我已经部署了应用程序，部署成功了。但是我发现package.json中缺少express，所以应用程序无法运行。我已经在包中添加了express依赖列表，再次部署之后我看到express仍然缺少所以我添加了带依赖关系的bower.json文件来在package.json postinstall: bower install列表中运行scripts:{}命令，这样express将通过bower安装在服务器上。但我现在面临的问题是：

即使从package.json中删除postinstall命令并完全删除了bower.json文件，我在部署应用程序时也会在控制台上遇到同样的问题。

除非您的服务器上全局安装了凉亭，否则可能是这样：
"scripts": {
"postinstall": "./node_modules/bower/bin/bower install"
}
