Question

对于在我的package.json文件中为本地安装的模块设置的任何脚本，npm表示找不到该命令。

下面是我的package.json。我已经运行了“ npm install”，安装软件包没有任何问题。

{
  "name": "app",
  "private": true,
  "dependencies": {
    "@babel/core": "^7.8.6",
    "@babel/preset-env": "^7.8.6",
    "@babel/preset-react": "^7.8.3",
    "babel-loader": "^8.0.6",
    "bootstrap": "^4.4.1",
    "jquery": "^1.9.1",
    "react": "^16.13.0",
    "react-dom": "^16.13.0",
    "react-owl-carousel": "^2.3.1",
    "react-redux": "^7.2.0",
    "react-router-dom": "^5.1.2",
    "react-slick": "^0.25.2",
    "reactstrap": "^8.4.1",
    "redux": "^4.0.5",
    "redux-logger": "^3.0.6",
    "redux-thunk": "^2.3.0",
    "slick-carousel": "^1.8.1",
    "webpack-cli": "^3.3.11"
  },
  "scripts": {
    "postinstall": "webpack",
    "start": "webpack --watch --mode=development"
  },
  "engines": {
    "node": "10.13.0",
    "npm": "6.4.1"
  },
  "devDependencies": {
    "css-loader": "^3.4.2",
    "style-loader": "^1.1.3",
    "webpack": "^4.42.0"
  }
}

当我尝试从根文件运行npm start时，出现以下错误：

sh: webpack: command not found
npm ERR! file sh
npm ERR! code ELIFECYCLE
npm ERR! errno ENOENT
npm ERR! syscall spawn
npm ERR! app@ start: `webpack --watch --mode=development`
npm ERR! spawn ENOENT
npm ERR! 
npm ERR! Failed at the app@ start script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

我在多个项目中都有同样的问题。如果我在全球范围内安装，它将可以正常工作，但是据我对webpack的了解，这不是必须的，因此不建议使用：https://webpack.js.org/guides/installation/#global-installation。

有什么想法可能会带来麻烦吗？谢谢！

问题是我的应用所在的目录的目录名称中有一个/（例如a/b > app > node_modules）。 /被解释为:，npm不喜欢。

找不到本地安装的NPM模块命令
