Hey there,

While trying to remap upload URLs since we changed of domain [as mentioned in this thread](https://meta.discourse.org/t/file-urls-broken-after-moving-to-a-different-domain/35502/3), I get the following error:

```bash
/var/www/discourse# script/discourse remap forum.ucoin.io forum.duniter.org

```

I get:

```bash
/usr/local/lib/ruby/site_ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- thor (LoadError)
        from /usr/local/lib/ruby/site_ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:in `require'
        from script/discourse:3:in `<main>'

```

So I cannot perform the remap.

Am I missing something?

Edit: yes I am missing the fact I could run `discourse remap forum.ucoin.io forum.duniter.org` instead.

`gem install thor` solves this.
