Problem for merge two forum

Hello to all,

I have made good progress on my problem.

Now I’m stuck just before the import script is executed.

I run bundle install and then IMPORT=1 bundle install and at this point I get this error

An error occurred while installing tiny_tds(2.1.5, and Bundler cannot continue

I still run the full command IMPORT=1 DB_NAME=copyme DB_PASS=password SOURCE_BASE_URL= UPLOADS_PATH=/var/www/discourse/public/uploads/default bundle exec ruby script/bulk_import/discourse_merger.rb

This time, it’s this error

The git source https://github.com/nlalonde/ruby-bbcode-to-md is not yet checked out. 
Please run `bundle install` before trying to start your application

Do you have an idea?
Thanks
