我如何安装我的gemfile，它给出错误？

Question

这是我的gem文件：

source "https://rubygems.org"
gem 'fastlane'
gem 'cocoapods'
gem ‘CFPropertyList' gem ‘slather'

plugins_path = File.join(File.dirname(__FILE__), 'fastlane', 'Pluginfile')
eval_gemfile(plugins_path) if File.exist?(plugins_path)

这是我收到的错误信息：

[!] There was an error parsing `Gemfile`: Undefined local variable or method `‘CFPropertyList' for Gemfile. Bundler cannot continue.

 #  from /Users/jordyhuijgens/Desktop/project folder/BwLidar/Gemfile:5
 #  -------------------------------------------
 #  gem 'cocoapods'
 >  gem ‘CFPropertyList' gem ‘slather'
 #  
 #  -------------------------------------------

我正在尝试为我的IOS应用程序安装Travis CI。

输入行每个依赖项

source "https://rubygems.org"

gem 'fastlane'
gem 'cocoapods'
gem 'CFPropertyList' 
gem 'slather'

plugins_path = File.join(File.dirname(__FILE__), 'fastlane', 'Pluginfile')
eval_gemfile(plugins_path) if File.exist?(plugins_path)
