I was upgrading my blog(ghost) from `v2.x` to `v3.x` and encountered a strange error with the ghost-cli command.

TL;DR Check compatibility of ghost-cli with nodejs version

As usual, I fired up the terminal and ran the command:

```
ghost update

```

and got the strange error.

```
ghost update

/usr/lib/node_modules/ghost-cli/lib/command.js:108
    static async _run(commandName, argv = {}, extensions) {
                 ^^^^

SyntaxError: Unexpected identifier

    at require (internal/module.js:20:19)
    at Object.<anonymous> (/usr/lib/node_modules/ghost-cli/lib/bootstrap.js:6:17)

```

That seemed an odd error and was giving nothing for me to debug. I checked the Ghost Github issue tracker for any clues, but to my dismay it did not give me any clues either.

But after looking through the documentation, I noticed the the supported nodejs versions document [here](https://ghost.org/faq/node-versions/?ref=til.codes)

And to my surprise, I was running nodejs v6, which is not supported by ghost anymore.

So that was the clue that I needed, and I went ahead with upgrading my nodejs version to `10.x` and 🎉 it fixed the issue with the ghost-cli.

###### Commands to upgrade nodejs version(taken from the faq page above)

To upgrade the steps are:

```
# update your source list with the version of Node.js you want to upgrade to.
curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash

# upgrade Node/ks
sudo apt-get install -y nodejs

# force Ghost to update even if there are no new versions of Ghost,
# to trigger a re-install of dependencies.
ghost update --force

```

That was smooth.

Enjoy.!
