我一直在使用 cocoa pods 并安装 fireBase 时出错

I keep getting an error with cocoa pods and installing fireBase

enter image description here

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

target 'Crystal' do
  # Comment the next line if you don't want to use dynamic frameworks
  use_frameworks!

  # Pods for Crystal
  # add the Firebase pod for Google Analytics
pod 'Firebase/Analytics'
pod 'Firebase/Auth'
pod 'Firebase/Database'
pod 'Firebase/Storage


end


//error yanesrosenskrabe@MacBook-Pro-de-Yanes Crystal % pod install

您的 podFile 中有错字

pod 'Firebase/Storage

缺少结尾引号

pod 'Firebase/Storage'

使用 Cocoapods 应用程序或终端中的 pico 编辑器编辑您的 podfile 也是一个好主意,这样您就不会不小心添加任何奇怪或不可见的字符。
