npm安装错误

Question

我正在尝试使用以下命令安装一个用于缩短网址的位节点模块

sudo npm install bitly --save

并收到以下错误 -

npm ERR! path /var/www/frontend/node_modules/request/node_modules/.bin/uuid
npm ERR! code EEXIST
npm ERR! Refusing to delete /var/www/frontend/node_modules/request/node_modules/.bin/uuid: is outside /var/www/frontend/node_modules/request/node_modules/node-uuid and not a link
npm ERR! File exists: /var/www/frontend/node_modules/request/node_modules/.bin/uuid
npm ERR! Move it away, and try again.

非常感谢任何帮助。提前谢谢。
