ruby-on-rails - 找不到命令/使用自动测试安装带有 'bundle install' 的缺少的 gem 二进制文件

Question

我对 RoR 完全陌生。我正在关注 Michael Hartl 的书。我无法进行自动测试。请提出问题所在以及解决方法。

当我在 Rails 项目目录中的命令行中运行“autotest”时，我得到以下信息:

-bash: autotest: command not found

当我运行“bundle exec autotest”时，我得到以下信息:

 bundler: command not found: autotest
 Install missing gem binaries with `bundle install'

这是 Gemfile

source 'http://rubygems.org'

gem 'rails', '3.0.3'
gem 'sqlite3-ruby', :require => 'sqlite3'

group :development do
gem 'autotest'
gem 'rspec-rails', '2.4.1' 
end

group :test do
gem 'rspec', '2.4.0'
gem 'webrat', '0.7.1'
end

这是 'gem list' 的输出

Answer 1

bundle install --binstubs 会将您的包中的所有可执行文件安装到项目的本地 bin 目录中(请参阅 http://gembundler.com/ )，然后您可以运行 ./bin/autotest 。
