错误
- 错误类型 1：
[!] Invalid `Podfile` file: syntax error, unexpected ',', expecting end-of-input
'FMDB','~>2.6.2'
[!] Invalid `Podfile` file: syntax error, unexpected tSTRING_BEG, expecting end-of-input
platform:ios'8.0'
[!] The dependency `FMDB (~> 2.6.2)` is not used in any concrete target.
[!] Invalid `Podfile` file: syntax error, unexpected end-of-input, expecting keyword_end.
错误原因：podfile的配置不对，正确的配置如下：
platform :ios, '8.0'
target "no_name" do
pod 'FMDB', '~> 2.6.2'
end
注：标点和空格 一定要正确
- 错误类型 2:
[!] Unable to satisfy the following requirements:
`FMDB (~> 2.6.2)` required by `Podfile`
None of your spec sources contain a spec satisfying the dependency: `FMDB (~> 2.6.2)`.
You have either:
* out-of-date source repos which you can update with `pod repo update`.
* mistyped the name or version.
* not added the source repo that hosts the Podspec to your Podfile.
Note: as of CocoaPods 1.0, `pod repo update` does not happen on `pod install` by default.
执行下面命令
sudo gem install cocoapods --pre
报错

####CocoaPods常用命令
1. pod install
根据Podfile文件指定的内容，安装依赖库，如果有Podfile.lock文件而且对应的Podfile文件未被修改，则会根据Podfile.lock文件指定的版本安装。
每次更新了Podfile文件时，都需要重新执行该命令，以便重新安装Pods依赖库。
2. pod update
若果Podfile中指定的依赖库版本不是写死的，当对应的依赖库有了更新，无论有没有Podfile.lock文件都会去获取Podfile文件描述的允许获取到的最新依赖库版本。
3. pod search <第三方库>
4. pod --version 查看版本
5. sudo gem uninstall cocoapods 卸载cocoapods
