我正试图在Ubuntu 12.04上用Python 2.7建立一个virtualenv使用vagrant但有相同的问题.似乎只有当从窗口发出"vagrant up"时才能看到这个问题.解决办法是什么？任何指针？

New python executable in .vagrant-env/bin/python
  Traceback (most recent call last):
  File "/usr/local/bin/virtualenv", line 9, in <module>
    load_entry_point('virtualenv==1.11.6', 'console_scripts', 'virtualenv')()
  File "/usr/local/lib/python2.7/dist-packages/virtualenv.py", line 824, in main
    symlink=options.symlink)

    os.symlink(py_executable_base, full_pth)
   OSError: [Errno 71] Protocol error

我按照这些说明(https://www.digitalocean.com/community/tutorials/how-to-install-and-use-graphite-on-an-ubuntu-14-04-server)安装statsd和graphite,但我遇到了下面陈述的问题.似乎这不是石墨问题而是python问题.有谁知道如何解决这个问题？

~/build > sudo service carbon-cache start
 * Starting Graphite backend daemon carbon-cache
Traceback (most recent call last):
  File "/usr/bin/carbon-cache", line 32, in <module>

我正在使用标准的异步发布者示例.我注意到发布者将永远在循环中继续发布相同的消息.所以我评论了来自publish_message的schedule_next_message调用来停止该循环.但我真正想要的只是当用户给它一个"message_body"和"Key"时,publissher才能开始发布

基本上是发布者发布用户输入.

我无法找到如何使发布者实时接收用户输入的任何示例或提示.我是raabitmq,pika,python等的新手

这是我正在谈论的代码片段: -

def publish_message(self):
    """If the class is not stopping, publish a message to RabbitMQ,
    appending a list of deliveries with the message number that was sent.
    This list will be used to check for delivery confirmations in the
    on_delivery_confirmations method.

    Once the message has been sent, schedule another message to be sent.
    The main reason I put scheduling in was just so you can get a good idea
    of how the process is flowing by slowing …

这样做时我得到了这个错误 sudo docker build .

我的Dockerfile看起来像这样:

ADD buzz /tmp/
# DOCKER-VERSION 0.3.4
#bunch of installs
RUN cd /tmp/ …

在使用Nova boot创建vm时,我正在为它提供一个用户数据脚本(cloud-init脚本).

我想知道的是,如何在云初始化脚本(或任何其他方式)中指定: - 安排一个cron作业每2小时运行一次

假设我想运行"du -s njain /"来每2小时查找一次目录的大小

我知道"runcmd"可以用来做一次..但我如何让它定期运行？du -s ../njain/

我刚刚开始学习Docker,大多数教程都是从以下开始的: docker run -t -i ubuntu /bin/bash

我无法使用它 docker run ubuntu /bin/bash

我能错过什么？
