如何将 Typescript 升级到最新版本？

How to upgrade Typescript to the latest version?

提问by Cesco

I have a MacBook Pro with OS X 10.8.2 Some time ago I installed Typescript and today I'd like to upgrade that installation to the latest version available (so far, v0.8.3). I wrote this command from the terminal:

我有一台装有 OS X 10.8.2 的 MacBook Pro 前段时间我安装了 Typescript，今天我想将该安装升级到可用的最新版本（到目前为止，v0.8.3）。我从终端写了这个命令：

sudo npm install -g typescript

But this is what I got on the display:

但这是我在显示器上看到的：

npm http GET https://registry.npmjs.org/typescript
npm http 304 https://registry.npmjs.org/typescript
/usr/local/bin/tsc -> /usr/local/lib/node_modules/typescript/bin/tsc
[email protected] /usr/local/lib/node_modules/typescript

Does this means that I still have version 0.8.0 installed on my computer? I tried to see if the tsc command has a -vor a -versionparameter but I haven't found it, so I still uncertain if I have upgraded Typescript to the latest release or if I'm still stuck with an older version.

这是否意味着我的计算机上仍然安装了 0.8.0 版？我试图查看 tsc 命令是否有一个-v或一个-version参数，但我没有找到它，所以我仍然不确定我是否已将 Typescript 升级到最新版本，或者我是否仍然坚持使用旧版本。

I just realised that I was using an old version of npm. I have upgraded npm to the latest version, then re-installed typescript and now I have the latest version of typescript installed on my computer.

我刚刚意识到我使用的是旧版本的 npm。我已将 npm 升级到最新版本，然后重新安装了 typescript，现在我的计算机上安装了最新版本的 typescript。

Since selected correct answer didn't help me I figured I'd share how I resolved the issue.

由于选择的正确答案对我没有帮助，我想我会分享我是如何解决这个问题的。

I had to remove C:\Program Files (x86)\Microsoft SDKs\TypeScript\1.0\from my PATH.

我不得不C:\Program Files (x86)\Microsoft SDKs\TypeScript\1.0\从我的路径中删除。

After that I could run this command and see the version I was expecting:

之后，我可以运行此命令并查看我期望的版本：

C:\>tsc --version
message TS6029: Version 1.5.3

For those still struggling with that - try running WHERE tscin Command Prompt or Node.js Command Prompt and you'll get all the locations it is installed. Remove the excessive location from PATH env var.

对于那些仍在为此苦苦挣扎的人 - 尝试WHERE tsc在命令提示符或 Node.js 命令提示符中运行，您将获得它安装的所有位置。从 PATH env var 中删除过多的位置。

Even when i installed latest typescript, still i was getting version as 1.0.3 when doing tsc -v

即使我安装了最新的打字稿，在执行 tsc -v 时我仍然获得 1.0.3 版本

The corrected answer didn't help me , but followed @BenR approach, removed this PATH C:\Program Files (x86)\Microsoft SDKs\TypeScript\1.0\ from System Variables

更正的答案对我没有帮助，但遵循@BenR 方法，从系统变量中删除了此 PATH C:\Program Files (x86)\Microsoft SDKs\TypeScript\1.0\

and then opened new windows command prompt and then typed

然后打开新的 Windows 命令提示符，然后键入

tsc -v
Version 2.3.3

So now i was able to compile the typescript files using tsc file.ts

所以现在我能够使用编译打字稿文件 tsc file.ts

Hope this helps someone.

希望这可以帮助某人。

Open a command line tool cmd.exe/Git Bashand execute:

打开命令行工具cmd.exe/Git Bash并执行：

 npm install -g typescript@latest

The command will do the following:

该命令将执行以下操作：

Check if Typescript is installed and ..

检查是否安装了 Typescript 并且..

1. if installed already, updateit to the latest version
2. if not installed, installthe latest version

1. 如果已经安装，请更新到最新版本
2. 如果没有安装，请安装最新版本

It has been reported that the following command will not work reliably when you already have typescript installed:

据报道，当您已经安装了 typescript 时，以下命令将无法可靠运行：

npm update -g typescript@latest

Test the versionusing

测试版本使用

tsc -v  // prints out the locally installed typescript version

Furthermore you can check, which is the latest available version for typescript in the npm registry:

此外，您可以检查npm 注册表中打字稿的最新可用版本：

npm view typescript version  // prints the latest available version in the npm registry

I had the same problem on Linux, possibly related to using node version manager.

我在 Linux 上遇到了同样的问题，可能与使用节点版本管理器有关。

I fixed it by finding where tsc was and then manually going in and deleting those folders

我通过找到 tsc 的位置然后手动进入并删除这些文件夹来修复它

$ which tsc
/home/vagrant/.nvm/versions/node/v6.9.5/bin/tsc

$ cd /home/vagrant/.nvm/versions/node/v6.9.5/bin/
$ ll
...
lrwxrwxrwx 1 vagrant vagrant       38 Nov 30 10:32 tsc -> ../lib/node_modules/typescript/bin/tsc*
lrwxrwxrwx 1 vagrant vagrant       43 Nov 30 10:32 tsserver -> ../lib/node_modules/typescript/bin/tsserver*
...

$ rm -rf ../lib/node_modules/typescript/ tsc tsserver

1. I had Visual Studio installed on my Windows OS computer, which added its own version of TypeScript installation into the System Path
2. Uninstalled 'TypeScript for Visual Studio' from Programs and Features
3. Installed latest typescript. From command prompt 'npm install -g typescript@latest'
4. Issue solved!

1. 我在 Windows 操作系统计算机上安装了 Visual Studio，它将自己的 TypeScript 安装版本添加到系统路径中
2. 从程序和功能中卸载“TypeScript for Visual Studio”
3. 安装了最新的打字稿。从命令提示符'npm install -g typescript@latest'
4. 问题解决了！

I know this is an old Question, but I faced a similar issue and none of the answers here solved it, posting my answer for anyone else in the same boat.

我知道这是一个老问题，但我遇到了类似的问题，这里的答案都没有解决它，将我的答案发布给同一条船上的其他人。

I just faced this issue on the windows 8 machine with blocked admin access where I was unable to uninstall global typescript, modify PATHetc.

我刚刚在 Windows 8 机器上遇到了这个问题，管理员访问被阻止，我无法卸载全局打字稿，修改PATH等。

Here's how to launch typescript projects in this case:

以下是在这种情况下启动打字稿项目的方法：

1. install local typescript version for project npm install typescript@latest( avoid -gparam)

2. add build scripts to package.jsone.g.

   scripts: { "clean": "rimraf coverage build tmp", "build": "tsc -p tsconfig.release.json", "build:watch": "tsc -w -p tsconfig.release.json", "lint": "tslint -t stylish --project \"tsconfig.json\"", "test": "jest --coverage", "test:watch": "jest --watch" }

3. run typescript compiler with the local version of typescript via npm run build:watchwhich will launch tsc -w -p tsconfig.release.jsonusing project's local tscfrom node_modules

1. 为项目安装本地打字稿版本npm install typescript@latest（避免-g参数）

2. 将构建脚本添加到package.json例如

   scripts: { "clean": "rimraf coverage build tmp", "build": "tsc -p tsconfig.release.json", "build:watch": "tsc -w -p tsconfig.release.json", "lint": "tslint -t stylish --project \"tsconfig.json\"", "test": "jest --coverage", "test:watch": "jest --watch" }

3. 运行带有打字稿的本地版本打字稿编译通过npm run build:watch，将推出tsc -w -p tsconfig.release.json使用项目的本地tsc从node_modules

I encountered the same issue and none of the popular answers resolved the problem for me. I'm on Windows 10 with Visual Studio 2017.

我遇到了同样的问题，但没有一个流行的答案为我解决了这个问题。我在 Windows 10 上使用 Visual Studio 2017。

I tried using where tscfrom the console to determine where the path to tscwas resolving. The first entry was similar to: C:\Program Files (x86)\Microsoft SDKs\TypeScript\x.xx. So I checked the PATHvariable (both System and User) and that path was nowhere to be found.

我尝试where tsc从控制台使用来确定tsc解析路径的位置。第一个条目类似于：C:\Program Files (x86)\Microsoft SDKs\TypeScript\x.xx。所以我检查了PATH变量（系统和用户）并且找不到那个路径。

I finally stumbled across this comment on GitHub: https://github.com/Microsoft/TypeScript/issues/4971#issuecomment-144184935

我终于在 GitHub 上偶然发现了这条评论：https: //github.com/Microsoft/TypeScript/issues/4971#issuecomment-144184935

Which pointed me in the right direction. I use Console2and my default console tab spawns a Visual Studio-enhanced console via this .batfile: C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\Tools\VsDevCmd.bat

这为我指明了正确的方向。我使用Console2并且我的默认控制台选项卡通过此.bat文件生成了一个 Visual Studio 增强的控制台： C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\Tools\VsDevCmd.bat

That .batfile doesn't contain anything TypeScript-specific, but it does run all the .batfiles found in C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\Tools\vsdevcmd\ext. And one of thosefiles is conspicuously named typescript.bat. I simply renamed that filed to some other extension, then re-opened a console and now everything is great.

这.bat文件不包含打字稿特定的东西，但它并运行所有.bat找到的文件C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\Tools\vsdevcmd\ext。和一个这些文件被命名为明显typescript.bat。我只是将其重命名为其他扩展名，然后重新打开控制台，现在一切都很好。

Not sure if this will bork up anything in Visual Studio, but I don't use it for TypeScript. And I suspect a future Visual Studio update may put that file back in place. But it works for now.

不确定这是否会破坏 Visual Studio 中的任何内容，但我不将它用于 TypeScript。我怀疑未来的 Visual Studio 更新可能会将该文件放回原处。但它现在有效。
