1、使用 vue-element-admin 安装依赖的时候报错；

npm ERR! code 128
npm ERR! An unknown git error occurred
npm ERR! command git --no-replace-objects ls-remote ssh://git@github.com/adobe-webplatform/eve.git
npm ERR! git@github.com: Permission denied (publickey).
npm ERR! fatal: Could not read from remote repository.

2、更改C盘下的C:\Users\用户名下找到.gitconfig；

[http]	sslverify = false
[url "https://github.com/nhn/raphael.git/"]insteadOf = git://github.com/nhn/raphael.git/

3、安装

npm install --registry=https://registry.npm.taobao.org

4、运行

npm run dev

如果报错再安装
To install them, you can run: npm install --save core-js/modules/es.error.ca

npm install core-js@3 --save

再次运行就可以了~
