#2 楼 @badboy 如果真正的做到了，具有行业竞争力的薪酬福利。 找人很容易的

在酒店上班、办公？

要是 rails 有自带的方法就好了。

#1 楼 @special 好的，谢谢

#7 楼 @flowerwrong ruby 也是各种 gem，代码方便快捷，开发速度快

#3 楼 @flowerwrong 如果是新项目，互联网的项目 你怎么定 什么情况用java，什么情况用ruby？

假如说，一个大的项目（互联网项目）按模块划分，请问，哪些模块适合java做，哪些适合ruby做？

好贴，撸主辛苦了

好贴，楼主继续完善

感谢楼主，从填坑开始

rubymine 里面也是无法调试：

#9 楼 @colorfulberry 不行，还是报错

可以安装 1.9.x 的 ruby，不能安装 2.x 的 ruby

系统环境为:Ubuntu 14.04.1 LTS 开发工具已经安装了

#1 楼 @xwf286 假如说是把 A 主机发布到 B 主机上去 请问，是 A 上面的版本太高，还是 B 上面的版本太高

谢谢大家，这个问题已经解决。 安装 rvm 后，默认是添加到 .bash_profile 里面的 改成添加到 .bashrc 就没问题了

#2 楼 @tzwm

按 tab，没有反映，也没有提示

#3 楼 @wppurking

ENV.each do |k,v|
puts k.to_s + ' = ' + v.to_s
end

谢谢

#1 楼 @huacnlee 不是 zlib 的原因，是 zlib-devel 的原因 但是，我在安装 openssl 的时候，又报错了： $cd ext/openssl $ruby ./extconf.rb $make

compiling ossl_pkey_ec.c compiling ossl_bn.c compiling ossl_config.c make: *** No rule to make target /thread_native.h', needed byossl.o'. Stop.

这是什么错

没用过 rvm，我一般是用源码编译安装 ruby，然后 gem install rails 安装 rails

#7 楼 @themorecolor 你是说，在启动 rubymine 的时候，先运行 ulimit -c unlimited 命令？

英文不好 都有些什么东西？

#4 楼 @Martin91 大部分是满足了，够用了。 但是，总有很复杂的，只能用 SQL

#1 楼 @hz_qiuyuanxin 文档里面是写死的参数，我想动态传入参数
