Hi. I’m having the same trouble here when running this script but those commands are not helping… This is the output I get when trying to run the `su discourse -c 'export IMPORT=1; bundle exec ruby script/import_scripts/vanilla_mysql.rb'`:

```plaintext
root@ip-xxx-xx-xx-xx-app:/var/www/discourse# su discourse -c 'export IMPORT=1; bundle exec ruby script/import_scripts/snuffhouse.rb'
You are trying to install in deployment mode after changing
your Gemfile. Run `bundle install` elsewhere and add the
updated Gemfile.lock to version control.

If this is a development machine, remove the /var/www/discourse/Gemfile freeze
by running `bundle config unset deployment`.

The list of sources changed
The dependencies in your gemfile changed

You have added to the Gemfile:
* mysql2
* redcarpet
* sqlite3 (~> 1.3, >= 1.3.13)
* ruby-bbcode-to-md
* reverse_markdown
* tiny_tds
* csv

```
