ruby-on-rails – 捆绑exec rake测试投掷错误

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测试时,它会显示一些不同于它应该按照教程显示的结果.
注意：我使用Ubuntu 15.10作为平台.

当我点击$bundle exec rake test时的结果

解决方法

看起来你正在使用 RubyDep,这个工具可以帮助你避免不安全的Ruby版本. RubyDep在第一行告诉你：

RubyDep: WARNING: your Ruby has security vulnerabilities! Please upgrade! (…)

查看堆栈跟踪的其他行的路径(… / .rbenv / versions / 2.2.3 / …),看起来您使用的是使用rbenv安装的Ruby 2.2.3版.

RubyDep是对的：有一个 known vulnerability in Ruby 2.2.3.

有newer versions of Ruby可用.您可以升级到最新的2.2.x版本(或最新的2.3.x).我建议升级到2.2.5,因为我不知道该教程是否与2.3.x兼容.

要使用rbenv将Ruby升级到更新版本,请按照以下步骤操作(我假设您使用brew安装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？

bundle exec rake test
