pod spec lint:尝试读取不存在的文件夹

试图lint一个本地 pod规范

$ pod spec lint MyPod.podspec

我越来越

[!]尝试读取不存在的文件夹/private/tmp/CocoaPods/Lint/Pods/MyPod.

我检查/private/tmp/CocoaPods/Lint/Pods/了我确实找不到我的podspec的地方,
但我找到了它/private/tmp/CocoaPods/Lint/Pods/Local Podspecs/

是什么导致这种情况和/或我如何调试？

有关信息,这是我的pod规格

Pod::Spec.new do |s|
    s.name         = "MyPod"
    s.version      = "0.0.1"
    s.summary      = "A pretty cool pod"
    s.author       = { "Me" => "me@home.net" }
    s.license      = 'MIT'
    s.homepage     = "http://www.mypod.net"
    s.source       = { :path => "." }
    s.source_files = '*.{h,m}'
    s.platform     = :ios, '6.0'
    s.requires_arc = true
end
