我在 Debian 8 服务器上将 ansible 从版本 2.0 升级到 2.3.1，并按照 Ansible 提供的说明进行操作:
添加到来源列表:
deb http://ppa.launchpad.net/ansible/ansible/ubuntu trusty main运行以下命令:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 93C4A3FD7BB9C367 sudo apt-get 更新 sudo apt-get install ansible
我检查了which ansible，显示指向/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来获取正确版本的 Ansible？
我没有输出。但是当我运行 apt 时，它成功更新到 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:

----------------------------------------
Cleaning up...
Command python setup.py egg_info failed with error code 1 in /tmp/pip-build-jyjjV6/pynacl
Storing debug log for failure in /root/.pip/pip.log
当我尝试运行 apt-get install 和运行/usr/bin/ansible --version 时，我得到:
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。不过，我会选择使用 apt-get。
最佳答案
DEB 包在 /usr/bin/ansible 中安装 ansible，我猜你之前的安装不是来自 DEB 包(而是 pip？)并且它解释为什么你有 2 个版本的 ansible。
根据您的 PATH 定义，您不会获得新版本。
您应该清理以前的安装(pip uninstall？)
更新:pip install --upgrade 失败，因为它正在尝试构建一些可依赖的 C 绑定(bind)。
你应该卸载用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 混合安装从来都不是一个好主意...
