无法运行npm install [英] Can't run npm install

问题描述

在此处它说要运行 npm install ，但是运行 sudo npm install 时出现此错误.

In here it says to run npm install, but I get this error when I run sudo npm install.

sudo npm install
npm WARN enoent ENOENT: no such file or directory, open '/var/www/html/mg/package.json'
npm WARN mg No description
npm WARN mg No repository field.
npm WARN mg No README data

没有sudo:

npm install

npm WARN mg No description
npm WARN mg No repository field.
npm WARN mg No README data
npm WARN mg No license field.

推荐答案

您需要具有一个 package.json 文件，该文件才能正常工作.

You need to have a package.json file for that to work.

您可以通过运行以下命令来创建它:

You can create it by running:
