sh: 1: node_modules/webpack？

删除 node_modules 目录之后重新 yarn

先看一下你npm的版本，npm 5.0以上的版本执行npm install的时候默认不会执行devDependence下面的包

重新yarn 报错

好像解决了 apt-get install libpng-dev 就行了 谢谢

安装的坑我终于采完了

.version(); 不能加 加上 npm run watch-poll 会报错啊

配置

• windows 安装 （使用cmd）

  yarn install --no-bin-links

• 配置如下

  {
  "private": true,
  "scripts": {
  "dev": "npm run development",
  "development": "cross-env node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
  "watch": "npm run development -- --watch",
  "watch-poll": "npm run watch -- --watch-poll",
  "hot": "cross-env 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": "cross-env node_modules/webpack/bin/webpack.js --no-progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js"
  },
  "devDependencies": {
  "axios": "^0.18",
  "bootstrap": "^4.0.0",
  "cross-env": "^5.2.0",
  "jquery": "^3.2",
  "laravel-mix": "^4.0.7",
  "lodash": "^4.17.5",
  "popper.js": "^1.12",
  "resolve-url-loader": "^2.3.1",
  "sass": "^1.15.2",
  "sass-loader": "^7.1.0",
  "vue": "^2.5.17"
  }
  }

• 安装 cross-env

  cnpm install cross-env --save-dev
  cnpm install

  npm run watch-poll
