如何在Mac OS X上安裝 Ruby運(yùn)行環(huán)境
ex:
The dependency `` is not used in any concrete target
The dependency AFNetworking

CocoaPods再遇困難,前幾天電腦重裝了系統(tǒng),所有的開發(fā)工具就都裝了最新的,當(dāng)我用CocoaPods的時(shí)候,出了一個(gè)提示,大概就是我的版本不是 last version,然后給你提示了一個(gè)命令,直接復(fù)制即可,就是下面這個(gè):
sudo gem install cocoapods --pre
安裝cocoapods的預(yù)覽版本,就會(huì)更新下來新的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
很高興啊,更新了新的版本,然而pod install就出錯(cuò)了,悲了個(gè)劇!出錯(cuò)如下:
Updating local specs repositories

我用的三方庫(kù)比較多,挺長(zhǎng)的,出這個(gè)錯(cuò)是告訴我們我們所用的庫(kù)沒有指定target,它不知道用在哪里,所以就給報(bào)錯(cuò)了,然后我去了cocoapods的官網(wǎng)看了下,cocoapods官網(wǎng)地址
官網(wǎng)是這樣給推薦的:
在創(chuàng)建Podfile的時(shí)候,用這種格式使用,
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 記得替換為自己攻城里面的target。這樣就基本OK了,執(zhí)行pod install / pod update 就都可以了。
如果提示Permission denied @ rb_sysopen - /Users/John_LS/.gemrc這個(gè)錯(cuò)誤,那說明沒有權(quán)限。
原因:我已經(jīng)更新了我的rubygem像這樣的gem update --syste,但是,只有我當(dāng)?shù)氐膅ems被更新。由于gem: --user-install安裝限制在我的/etc/.gemrc。當(dāng)工作時(shí),它使用全局rubygem與我無關(guān)。
解決方法:要解決這個(gè)問題,我更新了全局的RubyGems:sudo gem update --system --no-user-install.。
