我使用chruby来管理我的Ruby版本,以及Bundler的binstubs以避免输入"捆绑exec"。我遇到了一些我不太了解的问题。这是我在我们的(Rails 4,Ruby 2.2.2)应用程序中运行测试套件时得到的结果:
$ rspec

当我运行$ bundle exec rspec
时,套件运行正常。我一直在研究后现代的gem_home,并安装了它,但它没有给我我想要的结果。我在OSX Yosemite上使用zsh。
source /usr/local/share/chruby/chruby.sh
source '/usr/local/share/chruby/auto.sh'
source /usr/local/share/gem_home/gem_home.sh
export PATH=./.bundle/bin:$PATH
alias b='bundle install --path .bundle/gems --binstubs .bundle/bin'
答案 0 :(得分:2)
只需在系统中安装simplecov
gem(只需执行:gem install simplecov
)并再次运行测试。它会起作用。
但是,使用bundle exec
运行rake或rspec命令是一种更好的做法。因此,您可以确保命令在Gemfile
。
您可以将这些别名添加到.zshrc
文件中:
alias ber="bundle exec rspec"
alias be="bundle exec"
然后,运行你的rspec测试:
ber
,或者
be rspec
答案 1 :(得分:0)
您的问题是,bundler已在项目本地安装了simplecov
,并且您正在尝试运行全局系统rspec
。这将在系统ruby库位置中查找simplecov
。使用Ruby语言版本管理器不会改变这种行为。它只会使用版本化的ruby库位置。
如果您希望您的版本化Ruby一起使用rspec
和simplecov
,那么您需要使用提供的simplecov
等效工具在版本化的ruby中安装gem
我不确定为什么你会发现运行bundle exec
非常重要。您可以随时在.bashrc
或.bash_profile
中创建别名。我有两个bundle exec,一个是be
,另一个是bexec
。我还有bundle exec rails
(brails
)和bundle exec rake
(break
)的别名。在实践中,我发现这些与运行常规命令几乎没有什么不同。
