'Object.keys called on non-object' 将 Bower 从 1.3.12 版升级到 1.4.1 版时出错

Question

在我运行bower install之后，我得到一个警告：

┌───────────────────────────────────────────┐
│ Update available: 1.4.1 (current: 1.3.12) │
│ Run npm update -g bower to update.        │
└───────────────────────────────────────────┘

如果我按照说明和运行 update 命令进行操作，我会得到一个 'Object.keys called on non-object' 错误列表

> npm update  -g bower                                                                                                                                                 ✭ ✱
