Heroku db:Push - Sequel Adapter NOt Found

Question

I know there a number of posts similar to this one and yet I still seem to be unable to solve my problem. So if I have missed something, feel free to explain it like you would to a child. :)

I am trying to push data from my local machine which uses Mysql to Heroku which uses Postgres.

The command heroku db:push sometable -t generates the error message below:

Failed to connect to database Sequel::AdapterNotFound -> LoadError cannot load such file

I have also tried:

heroku db:push -t sometable mysql://user:password@localhost/db_name

Added info:

1. Using Windows 7
2. Using Rails 3.2.8
3. Using Ruby 1.9.3
4. Mysql gem is installed and works with Rails
5. Heroku client is up to date
6. Database is running
7. Heroku db schema is running.
8. Rails was installed with RailsInstaller 1.92

Any suggestions would be greatly appeciated. Thanks in advance.

Answer 1

I had a similar issue and was able to get it working using standard heroku gem.

I installed Heroku through their site downloader - 'Heroku Toolbelt' package for windows. That didn't work so in addition I also installed

Heroku gem and all dependencies. (ignore deprecation warning)

sqlite3 gem for taps (i don't use sqlite, but heroku needs it)

then it worked!

Heroku uses PostgreSQL as database. You should not get this error if you install pg.

Try to run: gem install pg
