节点找不到IP模块

Question

I am trying to use the IP module in a Node program. However, whenever I try to add it in using const ip = require("ip") , I get the following error:

internal/modules/cjs/loader.js:584
    throw err;
    ^

Error: Cannot find module 'ip'
    at Function.Module._resolveFilename (internal/modules/cjs/loader.js:582:15)
    at Function.Module._load (internal/modules/cjs/loader.js:508:25)

    at tryModuleLoad (internal/modules/cjs/loader.js:539:12)
    at Function.Module._load (internal/modules/cjs/loader.js:531:3)

Why is this happening? I have installed and reinstalled the latest version of IP several times globally on my computer, and all other Node modules work fine.

Answer 1

Try this:

  npm uninstall ip -g --save

Then:

  npm install ip -g --save

I don't know if --save is required anymore but I have had the issue that without this flag the module could not be found. Hope this helps.
