M上的Ansible安装错误

Question

在Mac上安装Ansible（10.11.6），我进入“安装Python模块”部分http://docs.ansible.com/ansible/intro_installation.html并得到以下错误：

sudo pip install paramiko PyYAML Jinja2 httplib2 six

... lots of downloading ...

Installing collected packages: pyasn1, pycparser, cffi, setuptools, idna, ipaddress, enum34, cryptography, paramiko, PyYAML, MarkupSafe, Jinja2, httplib2
Running setup.py install for pycparser ... done
Found existing installation: setuptools 1.1.6
Uninstalling setuptools-1.1.6:

OSX最近做了一些更改，因此您可能会（迟早）遇到驻留在系统中的python模块与您需要安装的东西之间的不兼容。 Ansible是一个很好的例子，因为它的依赖关系不再适合于已经安装的内容。在

干净的解决方案是使用虚拟环境： https://virtualenv.pypa.io/en/stable/userguide/#usage

很简单，您正在创建一个气泡，在其中安装和运行您的python版本及其模块。事情是这样的：

$ virtualenv myenv
New python executable in myenv/bin/python
Installing setuptools, pip...done.

$ ls -lah myenv

drwxr-xr-x   3 migueldavid  staff   102B 19 Aug 14:45 lib

然后激活虚拟环境并安装所需的任何内容：

要离开这个“沙盒”，你只需输入

$ deactivate

我希望这有帮助。在

如果您不介意用户安装，请致电pip install user ansible并享受。

Answer 3

USX上的版本与已安装的版本6存在版本冲突。安装的版本（OSX附带的版本）可以工作，但是pip不知道它能工作。不要试图用pip安装6。在安装Ansible时，请使用以下命令：

sudo -H pip install ansible  upgrade  ignore-installed six

这告诉pip忽略与six的冲突，并假设安装的版本可以工作。在
