1) algorithm yoga

'algorithm' file not found

'yoga' file not found

解决方法：

在 Podfile 中复制脚本，修改需要手动修改的内容

# 在 Podfile 中加入
def change_lines_in_file(file_path, &change)
  print "Fixing #{file_path}...\n"

  contents = []

  file = File.open(file_path, 'r')
  file.each_line do | line |
    contents << line
  end
  file.close

  File.open(file_path, 'w') do |f|
    f.puts(change.call(contents))
  end
end
