Ansible更新仍显示旧版本

我在Debian 8服务器上将ansible从2.0版升级到2.3.1，并按照Ansible提供的说明进行操作：

  1. 添加到来源列表： deb http://ppa.launchpad.net/ansible/ansible/ubuntu trusty main

  2. 运行以下命令：

    sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 93C4A3FD7BB9C367 sudo apt-get update sudo apt-get install ansible

    3. 我检查了which ansible，显示要指向/ usr / local / bin。 当我运行echo $ PATH时，我看到列出了/ usr / local / bin。我是否需要运行额外的步骤才能获得正确的Ansible版本？

    我没有输出。但是当我运行apt时，它成功更新为ansible 2.3.1

    更新：ansible最初是通过pip安装的。当我运行`pip install --upgrade ansible时，我得到：

    当我尝试运行apt-get install并运行/ usr / bin / ansible --version时，我得到了：

    Traceback (most recent call last):
  File "/usr/bin/ansible", line 46, in <module>
    from ansible.module_utils._text import to_text
ImportError: No module named _text

    理想情况下，我想通过pip升级，但我似乎无法让它运行。我会决定使用apt-get。

2 个答案:

答案 0 :(得分：3)

DEB软件包在/usr/bin/ansible安装ansible，我想你之前的安装不是来自DEB软件包（而是pip而是？），它解释了为什么你有两个版本的ansible。 /> 根据您PATH的定义，您没有获得新版本。

您应该清除之前的安装（pip uninstall？）

更新：pip install --upgrade失败，因为它正在尝试构建一些ansible依赖项的C绑定。

您应该卸载随pip安装的版本，然后重新安装DEB包：

pip uninstall --yes ansible
apt install --yes --reinstall ansible

从系统包和pip混合安装绝不是一个好主意...

答案 1 :(得分：1)

在我的情况下，pip list | grep <package name>显示了新版本，但\usr\bin内的全局包（可能是由rpm安装）仍然是旧版本。通常，您可以使用<package name> --version检查全局包版本。

要解决此问题，我必须使用sudo进行升级：sudo pip install -U <package name>

或者如果在virtualenv内，请在没有sudo的情况下安装，但使用-I忽略全局包：

pip install -I <package name>
