终端中的npm错误和警告

Question

can anybody tells me what are those errors about and how to fix them? Everytime i try to install something in node with npm these errors show up in terminal enter image description here

Answer 1

The error you are facing is because you do not have package.json file. Npm installs the package in a node_modules/ subfolder, but warns you that there is no package.json file. If you want to manage localy installed npm packages you should create a package.json file. Start by creating an empty folder:

$ mkdir myapp
$ cd myapp

and then create a new package.json executing

$ npm init

Answer (or skip) all questions and at the end a brand new package.json will be created.

You can get more information from the Getting started articles in npm documentation: Working with package.json

Answer 2

ENOENT stands for basically "Error, No Entry". this means it was looking for the package.json file and it couldn't find it.The fields mentioned below are also not found because they are a part of the package.json file

so create a package.json file in the current current directory using

npm init

and add the required content in the required fields i would also recommend you to install the modules locally into the directory of the particular project using

npm install express --save 

Hope my answer helps, cheers
