Not compatible with your version of node/npm: ghost-cli

This seems to be because you’ve just symlinked the /usr/bin/ghost binary to /usr/local/bin/ghost, but during the installation it is trying to symlink from ../lib/node_modules/ghost-cli/bin/ghost to /usr/local/bin/ghost and detects the issue.

I would try:

  1. rm /usr/bin/ghost
  2. sudo npm install -g ghost-cli@latest

Alternatively you can:

  1. rm /usr/bin/ghost
  2. mv /usr/local/bin/ghost2 /usr/local/bin/ghost
