安装 pod 时，错误“无效的 `Podfile` 文件：未定义的方法 `plateform'

Question

我是一个新的 ios 开发者，我需要安装“AFNetworking”。

首先，我已经安装了 cocoapods；

其次，我在我的文字空间中创建了一个“Podfile”；

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '8.0'
pod 'AFNetworking'

然后，我跑 pod install 有一个错误：

/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/pathname.rb:422:in `open': No such file or directory - /Users/nemo/.cocoapods/repos (Errno::ENOENT)

Answer 1

看起来好像 CocoaPods 没有正确安装在您的系统上。

看看这个回复：

Cocoapods commands fail due to "No such file or directory @ dir_initialize - /Users/<username>/.cocoapods/repos (Errno::ENOENT)"

尝试“pod setup”，然后“pod install”。

Answer 2

第二行：plateform :ios, '8.0' 拼写错误。应该是：platform :ios, '8.0'
