Installation
In this guide we’ll cover all the different ways of installing Embark on your local machine, starting with prerequisites.
Prerequisites
In order to make Embark work on our computer, we need to have some tools installed first. Make sure you have the following ready and in the correct version:
Once done, go ahead and install Embark.
Node
Please install Node.js in version 8.11.3 LTS or higher.
Quick Tip
We recommend installing Node using the Node Version Manager. This is because it makes it very easy to install different versions of Node in isolated environments that don’t require users to change their permissions when installing packages. Find instructions on how to install NVM here.
Once that is done, we can install and select a specific Node version or use the --lts option to get the latest version with long term support like this:
$ nvm install --lts
$ nvm use --lts
IPFS (Optional)
IPFS can be used to distribute our application’s content on the decentralized IPFS nodes. This can be skipped in case this isn’t planned, however we do recommend it. Checkout IPFS’ installation guide to learn how to install IPFS on our local machine.
To verify that the installation was successful, simply run the following command:
$ ipfs --version |
This outputs something like
$ ipfs version 0.4.17 |
Ethereum Client (Optional)
Embark can spin up an Ethereum node for us. To make this happen, an Ethereum client has to be installed on our machine as well. Embark already comes with Ganache CLI, a blockchain node emulator, which is accessible via Embark’s simulator command.
In case we want to run a real node, geth is a pretty good one. Check out the installation guide for our platform and verify our installation with:
$ geth version |
Which should result in an output that looks like this (note that the exact version numbers may be different):
Geth |
Installing Embark
Alright, let’s install Embark so we can build our first application. As mentioned earlier, if anything is unclear or you run into problems, make sure to reach out to us on our dedicated channels, submit an issue on GitHub, or take a look at our troubleshooting guide.
We can install Embark using the Node Package Manager (no worries, that one comes with Node), like this:
$ npm -g install embark |
After that, embark should be available as a global command in our terminal of choice. Let’s verify this by running the following command:
$ embark --version |
At the time of writing this guide, the output looked like this:
4.0.0 |
Awesome! We’re all set up. If you’re brand new to Embark, now would be a good time to take our Quickstart in which you’ll build your first application!
