在项目目录中安装 npm 模块时出现警告，但在全局安装时不会出现警告

Question

I have observed this issue when installing both newsapi and RequireJS. The path to my project directory is as follow: Users\\username\\project

In my project directory, when I run npm install newsapi --save (installation instructions per the newsapi site or npm install requirejs (installation instructions per the RequireJS site , I get the following identical warnings:

npm WARN saveError ENOENT: no such file or directory, open 'C:\Users\username\project\package.json'
npm WARN enoent ENOENT: no such file or directory, open 'C:\Users\username\project\package.json'
npm WARN project No description
npm WARN project No repository field.
npm WARN project No README data
npm WARN project No license field.

It may be worth noting the project\\node_modules\\newsapi and project\\node_modules\\requirejs are still created and they seems to be populated as they should.

I noticed that when I install the modules globally (by running npm install -g newsapi --save or npm install -g requirejs ) the installation succeeds without displaying any warnings. Why is this the case? What is happening in my project folder that might be causing this issue?

npm install fhqhwhgads will try to update the local project package.json but npm install -g fhqwhgads will install globally and so there's no package.json to update. So that's why you're note getting an warning with global installation.

If you want to create a package.json so that your dependencies can be tracked and replicated by others (or if you want to publish your code as a package), you can use npm init .
