![]() This can be a problem if you’re trying to upgrade the formula or install it on a different machine. If you try to uninstall a keg-only formula with brew uninstall, Homebrew will only remove the symlinks, not the actual formula files in /usr/local/Cellar. This is so that other formulas can depend on them. Homebrew installs them in /usr/local/Cellar and creates symlinks to their files in /usr/local. Keg-only formulas are formulas that are not available in any other form (e.g.tar.gz or. ![]() However, if you’re trying to uninstall a keg-only formula, these extra files can be a pain to remove manually. There are still files left behind in /usr/local/Cellar/package_name. We’ll put the following in index.If you’ve ever tried to install a package with Homebrew, and then uninstalled it, you may have noticed that the package is not completely removed. Postgres=# grant all privileges on database simple_node_app_db to simple_node_app_user īack to our Node code. Postgres=# create user simple_node_app_user with password 'simple_node_app_pw' Postgres=# create database simple_node_app_db Of course, to communicate with a Postgres database we’ll need one! Here we’ll install Postgres, start it, and then create a new database, user, and grants for this example. We’ll be using the pg, dotenv, and yargs packages. Wrote to /Users/joe/projects/nodejs/simple_node_app/package.json % mkdir ~/projects/nodejs/simple_node_app With NodeJS installed, let’s take it for a spin and write a “simple” application that reads data from a Postgres database.

Nvm via Homebrew is unsupported by them and you should check any Please note that upstream has asked us to make explicit managing Of course you can install nvm using their instructions, or use Homebrew. ![]() Using nvmĪ third method of installing NodeJS is through NVM, the Node Version Manager. NodeJS installed in this manner is not going to support multiple versions and will make your development experience miserable. Npm ERR!

As it turns out that isn’t a Long Term Support (LTS) release. Installing and managing Node versions with Homebrew isn’t too difficult, if you make the decision to only have one version installed at a time. ![]() It’s not uncommon to be developing with multiple NodeJS versions, especially in a professional environment. Now to install a few node packages in the global environment: Installing NodeJS with Homebrew is as simple as running brew install node in your terminal.īoth node (the NodeJS engine) and npm (Node Package Manager) are installed: You can even install it with Homebrew! Homebrew Install ![]() NodeJS can be installed and managing using a number of package managers, just like we saw with Ruby. If you haven’t read Part I, make sure you do and install: In this post let’s look at what needs to be installed on your Mac for developing NodeJS applications. I wrote Part I of this series to provide a foundation upon which to build a collection of minimal guides to developing software on a Mac. ![]()
