heroku db:push - The MySQL server has gone away

I'm trying to push my local development database up to heroku wi开发者_运维问答th heroku db:push but it's not connecting. Anyone know what the problem is?

http://devcenter.heroku.com/articles/taps#import_push_to_heroku

$ heroku db:push --confirm spanish-day-111
Loaded Taps v0.3.23
Auto-detected local database: mysql://root@localhost/blog_development?encoding=utf8
Warning: Data in the app 'spanish-day-111' will be overwritten and will not be recoverable.
Failed to connect to database:
  Sequel::DatabaseConnectionError -> Mysql::ClientError::ServerGoneError: The MySQL server has gone away

Ok finally figured out that I didn't have the mysql gem in my current rvm gemsite.

This fixed the problem for me.

env ARCHFLAGS="-arch x86_64" gem install --no-rdoc --no-ri mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config
