yum install python-setuptools to install easy_install and ansible - errors: AttributeError: other Python Errors
yum install python-setuptools to install easy_install and ansible - errors: AttributeError: other Python Errors
目标：在 RedHat Linux 机器上安装 ansible。
关于这一切如何开始的小概述：
当我的 Linux 机器是 RedHat 5.9 (Tikanga) 时，默认 python 安装的版本是 2.4。我已尽力而为，但由于 Ansible 要求 python >= 2.6，所以无法正常工作。我尝试在 Linux 5.9 版本上安装 2.7.9，但随后事情开始变得非常快。
我确实在 Linux 5.9 上尝试了 2.7.9 python 作为 "make altinstall" 而不是安装，但是在 运行 yum / etc 系统级别时仍然有很多错误命令。
出现的错误很少（有或没有 运行 sudo）：
# sudo pip install ansible

终于幸运了，我想，让我们从头开始重新安装 python（所以我 运行 yum erase python， !!! 当心 !!!!)，据我所知，这是我 运行 根据我的经验，稍有疏忽的最佳命令。最终结果：我最终在这里创建了一个新产品：http://www.keepcalmandcarryon.com/creator/?shortcode=qCsMlpyc
总之, ...现在，我用较新版本的 RedHat（圣地亚哥 6.6 版）恢复了服务器，这次默认 Python 是: 2.6.6.
当前情况：这就是我现在面临的问题，在安装了 Python 2.6.6 的 RH Linux 5.9 上。
我是 运行: sudo easy_install pip 但是我得到一个错误:
sudo: easy_install: command not found
为了解决以上问题，我现在运行：sudo yum install python-setuptools
它找到了...但向我显示了一些错误。

任何想法，我怎样才能在我的 Linux 机器 6.6（现在）上获得 easy_install、pip 或 ansible。
谢谢。
运行 以下命令修复所有问题，现在终于安装了 ansible：
wget http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
sudo rpm -ivh epel-release-6-8.noarch.rpm
但是在这个阶段，我得到了 Jinja2 的错误...如下所示：ImportError: No module named setuptools

Traceback (most recent call last):

-bash-4.1$
为了解决上述问题并继续，我 运行 使用以下命令获取 python-setuptools（安装 easy_install）
wget https://bootstrap.pypa.io/ez_setup.py -O - | sudo python
太好了，现在我的机器上安装了 easy_install。
-bash-4.1$ which easy_install

此时，我想安装ANSIBLE，所以我运行如下：

OP 中显示的大多数错误都是由于版本不匹配造成的。例如。 except: XXX as obj 语法为 introduced in 2.6.
我预计情况会更加复杂，因为您同时安装了 2.4 和 2.6，然后您使用 sudo 来安装东西。
最好以 root 身份打开交互式 shell，在通过 yum 或 pip 安装这么多 python 模块之前正确设置 PATH 和 PYTHONPATH，这样你知道哪些模块安装到哪个前缀。
yum erase python 是愚蠢，因为你可能是通过艰难的方式学到的。
所有这些都是 yum 配置错误：

总的来说ansible installation instructions还是比较靠谱的
--编辑--
The only thing is even when PATH was set to use 2.7.9 python (for
which python), and PYTHONPATH / PYTHONHOME were set, Linux 5.9 version
was still picking python version 2.4 site packages and the utilities
in Linux 5.9 are tightly dependent upon python 2.4. Under /usr/xxx
there no folders for LIB for python 2.7.9 at that time until I
switched the whole Linux to 6.6 version. And instead of using "make
install" for manually installing python, I used "make altinstall" so
that both can sit side by side. – Arun Sangal
在 RHEL 5.x 上：/usr/bin/python 将保持 2.4，即使您安装 2.6+（这将转到 /usr/bin/python2.6 或 /usr/bin/python26 或类似的东西。所以默认python 仍然是 2.4（即使安装了 2.6+）
在 RHEL 6.x 上：python 默认情况下未安装 2.4。所以 /usr/bin/python 默认为 2.6。所以默认的python是2.6.
大多数 utilities/scripts 将与 /usr/bin/python 一起执行，因此 你感觉像 'utilities in Linux 5.9 are tightly dependent upon python 2.4'.
通常问题是为 2.6+ 编写的脚本在 RHEL 5.x 上使用 /usr/bin/python 执行，即 python 2.4。 “AFAIK”相反（运行 2.4 脚本与 2.6 解释器）更兼容（不完全）。
目标：在 RedHat Linux 机器上安装 ansible。

OP 中显示的大多数错误都是由于版本不匹配造成的。例如。 except: XXX as obj 语法为 introduced in 2.6.
我预计情况会更加复杂，因为您同时安装了 2.4 和 2.6，然后您使用 sudo 来安装东西。
最好以 root 身份打开交互式 shell，在通过 yum 或 pip 安装这么多 python 模块之前正确设置 PATH 和 PYTHONPATH，这样你知道哪些模块安装到哪个前缀。
yum erase python 是愚蠢，因为你可能是通过艰难的方式学到的。
所有这些都是 yum 配置错误：

总的来说ansible installation instructions还是比较靠谱的

The only thing is even when PATH was set to use 2.7.9 python (for which python), and PYTHONPATH / PYTHONHOME were set, Linux 5.9 version was still picking python version 2.4 site packages and the utilities in Linux 5.9 are tightly dependent upon python 2.4. Under /usr/xxx there no folders for LIB for python 2.7.9 at that time until I switched the whole Linux to 6.6 version. And instead of using "make install" for manually installing python, I used "make altinstall" so that both can sit side by side. – Arun Sangal
在 RHEL 5.x 上：/usr/bin/python 将保持 2.4，即使您安装 2.6+（这将转到 /usr/bin/python2.6 或 /usr/bin/python26 或类似的东西。所以默认python 仍然是 2.4（即使安装了 2.6+）
在 RHEL 6.x 上：python 默认情况下未安装 2.4。所以 /usr/bin/python 默认为 2.6。所以默认的python是2.6.
大多数 utilities/scripts 将与 /usr/bin/python 一起执行，因此 你感觉像 'utilities in Linux 5.9 are tightly dependent upon python 2.4'.
通常问题是为 2.6+ 编写的脚本在 RHEL 5.x 上使用 /usr/bin/python 执行，即 python 2.4。 “AFAIK”相反（运行 2.4 脚本与 2.6 解释器）更兼容（不完全）。
