在 Windows 10 中设置环境变量 package.json [英] Setting environment variables package.json in Windows 10

问题描述

UPDATE:正如问题中所解释的，这不是重复的，因为我已经尝试在环境变量之前添加 set 关键字，并且没有解决问题.

UPDATE: As it is explained in the question, this is not a duplicate because I have already tried adding the set keyword before the environment variable and that did not solve the problem.

我正在学习节点并从书中输入示例.第一个例子展示了http"模块如何工作以及如何创建一个服务器来监听请求.在某些时候，本书要求将以下行添加到 package.json 文件的脚本部分:

I am in the process of learning node and typing examples from a book. The first examples deal with showing how the "http" module works and how to create a server to listen to requests. At some point the book asks to add the following line to the scripts section of the package.json file:

"server": "SERVERPORT=3002 节点 ./fiboserver"

"server": "SERVERPORT=3002 node ./fiboserver"

当我尝试使用 npm run server 运行示例时，我收到以下错误消息:

When I try to run the example with npm run server I get the following error message:

'SERVERPORT' 未被识别为内部或外部命令

'SERVERPORT' is not recognized as an internal or external command

网上一直没找到答案，顶多发现可以试试:

I haven't been able to find any answer on the internet, at most I found that I could try:

"server": "设置 SERVERPORT=3002 节点 ./fiboserver"

"server": "set SERVERPORT=3002 node ./fiboserver"

但这也无济于事，唯一的区别是我再次收到命令提示符而不是错误消息，因此显然服务器永远不会运行.

But that doesn't help either, the only difference is that instead of the error message I get the command prompt again so apparently the server is never run.

我相信作者使用的是 Linux 机器，我使用的是 Windows 10 笔记本电脑.

I believe the author used a Linux machine, I am using a Windows 10 laptop.

我非常致力于学习 Node，我的工作是在 Windows 环境中进行的.我相信在 package.json 上设置环境变量很重要，所以我真的可以使用一些帮助来解决这个问题.

I am really committed to learn Node and my line of work is on Windows environments. I believe that setting environment variables on package.json is important so I could really use some help in figuring this out.

谢谢.

推荐答案

在 Windows 上，您必须将设置变量的命令与使用 && 运算符运行服务器的命令分开.话虽如此，你必须做这样的事情:

On Windows you have to separate the command of setting a variable from the one which runs the server with the && operator. That being said, you have to do something like this:

"server": "set SERVERPORT=3002 && node ./fiboserver"
