1 环境

win7 win10

2 问题

我要执行的npm script如下: 
(脚本的内容不需要关注,需要关注的是它的写法。)

"scripts": {
    "test": "mocha --require ignore-styles --compilers js:babel-core/register --require             spec/helpers/browser.js --recursive spec/**/*_spec.*",
    "cover": "babel-node node_modules/.bin/babel-istanbul cover _mocha -- --require ignore-styles spec/helpers/browser.js --recursive spec/**/*_spec.*",
    "dev": "NODE_ENV=dev webpack --watch --colors --progress --debug --output-pathinfo --devtool eval-cheap-source-map",
    "dev-slow": "NODE_ENV=dev webpack --watch --colors --progress --debug --output-pathinfo --devtool inline-source-map",
    "dev-fast": "echo 'dev-fast in now replaced by dev'",
    "prod": "NODE_ENV=production node --max_old_space_size=4096 ./node_modules/webpack/bin/webpack.js -p --colors --progress",
    "build": "NODE_ENV=production webpack --colors --progress",
    "lint": "eslint --ignore-path=.eslintignore --ext .js,.jsx .",
    "lint-fix": "eslint --fix --ignore-path=.eslintignore --ext .js,.jsx .",
    "sync-backend": "babel-node --presets env src/syncBackend.js"
  },

运行脚本都报同样的错误:

'NODE_ENV' 不是内部或外部命令,也不是可运行的程序
或批处理文件。

  • 简单来说,就是windows不支持NODE_ENV=development的设置方式。
  • 经过一番搜索,我找到了解决方法:cross-env
  • 这个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,然后在windows上也能兼容运行。
  • 使用方法:

  • 安装cross-env:yarn add cross-env --dev
  • NODE_ENV=xxxxxxx前面添加cross-env就可以了。
  •  "scripts": {
        "test": "mocha --require ignore-styles --compilers js:babel-core/register --require spec/helpers/browser.js --recursive spec/**/*_spec.*",
        "cover": "babel-node node_modules/.bin/babel-istanbul cover _mocha -- --require ignore-styles spec/helpers/browser.js --recursive spec/**/*_spec.*",
        "dev": "cross-env NODE_ENV=dev webpack --watch --colors --progress --debug --output-pathinfo --devtool eval-cheap-source-map",
        "dev-slow": "cross-env NODE_ENV=dev webpack --watch --colors --progress --debug --output-pathinfo --devtool inline-source-map",
        "dev-fast": "cross-env echo 'dev-fast in now replaced by dev'",
        "prod": "cross-env NODE_ENV=production node --max_old_space_size=4096 ./node_modules/webpack/bin/webpack.js -p --colors --progress",
        "build": "cross-env NODE_ENV=production webpack --colors --progress",
        "lint": "eslint --ignore-path=.eslintignore --ext .js,.jsx .",
        "lint-fix": "eslint --fix --ignore-path=.eslintignore --ext .js,.jsx .",
        "sync-backend": "babel-node --presets env src/syncBackend.js"
      },

   然后执行yarn dev即可运行,修改了文件可以直接预编译。开发效率也加快了
