Update the Ghost CLI

Some operations such as upgrading Ghost require updating the Ghost CLI. Follow these steps:

    $ cd /opt/bitnami/ghost/current
    $ sudo npm install ghost-cli

You may see warnings related to package.json during the update process. These warnings can safely be ignored.

TIP: If the npm install command fails, run the following:

$ sudo mv package.json package.json.back
$ sudo npm install ghost-cli
$ sudo mv package.json.back package.json
