在公司内网利用vue-cli-3.x，create项目时，总是提示失败：
RequestError: Error: connect ETIMEDOUT 151.101.72.162:443

解决办法：
在request.js（路径：npm\node_modules@vue\cli\lib\util）中手动添加局域网的代理，具体修改如下：
const request = require('request-promise-native')
module.exports = {
async get (uri) {
const reqOpts = {
method: 'GET',
resolveWithFullResponse: true,
json: true,
uri,
proxy: 'http://<your.proxy.info>:8080'
}
return request(reqOpts)
}
}
