swift - 遇到未知错误(CocoaPods 找不到 pod 的兼容版本

Question

我正在创建一个 pod。linting 时出现此错误:pod spec lint TrackerExample.podspec --no-clean --use-libraries

我距离 pod 验证有 1 个错误。您能否帮助找出缺少的内容或需要修改的内容。

这是我的podspec:

Pod::Spec.new do |spec|
  spec.name         = "TrackerExample"
  spec.version      = "0.0.1"
  spec.license      = "Copyright ****"
  spec.homepage     = "https:// *****"
  spec.author       = { "*****" => "*******" }
  spec.summary      = "some description"
  spec.source   = { :git => "******t" }  
  spec.source_files  = "TrackerExample/*.{h,m}"
  spec.ios.deployment_target = "9.0"
  spec.osx.deployment_target = "10.10"
  spec.swift_version = '4.0'
  spec.dependency 'MatomoTracker', '5.2'
  spec.subspec 'MatomoTracker' do |lib|
    lib.dependency 'MatomoTracker', '5.2'
    lib.source_files = "Pods/MatomoTracker/MatomoTracker/*.{h,m,swift}"
  end
end

而且，这是终端输出。我收到以下错误:

ERROR | [OSX] unknown: Encountered an unknown error (CocoaPods could not find compatible versions for pod "MatomoTracker":

Pods workspace available at `/var/folders/n8/9jmhgp1x2hxgg7_r4ryvs7tcn166k1/T/CocoaPods-Lint-20180821-86279-qyai9s-TrackerExample/App.xcworkspace` for inspection.

Analyzed 1 podspec.

[!] The spec did not pass validation, due to 1 error and 4 warnings.

与 podfile 相关的东西。不过，我确实将 pod 版本指定为 5.2。为什么这与我自己的 pod 的版本 0.0.1 冲突？

仅供引用，这是我正在使用的“MatomoTracker”依赖项的 podfile

# Uncomment the next line to define a global platform for your project
platform :ios, '9.0'

target 'TrackerExample' do
  # Comment the next line if you're not using Swift and don't want to use dynamic frameworks
  use_frameworks!

  # Pods for TrackerExample
  pod 'MatomoTracker', '~> 5.2'
end

Answer 1

如果您在运行 pod spec lint 的同一目录中创建一个名为 .swift-version 的文件，其中包含您需要的版本(例如“4.0”)echo "4.0"> .swift-版本

它可能会解决您的问题。

也只需执行以下步骤:-

1. pod 解体
2. pods 安装
3. pod 更新(如果有必要，请执行其他操作，如果您拥有所有最新的 pod，请不要使用它。)
