Ios 在Jenkins上出现pod安装错误

当从安装了jenkins的系统运行pod安装时，它运行良好，但是当我们从jenkins运行相同的命令时，它给出以下错误。我已经通过添加和删除不同的pod进行了检查，以检查特定pod是否存在错误，但它给出了相同的错误

我遇到了同样的问题，但不是通过詹金斯。 我认为你的系统的操作系统和詹金斯设置是El Capitan

我所做的是，我卸载了可可豆并安装了最新版本的Ruby。 首先，我安装了自制软件

Homebrew附带了一个非常简单的安装脚本。当它要求您安装XCode命令行工具时，请说“是”

打开终端并运行以下命令：

ruby -e "$(curl -fsSL    https://raw.githubusercontent.com/Homebrew/install/master/install)" 

之后，我使用rbenv安装了Ruby 2.3.1

brew install rbenv ruby-build
rbenv install 2.3.1
rbenv global 2.3.1ruby -v

在安装了最新版本的Ruby之后，我按照以下步骤安装CoCoapod

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


在gem成功安装之后

$ export PATH=$PATH:/Library/Ruby/bin
