瘦 Web 服务器:“start_tcp_server":git 分支结帐后没有接受器(运行时错误) [英] Thin web server: `start_tcp_server': no acceptor (RuntimeError) after git branch checkout

问题描述

Rails 3.2.0 应用程序，适用于本地和 Heroku cedar 堆栈上的瘦 Web 服务器.

A Rails 3.2.0 app, working fine with Thin web server, both locally and on Heroku cedar stack.

之后:

$ git branch work
$ git checkout work
$ rails server

我明白了:

=> Booting Thin
=> Rails 3.2.0 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
>> Thin web server (v1.3.1 codename Triple Espresso)
>> Maximum connections set to 1024
>> Listening on 0.0.0.0:3000, CTRL+C to stop
Exiting

from script/rails:6:in `<main>'

此外，当我这样做时:

sudo bundle exec rails server thin -p 3000

我明白了:

from /Users/peter/.rvm/gems/ruby-1.9.3-p125/bin/bundle:18:in `<main>'

我安装了 bundler 1.0.22.更新并安装了它.似乎没有任何效果.有什么想法吗?

I have bundler 1.0.22 installed. Updated and installed it. Nothing seems to work. Any ideas?

推荐答案

这对我有用.查找(僵尸?)服务器(在服务器运行的情况下退出终端时可能会发生):

This works for me. Find (zombie?) server (can happen when quitting terminal with server running):

$ ps ax | grep rails

如果它返回类似:

33467 s002 S+ 0:00.00 grep rails
33240 s003 S+ 0:15.05 /Users/Arta/.rbenv/versions/1.9.2-p290/bin/ruby script/rails s -p 3000

杀死它，然后重新运行:

kill it, and run anew:

$ kill -9 33240
$ rails s
