今天在安装js依赖包时,根目录的package.json:

{
"private": true,
"scripts": {
"dev": "$npm_package_scripts_development",
"development": "cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
"watch": "cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --watch --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
"watch-poll": "cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --watch --watch-poll --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
"hot": "cross-env NODE_ENV=development node_modules/webpack-dev-server/bin/webpack-dev-server.js --inline --hot --config=node_modules/laravel-mix/setup/webpack.config.js",
"prod": "$npm_package_scripts_production",
"production": "cross-env NODE_ENV=production node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js"
},
"devDependencies": {
"axios": "^0.15.3",
"bootstrap": "^3.3.7",
"cross-env": "^3.2.3",
"jquery": "^3.1.1",
"laravel-mix": "0.*",
"lodash": "^4.17.4",
"swiper": "^3.4.2"
},
"dependencies": {
"cross-env": "^3.2.4"
}
}

在执行nmp install时出现以下错误

Failed at the @ watch script 'cross-env NODE_ENV=development 使用cross-env解决跨平台设置NODE_ENV的问题-LMLPHP

谷歌了下这个cross-env迷你的包能够提供一个设置环境变量的scripts,让你能够以unix方式设置环境变量,

安装使用方法:

  • 安装cross-env: npm install cross-env --save-dev

  • NODE_ENV=xxxxxxx前面添加cross-env就可以了(本例中已经加了cross-env)。
    在此执行npm install,ok 正常
