CDN：trunk 相对路径：CocoaPods-version.yml存在

Question

上也报告了问题

所以我正在测试在我的项目中使用 Jest（是运行 RN0.59.10），安装 Enzyme 后一切正常，运行正常。当我将它们合并到我当前的项目（在 RN0.61 上运行）时，解决了一些合并冲突，然后我在 pod install 期间遇到问题。中间可能出了什么问题？

项目在RN0.59中一次又一次设置没有问题，只有当RN0.61带有podfile时才会出现问题。需要指出的一件事是，在集成两个分支之前，我在 RN0.61 上的项目在 pod install.

上运行良好

以下是我尝试克服问题的方法列表，但不幸的是我仍然卡住了。

pod 仓库更新
pod 安装 --repo-update
删除 node_modules + yarn.lock + Pods + Podfile.lock + 再次安装 Yarn 和 pod 安装

登录自 pod install --verbose

Resolving dependencies of `Podfile`
  CDN: trunk Relative path: CocoaPods-version.yml exists! Returning local because checking is only perfomed in repo update
[!] Unable to find a specification for `Firebase/Core (~> 6.9.0)`

You have either:
 * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.
 * mistyped the name or version.
 * not added the source repo that hosts the Podspec to your Podfile.

我的 Podfile 的一部分（这给我带来了问题）：

  # Required by RNFirebase
  pod 'Firebase/Core', '~> 6.9.0'
  pod 'RNFirebase', :path => '../node_modules/react-native-firebase/ios'
  pod 'Fabric', '~> 1.10.2'
  pod 'Crashlytics', '~> 3.14.0'

当我删除上面的 4 行时会发生什么？（这太不对了，我怀疑我的本地有问题）

更新：

我实际上在安装过程中删除了 Podfile.lock。当我恢复到上次成功的状态（podfile.lock 和 yarn.lock 位于我的目录中时），pod 安装成功！

我决定进一步研究这个问题，以下是几个案例场景的结果。

去掉podfile.lock，显示如下：

[!] Unable to find a specification for `Firebase/Core (~> 6.9.0)`

You have either:
 * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.
 * mistyped the name or version.
 * not added the source repo that hosts the Podspec to your Podfile.

去掉yarn.lock，显示如下：

[!] CocoaPods could not find compatible versions for pod "FBSDKCoreKit":
  In snapshot (Podfile.lock):
    FBSDKCoreKit (= 5.7.0, ~> 5.0, ~> 5.5)

  In Podfile:
    react-native-fbsdk (from `../node_modules/react-native-fbsdk`) was resolved to 1.1.1, which depends on
      react-native-fbsdk/Core (= 1.1.1) was resolved to 1.1.1, which depends on
        FBSDKCoreKit (= 5.8)


You have either:
 * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.
 * changed the constraints of dependency `FBSDKCoreKit` inside your development pod `react-native-fbsdk`.
   You should run `pod update FBSDKCoreKit` to apply changes you've made.

同时删除 yarn.lock + podfile.lock，显示如下：

[!] Unable to find a specification for `Firebase/Core (~> 6.9.0)`

You have either:
 * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.
 * mistyped the name or version.
 * not added the source repo that hosts the Podspec to your Podfile.

Answer 1

TLDR;

将 source 'https://cdn.cocoapods.org/' 附加到 Podfile（在目标 'projectName' 之前）

终于找到了根本原因并找到了解决方案！原因是，我的 podfile 中有一个 privateRepo，它覆盖了从 Cocoapods 获取 podspecs 的默认来源。错误示例如下

# Uncomment the next line to define a global platform for your project
platform :ios, '9.0'
require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules'
source 'https://github.com/privateRepo/Specs.git'

target 'project' do
  # Comment the next line if you don't want to use dynamic frameworks
  # use_frameworks!
.....
....
...
..
.
end

因此，指向回 Cocoapods' CDN 的简单解决方案将解决问题。

# Uncomment the next line to define a global platform for your project
platform :ios, '9.0'
require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules'
source 'https://github.com/privateRepo/Specs.git'

# Pointing back the source to cocoapod's CDN for retrieving specs.
# Was overwritten by privateRepo/Specs.git on earlier lines
source 'https://cdn.cocoapods.org/'

target 'project' do
  # Comment the next line if you don't want to use dynamic frameworks
  # use_frameworks!
.....
....
...
..
.
end
