Laravel5.5执行 npm run dev时报错，提示cross-env找不到（not found）的解决办法

Laravel 5.4 Mix & Laravel5.5执行 npm run dev时报错，提示cross-env找不到（not found）的解决办法

•  

  首先进入package.json文件，
  将scripts下的所有cross-env删除掉，（devDependencies下的不能删除）
  处理结果代码如下：

  {

  "private": true,

  "scripts": {

  "dev": "npm run development",

  "development": "NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",

  "watch": "NODE_ENV=development node_modules/webpack/bin/webpack.js --watch --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",

  "watch-poll": "npm run watch -- --watch-poll",

  "hot": "NODE_ENV=development node_modules/webpack-dev-server/bin/webpack-dev-server.js --inline --hot --config=node_modules/laravel-mix/setup/webpack.config.js",

  "prod": "npm run production",

  "production": "NODE_ENV=production node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js"

  },

  "devDependencies": {

  "axios": "^0.16.2",

  "bootstrap-sass": "^3.3.7",

  "cross-env": "^5.0.1",

  "jquery": "^3.1.1",

  "laravel-mix": "^1.0",

  "lodash": "^4.17.4",

  "vue": "^2.1.10"

  }

  }

   

  然后执行： npm install –no-bin-links

  如果这个过程有报错，需要再次执行：npm install –no-bin-links

  其次执行：yarn install –no-bin-links

  最后执行编译命令：npm run dev 或者 npm run watch-poll

  好了，完美解决此问题！
