爲什麼Rake因「壞文件描述符」而中止？

Question

我在使用rake db:create創建數據庫時遇到問題。

我遵循「Fat Free CRM Guides: Installation on Microsoft Windows」指南在Windows上安裝Fat Free CRM。

我在32位Windows 7上。Rake是0.8.7。 RubyGems是2.0.3，Ruby是1.9.3。我正在使用MySQL2 v0.2.6。

我得到的錯誤是：

C:\RailsInstaller\fat_free_crm>rake db:create RAILS_ENV=production --trace 
** Invoke db:create (first_time) 
** Invoke db:load_config (first_time) 
** Execute db:load_config 
** Invoke rails_env (first_time) 
** Execute rails_env 
** Execute db:create 
rake aborted!

C:\RailsInstaller\fat_free_crm>[/code] 

我改變的libmysql.dll爲WIN7 - 32位

database.yml中的配置是：

development: 
adapter: mysql2 
encoding: utf8 
database: fat_free_crm_development 
pool: 5 
username: root 
password: ale 
#socket: /var/run/mysqld/mysqld.sock 
host: localhost 
#host: 127.0.0.1 
port: 3306 

test: 
#<<: *development 
database: fat_free_crm_test 

production: 
#<<: *development 
adapter: mysql2 
encoding: utf8 
#database: crm_production 
database: fat_free_crm_production 
pool: 5 
username: root 
password: ale 
#socket: /tmp/mysql.sock 
#host: 127.0.0.1 
host: localhost 
port: 3306 

staging: 
#<<: *development 
database: fat_free_crm_staging 

沒有人有任何的想法？

在第9,25,29,43行刪除了&development和<<*development。我認爲你的database.yml文件中有語法錯誤。
