【问题描述】：

我有一个使用 Mean.IO 编写并部署到 Heroku (Buildpack https://github.com/mbuchetics/heroku-buildpack-nodejs-grunt) 的应用程序。

在我今天早上的最新部署之前一直很好，并且无缘无故地坏了。鲍尔似乎运行良好

Done, without errors.

我看到了这条线

Error: ENOENT, open '.bower-cache/fe2fe255e91d251051d543998aa8327a-1.11.2.lock'

但我不确定这意味着 heroku 明智。有什么想法吗？

【解决方案1】：

尝试运行 bower update 它将安装缺少的 jQuery 依赖项

**Update NPM, Bower or Grunt**

Sometimes you may find there is a weird error during install 
like npm’s Error: ENOENT. Usually updating those tools to 
the latest version solves the issue.

Updating NPM:
$ npm update -g npm

Updating Grunt:
$ npm update -g grunt-cli

Updating Bower:
$ npm update -g bower
