推荐答案

我可以从 VS 获取所有扩展列表，但总是无法获取从 Extensions -> Manage Extensions 或什至从 VS 下载它市场网站.

I am able to get all extension lists from VS, but always unable to download it from Extensions -> Manage Extensions or even from VS marketplace website.

当您单击 VS Extensions Manager UI 中的 更新 按钮时，它实际上是从 VS Marketplace 网站.所以我认为根本原因是您无法从网站下载扩展程序，并且Internet Connection可能有问题.您可以尝试使用 IE 浏览器访问市场网站来检查这一点.

When you click the Update button in VS Extensions Manager UI, it actually downloads the xx.vsix from VS Marketplace website. So I think the root cause is that you can't download the extension from the website, and it could be something wrong with Internet Connection. You can try to access the marketplace website with IE browser to check this point.

我认为这个问题类似于尝试在 .Net 中安装包时出错，可能是哪里出了问题使用您的 DNS 或代理，或者您的防火墙中的设置可能会损坏下载.我想这就是为什么你的互联网很好，但不能很好地访问网站.

I assume this issue is similar to Error caused when trying to Installing package in .Net, it might be something wrong with your DNS or proxy, or maybe the settings in your firewall corrupt the download. I think that's why your Internet is good but can't access the website well.

如果您在短时间内无法解决上网问题，我建议您可以尝试在另一台可以成功访问网站的机器上安装您需要的扩展程序.一个扩展是一个xx.vsix包，你可以从网站上的另一台机器上安装，然后将xx.vsix复制到你当前的机器上，双击它自动安装或更新.(如果它有效，它实际上表明您的互联网出现问题.)

And if you can't resolve the Internet issue in short time, I suggest you can try to install the extension you need by another machine which can access the website successfully. An extension is a xx.vsix package, you can install it from the website by another machine and copy the xx.vsix to your current machine, double-click it to install or update automatically. (And if it works, it actually indicates something is wrong with your Internet.)
