Cocoapods 使用常见错误

1、安装或更新Cocoapods时提示没权限

$ gem install cocoapods
Fetching: cocoapods-core-0.38.2.gem (100%)
ERROR: while executing gem ... (Gem::FilePermissionError)
       You don't have write permissions for the /Library/Ruby/Gems/2.0.0 directory.

解决办法：在命令行前加入 sudo

$ sudo gem install cocoapods
password:
Fetching: cocoapods-core-0.38.2.gem (100%)

2、安装或更新第三方库时提示找不到库

$ pod install
Analyzing dependencies
[!] Unable to find a specification for 'AfNetworking (~> 2.0)'

原因：要么是安装完Cocoapods后没执行pod setup，要么就是pod setup失败

解决办法：清除后，重新 setup，执行以下命令

$ pod repo remove master
$ pod setup

3、安装或更新第三方库时卡主或超慢

$ pod install
Updating local specs repositories

或

$ pod install
Analyzing dependencies

原因：被墙了

解决办法：使用以下命令进行 install 或 update

$ pod install --verbose --no-repo-update
$ pod update --verbose --no-repo-update

4、安装或更新第三方库时出现如下警告

[!] Your Podfile has had smart quotes sanitised. To avoid issues in the future, you should not use TextEdit for editing it. If you are not using TextEdit, you should turn off smart quotes in your editor of choice.

原因：

1、不要使用文本编辑去编辑Podfile文件，使用Xcode编辑，或者使用终端敲命令去编辑。

2、Podfile 的内容语法格式有问题

解决办法：

之后 pod 命令就可以正常使用了
