在mac上装rails时遇到Unable to resolve dependencies错误

[blankyao]

想学习下rails的,结果装都没装上,具体的报错信息如下所示,即使手动安装这些依赖的包也装不上,好像是循环依赖了
哪位同学遇到过同样的问题?或者介绍一下其他方法来安装rails

ERROR: While executing gem ... (Gem::DependencyError)
Unable to resolve dependencies: rails requires activesupport (= 3.0.9), actionpack (= 3.0.9), activerecord (= 3.0.9), activeresource (= 3.0.9), actionmailer (= 3.0.9), railties (= 3.0.9), bundler (~> 1.0)

@roamlog 在gem install rails这步卡住了,依赖问题搞不定

[daqing]

把你的ruby版本, gem版本都报一下吧。

[daqing]

还有，试试这个命令:

$ gem install rails --debug -V

然后把输出贴到某个地方，或者email我。

[Los]

gem update --system
先升级gem自身，保证gem版本是最新的

最前面加 sudo了吗

@Los 已经试过了,升级到最新版本了

[blankyao]

@Wowbeing 加不加都试过了,都不行

[daqing]

你用的是rvm ree，要不要先试试1.8.7?

$ rvm install 1.8.7
$ rvm use 1.8.7 --default

然后在*新的shell*中安装rails:

$ gem install rails -V

[real_newbie]

试试1.9.2看看. 是不是装REE的时候用了sudo啊? 用了rvm, 就不要sudo了.

[blankyao]

@daqing 还是不行,我继续折腾折腾

[Los]

@blankyao 直接安装3.1版本看看: gem install rails --pre
