找到了满足`app_settings（来自`.symlinks/plugins/app_settings/ios`）`依赖项的规格，但它们需要更高的最低部署

Question

我为我的 Flutter 应用程序运行

pod install

，我收到此错误：

[!] CocoaPods could not find compatible versions for pod "app_settings":
  In Podfile:
    app_settings (from `.symlinks/plugins/app_settings/ios`)

Specs satisfying the `app_settings (from `.symlinks/plugins/app_settings/ios`)` dependency were found, but they required a higher minimum deployment target.

Answer 1

我通过运行

flutter precache --ios

修复了它。

Answer 2

如果您检查 app_settings 的 pubspec，它会提到 15 是最小部署目标。所以我在我的 podfile 中将其更改为 15 并且它起作用了

#
# To learn more about a Podspec see http://guides.cocoapods.org/syntax/podspec.html
#
Pod::Spec.new do |s|
  s.name             = 'app_settings'
  s.version          = '3.0.0+1'
  s.summary          = 'A Flutter plugin for opening iOS and Android phone settings from an app.'
  s.description      = 'A Flutter plugin for opening iOS and Android phone settings from an app.'
  s.homepage         = 'https://github.com/spencerccf/app_settings'
  s.license          = { :file => '../LICENSE' }
  s.author           = { '[email protected]' => '[email protected]' }
  s.source           = { :path => '.' }
  s.source_files = 'Classes/**/*'
  s.public_header_files = 'Classes/**/*.h'
  s.dependency 'Flutter'

  s.ios.deployment_target = '15.0'
  s.swift_version = '5.0.1'
end
