本篇主要解决如下问题：
Error: Invalid Plugin! <plugin name> needs a valid package.json
pkg is not defined
终端切换至自定义插件文件夹的位置：执行如下命令
1. npm init
This utility will walk you through creating a package.json file.
It only covers the most common items, and tries to guess sensible defaults.
See `npm help json` for definitive documentation on these fields
and exactly what they do.
Use `npm install --save` afterwards to install a package and
save it as a dependency in the package.json file.
Press ^C at any time to quit.
name: (<plugin name>)
2.输入你的自定义插件名称，不能含大写字母。
3.接下来要填写的信息可依次回车。
version: (1.0.0)
description:
entry point: (index.js)
test command:
git repository:
keywords:
author:
license: (ISC)
About to write to /Users/..<path> ./pluginName/package.json:
{
"name": "<plugin name>",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"author": "",
"license": "ISC"
}
Is this ok? (yes)
4.敲入y 即可。
备注，也可以手动创建package.json文件，按照如上(最外层{})格式。未验证。
