node.js - package.json中的tilde（?）和caret（^）有什么区别？(What's the difference between tilde(~) and caret(^) in package.json?)

Question

After I upgraded to latest stable node and npm , I tried npm install moment --save .

(升级到最新的稳定node和npm ，我尝试了npm install moment --save 。)

It saves the entry in the package.json with the caret ^ prefix.

(它将条目以尖号^保存在package.json 。)

Previously, it was a tilde ~ prefix.

(以前，它是一个波浪号~前缀。)
