(major edits below–second attempt)
Working on the message import process, using the instructions at [Migrate from another forum to Discourse](https://meta.discourse.org/t/migrating-to-discourse-from-another-forum-software/16616). As I understand them, the process should look like:
- Set up development environment using [Install Discourse on Ubuntu or Debian for Development](https://meta.discourse.org/t/beginners-guide-to-install-discourse-on-ubuntu-for-development/14727)
- Install MongoDB on that system
- On that system, as the same non-privileged user that’s running Discourse, `git clone` the yahoo-group-export script
- As the same user, `gem install mechanize`; `gem install mongo`. Then edit .config.yaml to give the Yahoo credentials and group name, and run `ruby bin/yg-export.rb`.
- Have a cup (or two) of your beverage of choice.
- Once yg-export finishes, in the Discourse directory, take a look at `script/import_scripts/yahoogroup.rb`. Edit it to point to the correct MONGODB\_HOST (localhost).
- In the discourse directory, run `bundle exec ruby script/import_scripts/yahoogroup.rb`
- Verify it’s imported correctly
- Backup and restore to a live server
Steps 2-4 are inferred. But does this look like the right steps to follow? Believing they were, I proceeded. It ran fine through step 4–`yg-export.rb` ran for about an how, reporting SUCCESS for everything, and saving ~38k messages. The database `syncro` is present with ~85MB of data in it. At that point, I took a snapshot of the VM.
I’m having trouble with the import script, though. When I run `bundle exec ruby script/import_scripts/yahoogroup.rb`, I get this:
```plaintext
dan@ubuntu:~/discourse$ bundle exec ruby script/import_scripts/yahoogroup.rb
Traceback (most recent call last):

```
Strange, I thought I’d already installed the `mongo` gem. Well, I’ll do it again:
```plaintext
dan@ubuntu:~/discourse$ gem install mongo
Successfully installed mongo-2.10.2
Parsing documentation for mongo-2.10.2
Done installing documentation for mongo after 4 seconds
1 gem installed
```
Run the import script again, same result. Does it matter if I install it at the system level?
```plaintext
dan@ubuntu:~/discourse$ sudo apt install ruby-mongo
[sudo] password for dan:

ruby-mongo is already the newest version (2.5.1-1).

Curiouser and curiouser…
