The MetaEd IDE installation steps are fairly straightforward. It's worth noting that the MetaEd IDE is a plug-in to the free, open source Atom text editor. The installation steps below walk you through a complete install assuming you haven't yet installed Atom.
The installation steps can be summarized as:
Detail on each step follows.
Step 1. Create a Project Folder
Create a project folder containing a folder called "MetaEd-IDE". The path to this folder should be short (e.g. "C:\Project\MetaEd-IDE") and should not contain spaces.
Step 2. Download and Unzip the MetaEd IDE Installation Files
An Ed-Fi community login is required to access MetaEd IDE downloads. If you don't have a login, you can sign up here.
Download the MetaEd IDE Installation ZIP file from the Downloads section of this documentation. This will require agreeing to an end-user license for the software.
Save the files to the new MetaEd-IDE folder. These are configuration files that enable the installation and updating of the MetaEd IDE via the Yarn Package Manager. You'll install Yarn in a later step.
Step 3. Download and Install the Atom Text Editor
Download and install the latest version of the Atom text editor from the website https://atom.io.
Download and install the latest version of the Yarn package manager from the website https://yarnpkg.com/en/. Version 1.16 or greater is required.
Note the recommendation to use Yarn 1.16 or greater. Some users have reported issues using earlier versions.
Step 6. Install the MetaEd IDE
Open a command prompt, and from your MetaEd-IDE directory type the command yarn install and press Enter.
While the command is running, you may notice some warnings displayed in the command prompt, as shown in the example below. These do not indicate problems and may be safely ignored. A final message showing "success" in green indicates a successful installation.
