make的时候需要调用ruby很多编译前的参数.一些信息make不知道的话会不知道如何建库.我个人的建议是根据你安装的ruby路径和版本信息把配置选项补充全.下面是我电脑上面的配置,你可以借鉴一下.据我分析应该能解决你的问题.
Provided configuration options:
--with-opt-dir
--with-opt-include
--without-opt-include=${opt-dir}/include
--with-opt-lib
--without-opt-lib=${opt-dir}/usr/lib
--with-make-prog
--without-make-prog
--srcdir=.
--curdir
--ruby=/usr/local/ruby-2.1.2/rubies/ruby-2.1.2/bin/ruby
首先用一个在Rails开发中一定会遇到的YAML文件——database.yml——作为示例。在你创建一个Rails工程后,Rails会自动给你创建一个这样的文件,它的路径是config/database.yml:# MySQL (default setup). Versions 4.1 and 5.0 are recommended.
# 此处省略一些注释。
development:
adapter: mysql
database: demo_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: demo_test
username: root
password:
host: localhost
production:
adapter: mysql
database: demo_production
username: root
password:
host: localhost
