无法运行吊舱安装命令

Question

，当我在

$ pod install 

在终端

型我得到这个错误：

[!] Unable to find a specification for SFFocusViewLayout (~> 3.0)

[!] CocoaPods was not able to update the master repo. If this is an unexpected

issue and persists you can inspect it running `pod repo update --verbose

这是我podfile：

# Uncomment this line to define a global platform for your project 
# platform :ios, "8.0" 
# Uncomment this line if you're using Swift 
use_frameworks! 
target "vid starter" do 
pod "SFFocusViewLayout", "~> 3.0" 
end 

target "vid starterTests" do 

end 

有什么错误？

Answer 1

一个暗示是要做的错误建议：pod repo update --verbose，看看它告诉你什么信息。

另一方面，Cocoapods，ruby 2.3和OS X El Capitan似乎都有问题。

如果你已经通过gem安装了Cocoapods，你可以卸载它并通过自制软件重新安装。这固定它对于我来说，这显然是因为自制软件不红宝石2.3使用...

• sudo gem uninstall cocoapods

• brew install cocoapods

我希望这有助于。
