操作系统独立访问package.json中的变量 [英] OS independent access to variables in package.json

问题描述

要在npm脚本中访问变量，您可以在package.json中执行以下操作:

To access a variable in npm scripts you would do something like this in your package.json:

"scripts": {
    "preinstall": "echo ${npm_package_name}"
}

问题是只能在Unix下使用，而在Windows中则必须使用%npm_package_name%.

The problem is that works only in Unix, not Windows, where you have to use %npm_package_name%.

有没有办法独立于此操作系统?如果npm可以在调用命令之前进行这样的变量扩展，那就太好了.

Is there a way to do this OS independent? It will be good if npm could do such a variable expansion, before invoking the command.

推荐答案

要使其跨平台，请使用

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

"scripts": {
    "preinstall": "cross-var echo ${npm_package_name}"
}
