If, for some reason you are unable to update your Visual Studio with the updated TypeScript .exe file (company/business IT policy, non-admin account, etc...), you can try this solution:
如果由于某种原因您无法使用更新的 TypeScript .exe 文件（公司/企业 IT 策略、非管理员帐户等）更新 Visual Studio，您可以尝试以下解决方案：
- Single-click on the "index.d.ts" file in Visual Studio Solution Explorer.
- Look in the Properties panel, under "Build Action".
- Switch it from "TypeScriptCompile" to "Content".
- 在 Visual Studio 解决方案资源管理器中单击“index.d.ts”文件。
- 查看“属性”面板，在“构建操作”下。
- 将其从“TypeScriptCompile”切换到“Content”。
Now, you'll be able to build your project without these errors.
现在，您将能够在没有这些错误的情况下构建您的项目。
Update 2019I have found another workaround/solution that hasn't had any noticeable effects and still allows me to compile without erroring on index.d.ts. Just comment line 68 in your index.d.ts file as such:
2019 年更新我发现了另一个没有任何明显影响的解决方法/解决方案，并且仍然允许我在index.d.ts上编译而不会出错。只需在 index.d.ts 文件中注释第 68 行，如下所示：
//[name: string]: (BaseModifier & Record<string, any>) | undefined;

For Visual Studio 2015:
对于 Visual Studio 2015：
I downloaded TypeScript, installed and restarted Visual Studio. While restarting it prompted me the TypeScript my solution uses is older than what is installed(2.9.2) and whether I want to update it to the supported version, I clicked Yes and that fixed the issue.
我下载了TypeScript，安装并重新启动了 Visual Studio。重新启动时，它提示我我的解决方案使用的 TypeScript 比安装的版本（2.9.2）旧，以及我是否要将其更新到受支持的版本，我单击“是”并解决了该问题。
My guess is TypeScript 2.9.2 is for VS 2017 maybe.
我的猜测是 TypeScript 2.9.2 可能适用于 VS 2017。
