我试图使用omh.h头文件,我意识到它丢失了.我尝试使用brew在我的mac上重新安装gcc.这是我在安装结束时收到的消息.

..
GCC has been built with multilib support. Notably, OpenMP may not work:
  https://gcc.gnu.org/bugzilla/show_bug.cgi?id=60670
If you need OpenMP support you may want to
  brew reinstall gcc --without-multilib
==> Summary
  /usr/local/Cellar/gcc/4.9.2_1: 1156 files, 203M

它表明,如果我需要OpenMP支持,我需要安装brew reinstall gcc --without-multilib.我无法理解其含义--without-multilib.它与简单地安装gcc有什么不同？

并且显然brew reinstall gcc --without-multilib需要永远运行并且brew uninstall gcc && brew install gcc闪电般快速.

这似乎有效,但它是否脆弱？我希望将files命令中的所有者和组设置为someguy.我希望能够使用,{{ remote_user }}但这不起作用.

这是一个显示我的意思的示例剧本.

---
- hosts: foobar
  remote_user: someguy
  tasks:
    - name: configure /usr/src/foo
      file: 
        dest: /usr/src/foo
        state: directory
        owner: {{ ansible_ssh_user }}
        group: {{ ansible_ssh_user }}
        recurse: yes
      sudo: yes

这不起作用:

---
- hosts: foobar
  remote_user: someguy
  tasks:
    - name: configure /usr/src/foo
      file: 
        dest: /usr/src/foo
        state: directory
        owner: {{ remote_user }}
        group: {{ remote_user }}
        recurse: yes
      sudo: yes

一个或多个未定义的变量:'remote_user'未定义

我在python 3.3上,我必须测试一个使用callsubprocess.py 的方法.

我试过了:

subprocess.call = MagicMock()

with patch('subprocess.call') as TU_call:

但在调试模式下,我发现python有效调用 subprocess.call

我有一个Web应用程序,通过Web套接字接收位置数据.我已经通过自制软件在我的mac上安装了rabbitmq来在本地运行Web套接字.我正在尝试启用rabbitmq_web_stomp,但我收到此错误:`

rabbitmq-plugins enable rabbitmq_web_stomp
Error:
{:plugins_not_found, [:rabbitmq_management_visualiser]

当我跑 rabbitmq-plugins list
