如何在 OS X El Capitan 上安装 ngrok？

Question

首先我尝试从网站下载 ngrok-stable-darwin-amd64.zip。当我尝试通过终端解压缩时，我得到：

Archive:  /Users/User/Downloads/ngrok-stable-darwin-amd64.zip
  End-of-central-directory signature not found.  Either this file is not
  a zipfile, or it constitutes one disk of a multi-part archive.  In the
  latter case the central directory and zipfile comment will be found on
  the last disk(s) of this archive.
unzip:  cannot find zipfile directory in one of /Users/User/Downloads/ngrok-stable-darwin-amd64.zip or
        /Users/User/Downloads/ngrok-stable-darwin-amd64.zip.zip, and cannot find /Users/User/Downloads/ngrok-stable-darwin-amd64.zip.ZIP, period.

使用 Unarchiver 解压缩响应：

读取文件内容时出现问题 “ngrok-stable-darwin-amd64.zip”：数据已损坏

尝试了自制路线brew cask install ngrok，但无济于事：

我正在尝试启用Vagrant share。为什么我不能安装 ngrok，或者更重要的是，我该怎么做？

请，谢谢。

您可以将 ngrok 安装为全局 npm 包。试试这个：

npm install ngrok -g
