How to install Gatsby@2(beta)

Question

How to install Gatsby@v2? I followed documentation at https://next.gatsbyjs.org/docs/ which is supposed to be docs for the new version. It says to run npm install --global gatsby-cli. But this command installs version 1. How do I install 2nd version?

Answer 1

If you want to start a new project from scratch, you can do

$ mkdir my-new-app
$ cd my-new-app/

Then install the Gatsby and React libraries with Yarn:

$ yarn init -y
$ yarn add gatsby@next react react-dom

To check if you're using the version 2 of Gatsby, open the package.json file in your project folder, you should see something like:

"dependencies": {
  "gatsby": "^2.0.0-beta.16",
  "react": "^16.4.1",
  "react-dom": "^16.4.1"
}

To update the Gatsby CLI to version 2, in the terminal do:

$ npm install --global [email protected]

Then check the CLI version by

$ gatsby -v

The Gatsby CLI version is not the Gatsby library version, and gatsby new may or may not give you the latest version you want, so it is always best to check package.json to verify the Gatsby version

Answer 2

Gatsby 2.0 is currently tagged as next so you need to run npm install --global gatsby-cli@next.

Also, you can check which bin file is used if you run gatsby -v by running which gatsby or also for all your found bins in the $PATH by running where gatsby. Whichever paths these commands return, remove the bin files (e.g. rm /usr/local/bin/gatsby or something like that) and then run npm install --global gatsby-cli@next again.
