我正在尝试在我的swift项目中安装Alamofire 4.4，而我正在从指定的链接(https://github.com/Alamofire/Alamofire)中迈出一步，但我正面临着这个问题:-。

[!] Unable to satisfy the following requirements:

- `Alamofire (~> 4.4)` required by `Podfile`

None of your spec sources contain a spec satisfying the dependency: `Alamofire (~> 4.4)`.

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 * out-of-date source repos which you can update with `pod repo update`.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

Note: as of CocoaPods 1.0, `pod repo update` does not happen on `pod install` by default.

I have in in my System : Mac os : 10.12.2 x_code version : 8.2.1 swift version : 3.0.2

我的系统中有:Mac os: 10.12.2 x_code版本:8.2.1 swift版本:3.0.2。

pod File configuration :

豆荚文件配置:

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

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

  # Pods for testAlarmofireAndswiftyJson
  pod 'Alamofire', '~> 4.4'
end

I am stucking here please help.

我在这里学习，请帮忙。

4 个解决方案

#1

Execute the follwoing on your terminal

在你的终端上执行下面的操作。

sudo gem install cocoapods --pre

Then change pod file configuration to '9.0' to '10.0'

然后将pod文件配置更改为'9.0'到'10.0'

platform :ios, '10.0'

target 'project_name' do
    pod 'Alamofire', '~> 4.4'
end

After changing the podfile configuration open terminal and go to project path. Then execute following

在更改了podfile配置后，打开终端并进入项目路径。然后执行后

'pod install'

#2

You need to add a source statement to your Podfile so CocoaPods knows where to search for the pods you're referencing. You likely want this at the top of your Podfile:

您需要向您的Podfile添加一个源语句，这样CocoaPods就知道在哪里搜索您所引用的pods。你可能想要这个在你的播客顶部:

source 'https://github.com/CocoaPods/Specs.git'

#3

CocoaPods 1.1.0+ is required to build Alamofire 4.0.0+.

CocoaPods 1.1.0+被要求建立Alamofire 4.0.0+。

To update CocoaPods you simply install the gem again

要更新CocoaPods，您只需再次安装gem。

$ [sudo] gem install cocoapods

Or for a pre-release version

或者是预发布版本。

$ [sudo] gem install cocoapods --pre

And then try again

然后再试一次

Podfile:

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

target '02-Weibo' do
    # Comment the next line if you're not using Swift and don't want to use dynamic frameworks
    use_frameworks!

    # Pods for 02-Weibo

       pod 'Alamofire', '~> 4.4'
       pod 'SnapKit', '~> 3.2.0'
