pod规格

# Be sure to run `pod lib lint <libraryName>.podspec' to ensure this is a
# valid spec before submitting.
#
# Any lines starting with a # are optional,but their use is encouraged
# To learn more about a podspec see https://guides.cocoapods.org/syntax/podspec.html
#

pod::Spec.new do |s|
  s.name             = '<libraryName>'
  s.version          = '0.1.0'
  s.summary          = 'A short description of < libraryName >'
  s.module_name      = '< libraryName >'

# This description is used to generate tags and improve search results.
#   * Think: What does it do? Why did you write it? What is the focus?
#   * Try to keep it short,snappy and to the point.
#   * Write the description between the DESC delimiters below.
#   * Finally,don't worry about the indent,Cocoapods strips it!

  s.description      = <<-DESC
TODO: Add long description of the pod here.
                       DESC

  s.homepage         = '<url>'
  # s.screenshots     = 'www.example.com/screenshots_1','www.example.com/screenshots_2'

是否缺少任何配置？

顺便说一句，我尝试使用pod lib create创建一个Freshs库仍然存在这个问题：D
