推送到 Heroku 时出现 Bower 错误：bower ENOTDIR ENOTDIR，不是目录 '/tmp/build_xxx/bower_components

Question

当我尝试在 Heroku 上推送 ember-cli 项目时遇到问题。 这是返回给我的日志。

我尝试使用 heroku-repo 清除缓存，但仍然是同样的问题。

如果我用 ember build 编译项目，就没有问题。只是消息：

bower invalid-meta  ember is missing "ignore" entry in bower.json

部署之前工作过。

今天遇到了同样的问题。这似乎是由最新的 bower 版本 1.6.2 引起的——强制版本为 1.5.3 解决了这里的问题。
