CocoaPods 出现LoadError - cannot load such file -- nanaimo错误解决办法

如果经常使用 CocoaPods 进行个人类库的提交和更新，那么肯定会遇到这样的一个错误。如题：LoadError - cannot load such file -- nanaimo，翻译过来就是 LoadError - 无法加载此类文件 - nanaimo。该错误产生的时机一般是在验证 .podspec 文件的时候。具体的错误呈现形式是这样的：

benpaobaodeiMac-2:WZYUnlimitedScrollView bpb$ pod lib lint

上述错误，可以有两种方式进行解决。大家可以分别尝试，总有一种适合你。

方式一，重新安装 CocoaPods 的类库。

先清空 CocoaPods 的缓存：

$ sudo rm -rf ~/.cocoapods/repos/master
$ sudo rm -fr ~/Library/Caches/CocoaPods/ 

再重新安装 CocoaPods 的类库：

$ pod setup 

注意，细心的童鞋可能发现。上面两行清楚缓存的语句不太一样。分别是 rm -rf 和 rm -fr，它们其实是没有区别的，表示强制（f：不提示）删除文件和目录（r：删除）

但方式一可能用起来不会那么顺畅，该错误产生的大多数原因还是应该用方式二来解决。

方式二，对 nanaimo 进行删除并重新加载

$ sudo gem uninstall nanaimo
$ sudo gem install nanaimo

运行上面两行代码的结果：

benpaobaodeiMac-2:WZYUnlimitedScrollView bpb$ sudo gem uninstall nanaimo
Password: 

Select gem to uninstall:
 1. nanaimo-0.2.2
 2. nanaimo-0.2.3
 3. All versions

You have requested to uninstall the gem:
  nanaimo-0.2.3 

xcodeproj-1.4.1 depends on nanaimo (~> 0.2.0)
If you remove this gem, these dependencies will not be met.
