npm错误：无法建立隧道套接字，因为= connect ETIMEDOUT
我有一个使用Rails框架的应用程序，并将AngularJs作为前端的一部分实现。
我已将所有内容推送到Heroku并安装了Heroku Toolbelt，但是当我尝试使用“heroku run rake db：migrate”迁移数据库时，我收到以下错误：
Installing core plugins heroku-cli-addons, heroku-apps, heroku-fork, heroku-git, heroku-local, heroku-run, heroku-status... Error installing package. Try running again with GODE_DEBUG=info to see more output. ! `run` is not a heroku command. ! Perhaps you meant `-h`, `2fa`, `auth`, `join`, `open`, `orgs`, `pg`, `ps` or `rake`. ! See `heroku help` for a list of available commands. 然后我运行命令“GODE_DEBUG = info heroku run rake db：migrate”并收到此错误：

删除代理设置解决了以下问题：
npm config rm proxy
npm config rm https-proxy
npm config set registry=http://registry.npmjs.org/ npm config set strict-ssl false
它对我有用！
