将package.json里面
"scripts": {
"dev": "node ./tools/gulpfile.js&&node ./tools/webpack.config.js",
"pub": "node ./tools/gulpfile.js&&export NODE_ENV=PROD&&node ./tools/webpack.config.js"
}

改为：

"scripts": {
"dev": "node ./tools/gulpfile.js&&node ./tools/webpack.config.js",
"pub": "node ./tools/gulpfile.js&&set NODE_ENV=PROD&&node ./tools/webpack.config.js"
}

打包成功了
