Question

我正在使用cocoapods 1.7.5，执行pod install时遇到此错误：

[!] Invalid `Podfile` file: undefined method `+' for nil:NilClass.
 #  from /Users/yuhan/jiemian_project/iOS_MoerFinance/A-源代码/MoerFinance/Podfile:71
 #  -------------------------------------------
 #    location = flutter_podhelper.index(post_install_string)
 >    location += post_install_string.length
 #    
 #  -------------------------------------------

以前有人遇到过同样的问题吗？我不知道为什么flutter_podhelper.index(post_install_string)返回nil，我可以在目录中找到podhelper。在另一台计算机上，pod install是成功的，但是在这台计算机上，显示上面的错误。

podfile一些代码

def multiple_post_install(flutter_application_path)
  #read podhelper from flutter_application_path
  flutter_podhelper = File.read(File.join(flutter_application_path, '.ios', 'Flutter', 'podhelper.rb'))

  #find the post_install end location by hardcoding
  post_install_string = 'post_install do |installer|'
  location = flutter_podhelper.index(post_install_string)
  location += post_install_string.length
