从 cli: 切换到 cmd 时 Capybara 功能测试失败：

Question

相关信息

• 导轨 4.0.3
• 水豚2.2.1
• guard-livereload 2.2.1
• guard-rspec 4.2.6
• guard-spork 1..5.1
• 守卫茶匙 0.0.4
• phantomjs 1.9.21
• rspec-rails 2.14.4
• spork-rails 4.0.0
• 茶匙 0.7.9

在运行 Guard 时，我看到 cli 选项已被弃用。阅读继任者cmd，并按如下方式实现：

# Before
guard :rspec, after_all_pass: false, cli: '--drb' do
    ...
end

# After
guard :rspec, after_all_pass: false, cmd: 'bundle exec rspec --drb' do
     ...
end

使用更改启动 Guard 后，除了 Capybara 支持的测试（功能）之外的所有测试都失败。在终端中直接运行 bundle exec 控制台会导致所有测试通过。恢复使用 cli 会导致所有测试通过。

任何想法可能是什么问题？

这是我在使用cmd: 'rspec --drb' 时看到的一项测试的输出。

Done.

恢复到cli: '--drb'，测试按预期通过。

好像是DRb support has been removed since guard-rspec 4.0。您可以继续使用guard-rspec 3.1.0，或者（更好地）切换到Zeus 或Spring！
