我尝试使用 Fastlane 设置 GitHub Actions 并收到以下错误：

不太确定到底是什么导致了 nil 错误；任何帮助表示赞赏！

您遇到的错误消息“没有将 nil 隐式转换为 String”通常发生在您尝试对 nil 变量执行字符串操作时。在 Fastlane 脚本中，有几个地方使用的环境变量可能为零或为空。让我们检查一下您的脚本并找出潜在的问题：

检查

TEMP_KEYCHAIN_USER
和
TEMP_KEYCHAIN_PASSWORD
：

确保设置了 

TEMP_KEYCHAIN_USER
和 
TEMP_KEYCHAIN_PASSWORD
环境变量且不为零。 确保您已在 GitHub Actions 工作流程中或触发此 Fastlane 脚本的任何位置定义了这些环境变量。 检查 
APPLE_KEY_ID
、
APPLE_ISSUER_ID
和 
APPLE_KEY_CONTENT
：

这些环境变量也应该被定义并且不为零。 验证您为这些环境变量设置的值是否正确。 检查 

DEVELOPER_APP_ID
、
DEVELOPER_APP_IDENTIFIER
和 
PROVISIONING_PROFILE_SPECIFIER
：

确保这些环境变量已设置且不为零。 确认这些值正确并符合您的项目设置。 验证

GIT_AUTHORIZATION
：

确保 

GIT_AUTHORIZATION
已定义且不为零。 确保它包含格式正确的必要凭据。 在试点步骤中检查 ipa：“./your_app_name.ipa”：

确保项目根目录中有一个名为“your_app_name.ipa”的 IPA 文件。如果文件位于不同的目录中，则需要指定正确的路径。 此外，请确保在 GitHub Actions 密钥或环境变量设置中正确定义所有环境变量。仔细检查变量名称中的拼写错误或差异。

通过解决这些问题并确保正确设置所有必需的环境变量，您应该能够使用 Fastlane 解决 GitHub Actions 工作流程中的“没有将 nil 隐式转换为字符串”错误。

此外，当您需要验证它不是 nil 或空时，您可以使用 

to_s
来简化代码，因为如果变量在转换为字符串时为 nil，则直接是空引号 
''
。

UI.message("Debug: Validating keychain variables...")

# e.g
if keychain_password.to_s.empty?
# if keychain_password.nil? || keychain_password.empty?
  UI.error("Error: TEMP_KEYCHAIN_PASSWORD is not set.")
end
