pod》error:The dependency `` is not used in any concrete target

内容提要:

  podfile升级之后到最新版本,pod里的内容必须明确指出所用第三方库的target,否则会出现The dependency `` is not used in any concrete target这样的错误。

以下从三个步骤陈述:

1. Podfile升级

查看pod版本:

pod --version

pod 升级(此时是升级到1.0.0.beta.2版本):

sudo gem install cocoapods --pre

2. 错误内容:

我的Podfile的内容是:

platform :ios, '7.0'

pod 'ReactiveCocoa', '2.1.8'
pod 'objectiveflickr', '2.0.4'
pod 'LinqToObjectiveC', '2.0.0'
pod 'SDWebImage', '3.6'

pod install后出现错误The dependency `` is not used in any concrete target

pod install
/System/Library/Frameworks/Ruby.framework/Versions//universal-darwin14/rbconfig.rb:: warning: Insecure world writable
Re-creating CocoaPods due to major version update.
Updating local specs repositories
Analyzing dependencies
[!] The dependency `ReactiveCocoa (= 2.1.8)` is not used in any concrete target.
The dependency `objectiveflickr (= 2.0.4)` is not used in any concrete target.
The dependency `LinqToObjectiveC (= 2.0.0)` is not used in any concrete target.
The dependency `SDWebImage (= 3.6)` is not used in any concrete target.

3. 修改方法:

Podfile内容更改:

platform :ios, '7.0'

target "RWTFlickrSearch" do
pod 'ReactiveCocoa', '2.1.8'
pod 'objectiveflickr', '2.0.4'
pod 'LinqToObjectiveC', '2.0.0'
pod 'SDWebImage', '3.6'
end

这样再运行pod install,就会成功了。
