ios - pod install 在 Jenkins 上给出错误

Question

从安装了 jenkins 的系统运行 pod install 时，它运行良好，但是当我们从 jenkins 运行相同的命令时，它会给出以下错误。我通过添加和删除不同的 pod 来检查特定 pod 是否有错误，但它给出了相同的错误。

```

        end
    end
end
```

我遇到了同样的问题，但不是通过 Jenkins 。
我假设您系统的操作系统与 Jenkins 设置是 El Capitan。

我所做的是，我卸载了 cocoa pod 并安装了最新版本的 Ruby。
首先，我安装了 Homebrew。

Homebrew 带有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

安装最新版本的 Ruby 后，我按照以下步骤安装 CocoaPods

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


gem安装成功后

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