Question

在Mac上安装Ansible（10.11.6）我在这里http://docs.ansible.com/ansible/intro_installation.html进入“安装Python模块”部分并收到此错误：

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:

知道问题是什么吗？

Answer 1

如果您不介意安装用户，请致电pip install --user ansible并享受在El Capitan升级之后，Mac OS在安装全球软件包时遇到了一些麻烦。

Answer 2

USX上存在版本冲突，安装版本为6。已安装的版本（OSX附带的版本）可以使用，但是pip不知道它会起作用。不要尝试用pip安装六个。当您安装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6的冲突并假设已安装的版本可以正常工作。

Answer 3

OSX最近进行了更改，以便您可能会遇到（迟早）驻留在系统上的python模块与您需要安装的内容之间的不兼容性。 Ansible是一个很好的例子，因为它的依赖关系不再适合已安装的东西。

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，您正在创建一个泡泡，可以在其中安装和运行您的python版本及其模块。它是这样的：

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

$ ls -lah myenv
total 8
drwxr-xr-x   6 migueldavid  staff   204B 19 Aug 14:45 .
drwxr-xr-x+ 60 migueldavid  staff   2.0K 19 Aug 14:45 ..
lrwxr-xr-x   1 migueldavid  staff    63B 19 Aug 14:45 .Python -> /System/Library/Frameworks/Python.framework/Versions/2.7/Python
drwxr-xr-x  14 migueldavid  staff   476B 19 Aug 14:45 bin

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：

$ source myenv/bin/activate
(myenv)$ pip install ansible
Downloading/unpacking ansible
  Downloading ansible-2.1.1.0.tar.gz (1.9MB): 1.9MB downloaded
(...)

要摆脱这个＆＃34;沙盒＆＃34;，您只需键入

即可

$ deactivate

我希望这会有所帮助。
