在跨平台的npm脚本中使用环境变量 [英] Using environment variables in npm scripts across platforms

问题描述

我正在构建package.json并使用"npm run"运行一些脚本，确切地说， https://docs.npmjs.com/misc/scripts .

I am building a package.json and use "npm run" to run some scripts, to be exactly, https://docs.npmjs.com/misc/scripts.

我的脚本需要扩展一些环境变量，我想使其跨平台兼容.例如，我的脚本会说

My script would need to expand some environment variables and I want to make it cross platform compatible. For example, my script would say

"scripts": {
  "build": "md %npm_package_version%\helloworld"
}

但是由于环境变量的扩展，它当前正在Windows上运行. Linux将使用md $npm_package_version\helloworld.

But it's currently running on Windows because the expansion of environment variables. Linux would use md $npm_package_version\helloworld.

npm是否带有转换环境变量扩展的机制，以便它可以跨平台工作?

Does npm comes with a mechanism to convert environment variables expansion so that it works across platforms?

推荐答案

要使其跨平台，请使用

To make it cross-platform, use cross-var:

"scripts": {
  "build": "cross-var md %npm_package_version%\helloworld"
}
