NPM更新搞砸了我的package.json

Question

我有一个package.json文件，我在我的入门Web项目基础上使用了几个月。今天我将NPM更新到最新版本并在2天前工作时遇到这些错误：

Darwin 15.4.0
npm ERR! argv "node" "/usr/local/bin/npm" "install"
npm ERR! node v0.12.7
npm ERR! npm  v3.8.6
npm ERR! path /Users/PackyTagliaferro/.npm/_locks/staging-5068d5ea0bd1bbae.lock
npm ERR! code EACCES
npm ERR! errno -13

npm ERR! Error: EACCES, open '/Users/PackyTagliaferro/.npm/_locks/staging-5068d5ea0bd1bbae.lock'

npm ERR!   errno: -13,

npm ERR!   path: '/Users/PackyTagliaferro/.npm/_locks/staging-5068d5ea0bd1bbae.lock' }

npm ERR! Please try running this command again as root/Administrator.

非常害怕它搞砸了我的所有项目，如果我更新了Node.js或NPM我的项目将会破坏，现在更加害怕。
