npm错误！404未找到：1.9。1@latest

我将一个项目克隆到我的本地回购：

$  npm i 
npm WARN cropper@3.1.4 requires a peer of jquery@>= 1.9.1 but none is installed. You must install peer dependencies yourself.
npm WARN The package iview is included as both a dev and production dependency.
npm WARN The package vuex is included as both a dev and production dependency.

但是当我手动安装jquery@>=1.9.1依赖项时，我得到了找不到的错误：

$ npm install jquery@>= 1.9.1 --save-dev
npm ERR! code E404
npm ERR! 404 Not Found: 1.9.1@latest

npm ERR! A complete log of this run can be found in:
npm ERR!     /Users/luowensheng/.npm/_logs/2018-02-12T07_13_29_793Z-debug.log

这条线是什么

npm警告cropper@3.1.4需要jquery@>=1.9.1的对等机，但未安装任何对等机。您必须自己安装对等依赖项

意思是你需要一个大于1.9.1的jquery版本

照办

npm安装jquery@^1.9.1或npm安装jquery@latest如果您想要最新的jquery版本，即3.x.x
