn’t, you can load it in the current shell, with:

1 nvm use 0.12.9

Note that you can load any node version in the current shell with nvm use 0.x.y after installing that version.

Also note that if you want to make 0.12.9 the default Node version on your machine, you can do so by running the following:

1 nvm alias default 0.12.9

Then you can verify that it is the default version by making a new terminal window and typing node -v.

Permissions

Never use sudo to install packages, never do sudo npm install <package>. If you get permission errors while installing without sudo, you can own the folders instead. So for example, if you get an error like:

1 Error: EACCES, mkdir '/usr/local'

you can own the folder with:

1 sudo chown -R `whoami` /usr/local

You can own folders until Node doesn’t complain.

Installing live-server

Install a package to verify that node is installed and everything is wired up correctly. We are going to use live-server through the book. So let’s install that with:

1 npm i -g live-server

Then, you should be able to run live-server in any folder to serve the content of that folder:

1 mdkir ~/Desktop/sample && cd $_
2 live-server .
