我正在尝试修改npm模块，我想将修改后的模块包含为本地依赖项。
在托管上部署此应用程序时，我面临一个奇怪的webpack未找到问题。我设法通过全局删除webpack来重现本地计算机中的问题。
我的package.json：
1）我尝试在package.json依赖项中包含本地模块：
{
"name": "parse-server-example",
"version": "1.4.0",
"description": "An example Parse API server using the parse-server module",
"main": "index.js",
"repository": {
"type": "git",
"url": "https://github.com/ParsePlatform/parse-server-example"
},
"license": "MIT",
"dependencies": {
"webpack": "2.3.3",
"express": "~4.11.x",
"kerberos": "~0.0.x",
"parse": "~1.8.0",
"parse-dashboard-simple": "./parse-dashboard-simple",
"parse-server": "*"
},
"scripts": {
"start": "node index.js"
},
"engines": {
"node": "7.6.0"
}
}
请注意我有一个名为“./parse-dashboard-simple”的本地模块。
我的本地模块的package.json：

如果我在此项目的根级别运行“ npm install ”，我将收到此错误：
npm WARN prepublish-on-install As of npm@5, `prepublish` scripts will run only for `npm publish`.
npm WARN prepublish-on-install (In npm@4 and previous versions, it also runs for `npm install`.)
npm WARN prepublish-on-install See the deprecation note in `npm help scripts` for more information.

所以我的理解是在预发布脚本中需要webpack但是找不到它。但是我故意在根项目或本地模块中添加了webpack作为依赖项（在开发和生产依赖中只是为了安全），为什么还没有找到webpack？
