# On MacOS X: 
# sudo gem install mysql -- --with-mysql-dir=/usr/local/mysql 
# On Windows: 
# gem install mysql 
# Choose the win32 build. 
# Install MySQL and put its /bin directory on your path.

drop database if exists pomodo_development; 
create database pomodo_development; 
drop database if exists pomodo_test; 
create database pomodo_test; 
drop database if exists pomodo_production; 
create database pomodo_production;

バット私 - 私はまた、次のような問題に直面してのMySQL 5.5

- 私を使用してスクリプトの実行に使用する

mysql -h localhost -u root -p <db\create.sql 
call rake db:migrate RAILS_ENV=pomodo_development --trace` 

誰でも助けることができますか？

Answer 1

RAILS_ENVはdevelopmentである必要があります。まったく指定しないでください（デフォルトはdevelopment）。

環境では、データベースの名前ではありません、それはRailsの環境、一般development、stage、またはproductionの名前です。変数はdatabase.ymlのいずれかの設定と揃う必要があります。
