1.无法连接到网络

2.点击安装和更新无响

 

这两种情况造成的原因都是由于被墙的原因，第一种情况有部分可以通过fq解决，第二种情况是我遇到过的 反正我全局也失败

这里给出一个我自己用过的解决方案

查看控制台日志，中间有这么一段:

[2017-08-30 08:02:22.972] [Info] Downloading from 'https://www.xamarin.com/installer_assets/v3/409bb0941397899e59046bb54cba2bfd5cd9fd76/Mac/Universal/InstallationManifest.xml'.

将中间的网址粘贴到浏览器上面那个打开失败 下面那个可以正常打开，从里面可以查看到每个组件的下载地址

使用工具将组件下载下来安装即可

PS:组件下载地址:
