新生成的Guardfile为空

Question

我正在尝试在一个带有一些 Ruby 文件和 RSpec 测试的小型 Rub​​y 中创建一个 Guardfile。这不是 Rails 项目。

当我运行 gem install guard 时，我得到以下信息：

$ gem install guard
Fetching: listen-1.3.1.gem (100%)
Successfully installed listen-1.3.1
Fetching: lumberjack-1.0.4.gem (100%)
Successfully installed lumberjack-1.0.4
Fetching: guard-1.8.3.gem (100%)
Successfully installed guard-1.8.3
Installing ri documentation for listen-1.3.1
Installing ri documentation for lumberjack-1.0.4
unable to convert "\xCF" from ASCII-8BIT to UTF-8 for bin/fsevent_watch_guard, skipping
Installing ri documentation for guard-1.8.3
3 gems installed

显然“\xCF”应该已经安装，但它没有。我无法弄清楚这是什么，以及它是否可能是我的问题的原因。

后来，当我尝试为 RSpec 测试创建保护时，会发生以下情况：

$ guard init rspec
19:45:11 - INFO - Writing new Guardfile to /home/kathryn/demo3/Guardfile
19:45:11 - ERROR - Could not load 'guard/rspec' or '~/.guard/templates/rspec' or find class Guard::Rspec

正如 INFO 建议的那样，创建了一个新的 Guardfile，但它充满了一条说明，指示我查看 gem 的 README，而不是 RSpec 的守卫。如果我手动为RSpec添加保护，然后尝试运行guard，结果是：

$ guard
19:41:03 - ERROR - Could not load 'guard/rspec' or find class Guard::Rspec
19:41:03 - ERROR - cannot load such file -- guard/rspec
19:41:03 - ERROR - Invalid Guardfile, original error is:
> [#] undefined method `new' for nil:NilClass
19:41:03 - ERROR - No guards found in Guardfile, please add at least one.
19:41:03 - INFO - Guard is using NotifySend to send notifications.
19:41:03 - INFO - Guard is using TerminalTitle to send notifications.
19:41:04 - INFO - Guard is now watching at '/home/kathryn/demo3'

我看到 gem 找不到它需要的一些文件，但我不确定从这里去哪里。这是我第一次使用守卫。任何帮助表示赞赏。

这是我当前的 Guardfile：

guard :rspec do
  watch(%r{^spec/.+_spec\.rb$})
  watch(%r{^lib/(.+)\.rb$}) { |m| "spec/lib/#{m[1]}_spec.rb" }
  watch('spec/spec_helper.rb') { "spec" }
end

这不是自动生成的。当我第一次创建Guardfile时，内容是：

# A sample Guardfile
# More info at https://github.com/guard/guard#readme

我在此处添加了作为标准 RubyGem 项目保护的 RSpec 保护：https://github.com/guard/guard-rspec。 （需要说明的是，我没有使用那个宝石。它只是一个容易找到守卫的地方。）

一旦安装了guard-rspec gem，它应该“正常工作”。

我正在执行以下步骤以使其干净地加载：

▶ gem install guard-rspec rspec

完成后，我执行以下命令：

▶ guard init rspec
00:55:13 - INFO - rspec guard added to Guardfile, feel free to edit it

我的 Guardfile 看起来像这样：

# A sample Guardfile
# More info at https://github.com/guard/guard#readme

guard :rspec do
  watch(%r{^spec/.+_spec\.rb$})
  watch(%r{^lib/(.+)\.rb$})     { |m| "spec/lib/#{m[1]}_spec.rb" }
  watch('spec/spec_helper.rb')  { "spec" }

  # Rails example
  watch(%r{^app/(.+)\.rb$})                           { |m| "spec/#{m[1]}_spec.rb" }
  watch(%r{^app/(.*)(\.erb|\.haml|\.slim)$})          { |m| "spec/#{m[1]}#{m[2]}_spec.rb" }
  watch(%r{^app/controllers/(.+)_(controller)\.rb$})  { |m| ["spec/routing/#{m[1]}_routing_spec.rb", "spec/#{m[2]}s/#{m[1]}_#{m[2]}_spec.rb", "spec/acceptance/#{m[1]}_spec.rb"] }
  watch(%r{^spec/support/(.+)\.rb$})                  { "spec" }
  watch('config/routes.rb')                           { "spec/routing" }
  watch('app/controllers/application_controller.rb')  { "spec/controllers" }

  # Capybara features specs
  watch(%r{^app/views/(.+)/.*\.(erb|haml|slim)$})     { |m| "spec/features/#{m[1]}_spec.rb" }

  # Turnip features and steps
  watch(%r{^spec/acceptance/(.+)\.feature$})
  watch(%r{^spec/acceptance/steps/(.+)_steps\.rb$})   { |m| Dir[File.join("**/#{m[1]}.feature")][0] || 'spec/acceptance' }
end

当我执行guard start 命令时，这些错误不会显示：

▶ guard start
00:57:08 - INFO - Guard uses NotifySend to send notifications.
00:57:08 - INFO - Guard uses Tmux to send notifications.
00:57:08 - INFO - Guard uses TerminalTitle to send notifications.
00:57:09 - INFO - Guard::RSpec is running
