Prerequisites

  1. First, check that you can run node -v and npm -v from a command line. Your 'node' version should be v6 or higher.

  2. If you can't run node -v, you'll need to install it (below).

  3. Once you can run node and npm, make sure you can load packages:

    npm install -g create-react-app

  4. If errors occur, you'll need to configure npm to load packages from an npm "Registry" (below).

1. Installing node

Windows

On Windows, install node from https://nodejs.org/

Mac

On Mac, I use nvm as it doesn't require installing node as root, and we can manage multiple node versions.

  1. Install nvm from https://github.com/creationix/nvm
  2. Run nvm install node

(To list available versions: nvm ls-remote)

Linux

On Linux, install node using your distribution's package manager.

2. Configure npm to use a Registry

If you're not behind a corporate firewall, skip this section.

Does your company have an internal registry (sometimes called a binary repository or Artifactory)? If so, try Option 1 below. Otherwise, use Option 2 below.

Option 1: Use internal Artifactory

Use npm config to set npm to use your company's internal Artifactory. For example:

  • npm config set registry https://artprod.dev.mycompany.com/artifactory/api/npm/npm-repos

    Don't forget to replace "mycompany" with your company's name, or find your company's Artifactory URL from a colleague.

Option 2: Use proxies to access NPMJS registry

If you can't access an Artifactory, try accessing the main npm registry, for example like this:

  • npm config set strict-ssl false

  • npm install -g --registry http://registry.npmjs.org/ --proxy http://proxy.mycompany.com:81/ --https-proxy https://proxy.mycompany.com:81/ --verbose --always-auth=false create-react-app

    Don't forget to replace "mycompany" with your company's name.

This second command will install create-react-app using the settings you provide. (You can also provide the same settings using npm config if you prefer.)
