无法将tsc识别为内部或外部命令 [英] tsc is not recognized as internal or external command

问题描述

我从VSCode 0.10.6更新到0.10.8，并首次尝试使用Typescript.不幸的是，当我告诉VSCode构建时，出现错误:

I updated from VSCode 0.10.6 to 0.10.8, and tried using Typescript for the first time. Unfortunately I when I tell VSCode to build, I get the error:

tsc未被识别为内部或外部命令...

tsc is not a recognized as an internal or external command...

以下是相关详细信息:

• 我根据VS Code指令创建了一个新的"HelloWorld"项目 .这包括:
  • 我运行了npm init一个新的包.json
  • 我之所以运行npm i --save-dev typescript是因为我想要本地安装，而不是全局安装.
  • 我创建了launch.json来定义一个node.js项目.
  • 我创建了task.json文件，并为tsc指定了设置.
  • I created a fresh "HelloWorld" project according to VS Code instructions. This included:
    • I ran npm init for a new package.json
    • I ran npm i --save-dev typescript because I want a local install, rather than a global install.
    • I created a launch.json to define a node.js project.
    • I created the tasks.json file, with prescribed settings for tsc.

    我已经重新启动了VSCode(几次).我想念什么?还必须做些什么?

    I have restarted VSCode (several times). What am I missing? What more must be done?

    我尝试了@zlumer提供的解决方案.它成功使Typescript编译器运行，但随后导致成千上万的错误出现.为了解决这个问题，我还必须调整tsconfig.json以排除node_modules文件夹:

    I tried the solution offered by @zlumer. It succeeded in making the typescript compiler run, but then it caused thousands of errors to appear. To fix that, I also had to adjust my tsconfig.json to exclude the node_modules folder:

    "exclude": [
        "node_modules"
    ]
    

    推荐答案

    问题是，如果在本地安装tsc，则tsc不在您的PATH中.

    The problem is that tsc is not in your PATH if installed locally.

    您应该修改您的.vscode/tasks.json，以包含tsc的完整路径.

    You should modify your .vscode/tasks.json to include full path to tsc.

    要更改的行可能等于"command": "tsc".

    您应该将其更改为"command": "node"并将以下内容添加到您的参数中:"args": ["${workspaceRoot}\\node_modules\\typescript\\bin\\tsc"](在Windows上).

    You should change it to "command": "node" and add the following to your args: "args": ["${workspaceRoot}\\node_modules\\typescript\\bin\\tsc"] (on Windows).

    这将指示VSCode执行以下操作:

    This will instruct VSCode to:

    1. 运行NodeJS(应将其全局安装).
    2. 将本地Typescript安装作为运行脚本传递.

    (这几乎是tsc可执行文件的作用)

    (that's pretty much what tsc executable does)

    您确定不想全局安装Typescript吗?它应该使事情变得更容易，尤其是在您刚开始使用它的时候.

    Are you sure you don't want to install Typescript globally? It should make things easier, especially if you're just starting to use it.
