关于 cocoapods 的安装遇到的问题求解

sudo gem install cocoapods

之后出现

ERROR:  While executing gem ... (Errno::EPERM)

Operation not permitted - /usr/bin/pod

错误提示

按照网上各个版本的解答 提示输出如下

sudo gem install -n /usr/local/bin cocoapods

运行后结果如下

Successfully installed cocoapods-0.39.0

Parsing documentation for cocoapods-0.39.0

Installing ri documentation for cocoapods-0.39.0

1 gem installed

然而我执行 pod 命令时仍然提示

-bash: pod: command not found

如此

另外说明 gem -v 2.16.1

ruby -v 2.0.0

实在不知道该怎么处理了 特来求救望各位大神慷慨相助
