这是我第一次遇到这样的错误:

it is my first time to encounter such error(s):

Running `rake db:migrate` attached to terminal... up, run.8524 ! Heroku client internal error. ! Search for help at: help.heroku ! Or report a bug at: github/heroku/heroku/issues/new Error: Operation timed out - connect(2) (Errno::ETIMEDOUT) Backtrace: /usr/local/heroku/lib/heroku/client/rendezvous.rb:39:in `initialize' /usr/local/heroku/lib/heroku/client/rendezvous.rb:39:in `open' /usr/local/heroku/lib/heroku/client/rendezvous.rb:39:in `block in start' /usr/local/heroku/ruby/lib/ruby/1.9.1/timeout.rb:68:in `timeout' /usr/local/heroku/lib/heroku/client/rendezvous.rb:31:in `start' /usr/local/heroku/lib/heroku/command/run.rb:113:in `rendezvous_session' /usr/local/heroku/lib/heroku/command/run.rb:100:in `run_attached' /usr/local/heroku/lib/heroku/command/run.rb:21:in `index' /usr/local/heroku/lib/heroku/command.rb:206:in `run' /usr/local/heroku/lib/heroku/cli.rb:28:in `start' /usr/local/heroku/bin/heroku:24:in `<main>' Command: heroku run rake db:migrate --app oppcis Version: heroku-toolbelt/2.35.0 (x86_64-darwin10.8.0) ruby/1.9.3

我已经有一段时间没有使用 heroku 了......在大回归之后，我遇到了这个错误.

I've been out for awhile in using heroku... and after the big comeback, I encountered this error.

就目前的 Heroku 新闻而言，我已经过时了.

I am outdated already in terms of present Heroku news.

我希望有人能给我一个建议、解决方案或涉及的问题.

I hope somebody could give me a suggestion, solution or issues involved.

谢谢.

推荐答案

尝试在后台"运行

heroku run:detached rake db:migrate

您也可以尝试 heroku 故障排除，因为它似乎是连接问题.

You can also try heroku troubleshooting, as it appears to be a connection problem.

heroku run rails console telnet rendezvous.runtime.heroku 5000

如果它不起作用，您可能有防火墙阻止了您与 heroku 的连接.

If it doesn't work, you probably have a firewall blocking your connection to heroku.
