【问题描述】：

我正在尝试添加一个 if 语句来“交付”fastlane 的操作。

我将 fastlane 与 bitrise 一起使用，我遇到的问题是，当我将 if 语句添加到工作语句时，它总是抛出以下语法错误：“”

这是我拥有的 Fastfile 的代码：

default_platform(:ios)

platform :ios do
  desc "TEST"
    lane :testEnv do

        deliver(
            app_version: ENV['APP_VERSION'],

这是我完整的 Fastfile，问题是在我的项目中，我们有很多针对不同客户的目标，每个目标都使用不同的语言。我所做的是将这些信息保存在 bitrise 机器上的环境变量（它们在 bitrise yml 上定义）。

如您所见，我正在尝试根据环境变量添加不同的语言，如果存在也编写这种语言，但它不起作用。我不完全知道问题出在哪里，因为当我没有 ifs 时，它就像这个例子一样工作：

description: 
                "es-ES" => ENV['DESCRIPTION_ES'],
                "en-GB" => ENV['DESCRIPTION_EN'],
                "pt-BR" => ENV['DESCRIPTION_PT'],
                "zh-Hans" => ENV['DESCRIPTION_ZH'],
                "ca" => ENV['DESCRIPTION_CA'],
        ,

这段代码可以正常工作。

我对 ruby​​ 语法了解不多，所以也许在你的帮助下我可以做到这一点，这会节省我很多时间。

谢谢！

【问题讨论】：

请确保构造一个minimal reproducible example。请注意，所有这三个词都很重要：它应该只是一个示例，您不应该发布整个实际代码，而应该创建一个简化的示例来演示您的问题。此外，它应该是minimal，即它不应该包含证明问题所必需的任何内容。 （大多数初学者问题可以用不到 5 行简单的代码来演示。）而且它应该是reproducible，这意味着如果我复制并粘贴并运行代码，我应该会看到与您完全相同的问题见。

嗨@JörgWMittag，也许这几行就足够了：如果ENV['DESCRIPTION_ES'] != nil "es-ES" => ENV['DESCRIPTION_ES']，结束我使用这个网页@ 987654324@查看错误

【参考方案1】：

很遗憾，这是无效的 ruby​​ 语法：

  if ENV['RELEASE_NOTES_ES'] != nil
    "es-ES" => ENV['RELEASE_NOTES_ES'],
  end

有several ways you could add conditional elements to a hash in ruby，如：

.tap do |my_hash| 
  my_hash[:a] = 'a'
  my_hash[:b] = 'b' if condition
end

或者：

:a => 'a'.merge( condition ? :b => 'b' :  )

或者：

hash =  a: 'a', b: 'b' 
hash[:c] = 'c' if condition

...但是对于您的用例，由于您要做的只是删除具有nil 值的哈希元素，因此我将使用Hash#compact：

release_notes: 
  "es-ES" => ENV['RELEASE_NOTES_ES'],
  "en-GB" => ENV['RELEASE_NOTES_EN'],
  "pt-BR" => ENV['RELEASE_NOTES_PT'],
  "zh-Hans" => ENV['RELEASE_NOTES_ZH'],
  "ca" => ENV['RELEASE_NOTES_CA']
.compact

是的，这正是我所需要的，非常感谢！！
