NodeJS 如何在npm中本地安装和运行Typescript?

我想安装并运行Typescript(即,没有全局依赖性)。
下面是我的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

然而,当我运行第二个命令时,我得到了太多的错误,它不能显示所有的错误。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中,我得到:

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

我花了一段时间才想出这个问题的解决方案-它在原始问题中。你需要在package.json文件中有一个调用tscscript,这样你就可以运行:

npm run tsc

在传入选项之前包含--(或者只在脚本中包含它们):

npm run tsc -- -v

下面是一个package.json的例子:

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

从npm 5.2.0开始,一旦你通过本地安装了

npm i typescript --save-dev

.你不再需要package.jsonscripts部分中的条目--你现在可以用npx运行编译器:

npx tsc

现在,您不必在每次使用不同参数进行编译时都更新package.json文件。

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

npm install --save-dev typescript

它还将打印脚本写入package.json
您还需要一个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,请参见此处http://www.typescriptlang.org/docs/handbook/tsconfig-json.html

您需要告诉npm“tsc”作为本地项目包存在(通过package.json中的“scripts”属性),然后通过npm run tsc运行它。要做到这一点(至少在Mac上),我必须在包中添加实际编译器的路径,如下所示

{
  "name": "foo"
  "scripts": {
    "tsc": "./node_modules/typescript/bin/tsc"
  },
  "dependencies": {
    "typescript": "^2.3.3",
    "typings": "^2.1.1"
  }
}

之后,您可以运行任何TypeScript命令,如npm run tsc -- --init(参数在第一个--之后)。

您现在可以使用ts-node,这使您的生活变得简单,

npm install -D ts-node
npm install -D typescript

ts-node script.ts

tsc需要配置文件或.ts(x)文件来编译。
要解决这两个问题,请创建一个名为tsconfig.json的文件,其中包含以下内容:

{
    "compilerOptions": {
        "outFile": "../../built/local/tsc.js"
    },
    "exclude": [
        "node_modules"
    ]
}

另外,用这个修改你的npm运行

tsc --config /path/to/a/tsconfig.json

如果你使用typings,请注意:

rm -r typings
typings install

如果你正在使用angular 2教程,请使用这个:

rm -r typings
npm run postinstall
npm start

如果postinstall命令不起作用,请尝试像这样全局安装类型:

npm install -g typings

您也可以尝试以下操作,而不是postinstall:

typings install

你应该有这个问题固定!

也许这可以帮助:“npx ts-node --esm file.ts”Nodemon命令:nodemon --exec npx ts-node --esm test.ts
