如何在 npm 中本地安装和运行 Typescript？

Question

我想安装和运行 Typescript（即没有全局依赖项）。

这是我的 package.json 文件：

 {
  "name": "foo",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "tsc": "tsc"
  },
  "devDependencies": {
    "typescript": "^1.8.10"
  },
  "author": "",
  "license": "ISC"
}

然后我运行：

 npm install
npm run tsc

但是，当我运行第二个命令时，我得到了太多错误，它无法全部显示。大部分是这样的：

 ../foo/node_modules/typescript/lib/lib.d.ts(5015,5): error TS2300: Duplicate identifier 'webkitTransformOrigin'.
../foo/node_modules/typescript/lib/lib.d.ts(5016,5): error TS2300: Duplicate identifier 'webkitTransformStyle'.
../foo/node_modules/typescript/lib/lib.d.ts(5017,5): error TS2300: Duplicate identifier 'webkitTransition'.
../foo/node_modules/typescript/lib/lib.d.ts(5018,5): error TS2300: Duplicate identifier 'webkitTransitionDelay'.
../foo/node_modules/typescript/lib/lib.d.ts(5019,5): error TS2300: Duplicate identifier 'webkitTransitionDuration'.
../foo/node_modules/typescript/lib/lib.d.ts(5020,5): error TS2300: Duplicate identifier 'webkitTransitionProperty'.

在 npm-debug.log 我得到：

23 error Or if that isn't available, you can get their info via:
23 error     npm owner ls foo
23 error There is likely additional logging output above.
24 verbose exit [ 1, true ]

请注意，删除软件包然后全局安装 typescript 可以解决问题。但是，如果我随后使用 npm install 再次安装本地软件包，它会重新引入问题。

要在项目中本地安装 TypeScript 作为开发依赖项，您可以使用 --save-dev 键

npm install --save-dev typescript

它还将打字稿写入您的 package.json

您还需要有一个 tsconfig.json 文件。例如

{
  "compilerOptions": {
    "target": "ES5",
    "module": "system",
    "moduleResolution": "node",
    "sourceMap": true,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "removeComments": false,
    "noImplicitAny": false
  },
  "exclude": [
    "node_modules",
    ".npm"
  ]
}

有关 tsconfig 的更多信息，您可以在此处查看 http://www.typescriptlang.org/docs/handbook/tsconfig-json.html

我花了一段时间才弄清楚这个问题的解决方案——它在最初的问题中。您需要有一个 script 调用 tsc 在您的 package.json 文件中，以便您可以运行：

 npm run tsc

在传递选项之前包括 -- （或仅将它们包含在脚本中）：

 npm run tsc -- -v

这是一个示例 package.json ：

 {
  "name": "foo",
  "scripts": {
    "tsc": "tsc"
  },
  "dependencies": {
    "typescript": "^1.8.10"
  }
}
