Have you tried running tsc --init in your directory? This will create a tsconfig.json file in your directory where you can define your configuration. VSCode will also start using this file once it finds it in your root directory.

你试过在你的目录中运行tsc -init吗?这将创建一个tsconfig。可以在目录中定义配置的json文件。VSCode在根目录中找到这个文件后也将开始使用它。

Check out tsconfig.json documentation for more details.

查看tsconfig。有关更多细节的json文档。

I had a similar issue and didn't even showed the version of Typescript after typing tsc -v. Even i had to scratch my head for few days and couldn't solve it.

我也遇到过类似的问题，在输入tsc -v之后，我甚至没有显示打字稿的版本。就连我也得挠挠头几天也解决不了。

At last i did 4 things.

最后我做了四件事。

installed latest version of nodejs which is i.e. 8.1.3
安装最新版本的nodejs，即8.1.3
installed npm which is 5.1.0 ( npm install npm@latest -g)
已安装的npm为5.1.0 (npm安装npm@latest -g)
installed typescript 2.4.1 ( npm install -g typescript)
已安装的打字稿2.4.1 (npm安装-g打字稿)
as suggested by @Uzair Sajid above. (tsc --init)
如上面的@Uzair Sajid所言。(tsc - init)

Now, I can see the TS version, and also compile the TS code.

现在，我可以看到TS版本，也可以编译TS代码。

I tried using the command line to set the target.

我尝试使用命令行设置目标。

tsc first.ts --target ES5

This created the first.js( compiled type script in javascript format).I manually moved this file to scripts folder.

这创造了第一个。js(用javascript格式编译的类型脚本)。我手动将这个文件移动到scripts文件夹。

Now when i ran the server using lite-server command. The browser could find the first.js file and ran the typescript code.

现在，当我使用lite-server命令运行服务器时。浏览器可以找到第一个。js文件并运行打字稿代码。
