为什么每次在名字和URL之间都会出现npm-收缩包装触发器？

Question

使用：

节点v4.6.2，npm 2.15.5，nvm 0.29.0，Homebrew 1.1.1-64-g17bad9a，macOS 10.12.1

步骤：

• 我更新package.json，
• 删除所有模块：rm -fr node_modules，
• 重新安装所有东西：nvm exec npm install，
• 并更新收缩包装：nvm exec npm shrinkwrap --dev。

结果：

每一次，每个模块的from字段都会在名称和URL之间发生变化，如npm-shrinkwrap.json diff的部分捕获所示：

diff --git a/npm-shrinkwrap.json b/npm-shrinkwrap.json
index e1f679a..476febe 100644
--- a/npm-shrinkwrap.json

我来自一个Ruby世界，我不明白这背后的逻辑。为什么每次运行npm时，都要在URL和名称之间进行更改？在我看来，这使得npm-shrinkwrap.json在版本控制上不可行。

如何使npm-shrinkwrap一致并且只使用URL或名称？
