节点找不到全局安装的npm模块

Question

node (18.7.0) cannot find globally installed npm (8.18.0) module.

My app.js includes:

let jp = require('jsonpath')

Command lines & outputs:

$ npm install -g jsonpath
…

$ npm -g list
/usr/local/lib
├── @aws-amplify/cli@9.2.1
├── jsonpath@1.1.1
└── npm@8.18.0

$ node app.js                  

node:internal/modules/cjs/loader:959
  throw err;
  ^

Error: Cannot find module 'jsonpath'

Node.js v18.7.0

Answer 1

Yes, this won't work! Because your app.js will use jsonpath in current project node_modules , not the one you installed globally. You have to install library in current project, just simply run:

npm install jsonpath

Then it will work properly!

Answer 2

Hi yes As a friend said open terminal in your path project and type

npm i jsonpath
