Question

这是我根据{coupapods指南https://guides.cocoapods.org/making/using-pod-lib-create.html用pod lib create创建的cocoapod。为我生成了目录结构和文件以及示例项目。

我的.travis.yml看起来像这样：

# references:
# * https://www.objc.io/issues/6-build-tools/travis-ci/
# * https://github.com/supermarin/xcpretty#usage

osx_image: xcode10.3
language: objective-c
# cache: cocoapods
xcode_workspace: Example/MUXSDKImaListener.xcworkspace
xcode_scheme: MUXSDKImaListener-Example
podfile: Example/Podfile
xcode_sdk: iphonesimulator9.3
before_install:
- gem install cocoapods # Since Travis is not always on latest version
- pod repo update
- pod install --project-directory=Example
script:
- set -o pipefail && xctool test -enableCodeCoverage YES -workspace Example/MUXSDKImaListener.xcworkspace -scheme MUXSDKImaListener-Example -sdk iphonesimulator ONLY_ACTIVE_ARCH=NO | xcpretty
- pod lib lint

当travis尝试构建这些测试时，在安装Cocoapods时会出错。此输出有点令人困惑，因为它似乎说它需要Mux-Stats-AVPlayer 1.0.1，但是它停留了下来，找不到该版本。

该版本存在：https://cocoapods.org/pods/Mux-Stats-AVPlayer

None of your spec sources contain a spec satisfying the dependencies: `Mux-Stats-AVPlayer (= 1.0.1, ~> 1.0.1), Mux-Stats-AVPlayer (~> 1.0.1)`.
You have either:
 * mistyped the name or version.
 * not added the source repo that hosts the Podspec to your Podfile.

似乎在此.travis.yml配置文件中缺少明显的内容。

我不知道为什么示例中的pod安装失败，但是恢复为自动生成的.travis.yml进行了修复。我唯一需要修改的就是在before_install:

下添加说明

pod setup没有这一行-pod lib lint失败，出现特定错误：

错误| [iOS]未知：在验证过程中遇到未知错误（无法找到Mux-Stats-AVPlayer (~> 1.0.0)所依赖的Mux-Stats-Google-IMA的规范）。

gem update concurrent-ruby没有这一行-pod lib lint失败，并出现其他错误：

错误| [iOS]未知：验证期间遇到未知错误（未初始化的常量Concurrent :: Promises）。

所以，这就是我的.travis.yml现在的样子，它运行测试并运行pod lib lint。
