element-ui安装解决方案

　　在sepFour这个项目里面，安装element-ui时出现了这样子的一个错误

F:3 prcprcsepFour>npm i element-ui -S
npm ERR! Unexpected end of JSON input while parsing near '...rma-spec-reporter":"0'

npm ERR! A complete log of this run can be found in:
npm ERR!     e:softwareEXP
ode.js
ode_cache\_logs2018-09-12T06_13_21_597Z-debug.log

这时候有一个解决方案，就是执行下面的代码后再重新执行一次安装element-ui的命令：

npm cache clean --force

　　安装成功会出现下面的提示，可以看到安装的版本是+ element-ui@2.4.6：

Administrator@HTYYEML4JA3HA0P MINGW64 /f/03 prc/prc/noshery
$ npm i element-ui -S
npm WARN ajv-keywords@3.2.0 requires a peer of ajv@^6.0.0 but none is installed. You must install peer dependencies yourself.

+ element-ui@2.4.6

　　如果再安装不成功，可以试试加sudo提升权限进行-g全局安装。
