Shy*_*ani 6 ruby ruby-on-rails railstutorial.org
你好,我是铁路新手.我正在关注Michael Hartl的railstutorial.org.我陷入了清单4.5的第4章:当我点击$ bundle exec rake test它时显示的结果与根据教程显示的结果不同.注意:我使用Ubuntu 15.10作为平台.
我击中的结果 $ bundle exec rake test

请指导我如何摆脱错误.
看起来你正在使用RubyDep,这是一个可以帮助你避免不安全的Ruby版本的工具.RubyDep在第一行告诉你:
RubyDep:警告:您的Ruby存在安全漏洞!请升级!(......)
查看堆栈跟踪.../.rbenv/versions/2.2.3/...的其他行的path(),看起来您正在使用随rbenv一起安装的Ruby 2.2.3版.
RubyDep是对的:Ruby中2.2.3存在一个已知的漏洞.
有更新版本的Ruby可用.您可以升级到最新2.2.x版本(或最新版本2.3.x).我建议升级到2.2.5,因为我不知道教程是否兼容2.3.x.
要rbenv按照以下步骤将Ruby升级到更新版本(我想你曾经brew安装过rbenv):
brew update # update to the latest brew version
brew upgrade ruby-build # update Ruby version library
brew upgrade rbenv # update rbenv
rbenv install 2.2.5 # install Ruby 2.2.5
将2.2.5设置为默认的Ruby版本:
rbenv global 2.2.5
更新您的Rails应用程序以使用此Ruby版本.为此,请检查以下文件(如果存在,可能会隐藏它们)并更改该文件中的Ruby版本:
.ruby-version
Gemfile
您可能想要在应用程序根目录中检查您使用的是Ruby的更新版本:
ruby -v # should return `ruby 2.2.5p...`
最后一步是重新安装宝石:
gem install bundler
bundler install
更新是否成功？
