问题原因：
执行npm install到仓库拉取代码时需要认证，现在是认证不通过，因此报错
现象：
浏览器直接访问仓库，然后使用公司给的账号和密码登录是正常的，说明账号密码是正确的
http://192.168.xx.xxx:8074/repository/npm-internal/.
解决方法：
先执行npm config list,找到.npmrc的位置
PS D:\GitworkspaceUi\gisquest-cloud-ui-workcenter> npm config list
; cli configs
metrics-registry = "http://192.168.xxx.xxx:8073/repository/npm-all/"
scope = ""
user-agent = "npm/6.14.12 node/v14.16.1 win32 x64"; userconfig C:\Users\Administrator\.npmrc
方法一（网上的仅供参考）：
打开后大概如下效果
删掉第二行
//192.168.xx.xx:8073/repository/npm-all/:_authToken=NpmToken.1ee55b58-d164-3b43-a731-xxxxxx
重新执行登录
npm login --registry=http://192.168.xx.xxx:8073/repository/npm-internal/
方法二：直接删掉.npmrc
npm config set registry http://192.168.xx.xxxx:8073/repository/npm-all/
npm config set //192.168.xx.xxx:8073/repository/npm-all/:_authToken=NpmToken.1ee55b58-d164-3b43-a731-xxxxx
说明：上面第一条命令是注册仓库的位置，第二条是仓库的的认证token
这里的token是从同事（他那里是正常）.npmrc文件中复制过来的
然后执行npm install正常了
