通常的数据库连接的问题，检查下database.yml文件。

你看看这个有问题么？谢谢


# MySQL (default setup). Versions 4.1 and 5.0 are recommended.
#
# Install the MySQL driver:
# gem install mysql
# On MacOS X:
# gem install mysql -- --include=/usr/local/lib
# On Windows:
# gem install mysql
#   Choose the win32 build.
#   Install MySQL and put its /bin directory on your path.
#
# And be sure to use new-style password hashing:
# http://dev.mysql.com/doc/refman/5.0/en/old-client.html
development:
 adapter: mysql
 database: depot_development
 username: root
 password:
 host: localhost

# Warning: The database defined as 'test' will be erased and
# re-generated from your development database when you run 'rake'.
# Do not set this db to the same as development or production.
test:
 adapter: mysql
 database: depot_test
 username:root
 password:
host: localhost

production:
 adapter: mysql
 database: depot_production
 username: root
 password:
 host: localhost

密码有空格，删掉空格

K:\>cd Work

K:\Work>cd depot

K:\Work\depot>ruby script/generate scaffold Product Admin
这次是这个错误勒！是不是没有这个数据库的意思啊？但是我建了的勒

和Bless4me一样的错。

不一样吧

是不是与中文路径有关系啊？
看不出这个错误

不会吧！还认中文路径问题啊？老火勒！

发现勒！并不是中文问题！database.yml需要这样写，例如
development:
 adapter:*mysql
 database:*depot_development
 username:*root
 password:*你的密码
 host:*localhost

test:
 adapter:*mysql
 database:*depot_test
 username:*root
 password:*你的密码
 host:*localhost

production:
 adapter:*mysql
 database:*depot_production
 username:*root
 password:*你的密码
 host:*localhost

注意：每个子节点下面必须要有一个空格，就是上面的*代表空格
希望大家都能够学得更好！
