尝试在服务器上安装 ansible 1.9。我已经安装了 ansible-1.9 PPA。以下是我上次尝试的相关信息：

我遗漏了什么？这是 Ansible PPA 的问题吗，还是我错过了某个步骤？
答案1
问题原来是之前（无意的）安装 2.1.1.0 时遗留的垃圾，没有用“apt-get purge”删除。遇到此问题的其他任何人应检查：/usr/local/bin 和 /usr/local/lib/python2.7/dist-packages 中是否有任何与 ansible 相关的后清除内容。我能够通过启动全新的 Ubuntu 实例来安装正确的版本，但如果您清除任何可能遗留的内容，您应该不会遇到任何问题。
