这是在我使用以下工具更新所有软件包后开始发生的：

npm-check-updates

因此，错误不会发生在我最初运行npm检查更新并更新包的机器上。但在其他地方都会发生

我想，如果我通过brew将node更新到最新版本，我应该解决这个问题，但我想了解为什么会失败，以及如何检测以防止将来发生这种情况

+++更新+++

所以，我决定跑步

brew install nvm

通过nvm安装了最新的节点版本

nvm install 7.4.0

---

但问题依然存在！在我无法复制问题的机器上，有节点7.4.0和npm 4.0.5。所以，我对发生的事一无所知

好的，我有npm收缩包装，这妨碍了npm安装正常运行

---

解决方案是删除npm shrinkwrap。

您使用代理吗？我没有使用代理，我尝试了wget和curl，效果很好
