Node.js 在ubuntu上安装hubot时出错

当我运行yo hubot时，出现以下错误

npm ERR! argv "/usr/local/bin/node" "/usr/local/bin/npm" "install" "hubot"
"hubot-scripts" "hubot-diagnostics" "hubot-help" "hubot-heroku-keepalive" "hubot-google-images"
"hubot-google-translate" "hubot-pugme" "hubot-maps" "hubot-redis-brain"
 "hubot-rules" "hubot-shipit" "--save"

---

为什么会这样？我试过运行

sudo npm install hubot rules

，但似乎不起作用。请帮忙

结果表明，您需要拥有

~/.npm

目录。您可以运行此命令来执行此操作：

$sudo chown-R$（whoami）“$HOME/.npm”
