How do I install TypeScript?
提问by David Thielen
I have version 0.9.1.1. So I ran the following:
我有 0.9.1.1 版本。所以我运行了以下内容：
C:\test>npm install -g typescript
npm http GET https://registry.npmjs.org/typescript
npm http 200 https://registry.npmjs.org/typescript
npm http GET https://registry.npmjs.org/typescript/-/typescript-1.0.0.tgz
npm http 200 https://registry.npmjs.org/typescript/-/typescript-1.0.0.tgz
C:\Users\david\AppData\Roaming\npm\tsc -> C:\Users\david\AppData\Roaming\npm\nod
e_modules\typescript\bin\tsc
[email protected] C:\Users\david\AppData\Roaming\npm\node_modules\typescript
But when I run tsc I get:
但是当我运行 tsc 时，我得到：
C:\test>tsc
Version 0.9.1.1
Syntax: tsc [options] [file ..]
What else do I need to do to install the latest version?
我还需要做什么来安装最新版本？
Update:
更新：
C:\test>where tsc
C:\Program Files (x86)\Microsoft SDKs\TypeScript\tsc.exe
C:\Program Files (x86)\Microsoft SDKs\TypeScript\tsc.js
C:\Users\david\AppData\Roaming\npm\tsc
C:\Users\david\AppData\Roaming\npm\tsc.cmd
tsc.exe is 0.9.1.1 and tsc.cmd is 1.0.0.0
tsc.exe 是 0.9.1.1 和 tsc.cmd 是 1.0.0.0
I then removed the VisualStudio 0.9.1.1 AddIn and it's now all good - just tsc.cmd and that's 1.0.0.0
然后我删除了 VisualStudio 0.9.1.1 AddIn，现在一切都很好 - 只是 tsc.cmd 就是 1.0.0.0
Thank you all!
谢谢你们！

It is because you probably (almost definitely) have TypeScript plugin for visual studio installed. You can uninstall that from Control Panel. Then the typescript you installed from npmwill be the default one on the command line.
这是因为您可能（几乎肯定）安装了 Visual Studio 的 TypeScript 插件。您可以从控制面板卸载它。然后，您从npm安装的打字稿将成为命令行上的默认打字稿。
Alternatively you can get the latest TypeScript from Visual Studio 2012 plugin from here : http://www.typescriptlang.org/#Download(For VS 2013 it is bundled as a part of VS 2013 update 2 RC)
或者，您可以从这里获取来自 Visual Studio 2012 插件的最新 TypeScript：http: //www.typescriptlang.org/#Download（对于 VS 2013，它作为 VS 2013 update 2 RC 的一部分捆绑在一起）

Removing C:\Program Files (x86)\Microsoft SDKs\TypeScript\from PATHenvironment variable did the job for me.
C:\Program Files (x86)\Microsoft SDKs\TypeScript\从PATH环境变量中删除为我完成了这项工作。

For me, I just change the "Path" environment parameter from "C:\Program Files (x86)\Microsoft SDKs\TypeScript\1.0"to "C:\Program Files (x86)\Microsoft SDKs\TypeScript\1.5", then it's all ok.
对我来说，我只是将“Path”环境参数从"C:\Program Files (x86)\Microsoft SDKs\TypeScript\1.0"更改为"C:\Program Files (x86)\Microsoft SDKs\TypeScript\1.5"，然后就可以了。
