CocoaPods报错:The dependency `AFNetworking ` is not used in any concrete target或者Permission denied @ rb_sysopen - /Users/John_LS/.gemrc

如何在Mac OS X上安装 Ruby运行环境

CocoaPods 的安装和使用

ex:

The dependency `` is not used in any concrete target

The dependency AFNetworking is not used in any concrete target

CocoaPods再遇困难,前几天电脑重装了系统,所有的开发工具就都装了最新的,当我用CocoaPods的时候,出了一个提示,大概就是我的版本不是 last version,然后给你提示了一个命令,直接复制即可,就是下面这个:

sudo gem install cocoapods --pre

安装cocoapods的预览版本,就会更新下来新的1.0.0.beta.2版本,如下所示:

Successfully installed cocoapods-1.0.0.beta.2

Parsing documentation for cocoapods-1.0.0.beta.2

很高兴啊,更新了新的版本,然而pod install就出错了,悲了个剧!出错如下:

我用的三方库比较多,挺长的,出这个错是告诉我们我们所用的库没有指定target,它不知道用在哪里,所以就给报错了,然后我去了cocoapods的官网看了下,cocoapods官网地址

官网是这样给推荐的:

在创建Podfile的时候,用这种格式使用,

platform :ios, '8.0'

use_frameworks!

target 'MyApp' do

pod 'AFNetworking', '~> 2.6'

pod 'ORStackView', '~> 3.0'

pod 'SwiftyJSON', '~> 2.3'

end

里面的 MyApp 记得替换为自己攻城里面的target。这样就基本OK了,执行pod install / pod update 就都可以了。

如果提示Permission denied @ rb_sysopen - /Users/John_LS/.gemrc这个错误,那说明没有权限。

原因:我已经更新了我的rubygem像这样的gem update --syste,但是,只有我当地的gems被更新。由于gem: --user-install安装限制在我的/etc/.gemrc。当工作时,它使用全局rubygem与我无关。

解决方法:要解决这个问题,我更新了全局的RubyGems:sudo gem update --system --no-user-install.。
