我怀疑选择的pip包安装问题.但同样适用于基于Linux的系统. pip安装的 *** 作系统是否会有任何差异

解决方法 好吧,这似乎是一个已知的错误：

https://github.com/ansible/ansible/issues/31419

In Ansible 2.4.0,the module copy use symbolic links in the tests suite: 07001

circles -> ../subdir3 -> ../subdir2/subdir3

windows 10无法创建此目录树,因为路径太长.实际上解决的路径是：

test/integration/targets/copy/files/subdir/subdir1/circles/subdir1/circles/subdir1/circles/subdir1/circles/subdir1/circles/subdir1/circles/subdir1/circles/subdir1/circles/subdir2/subdir3/

错误报告以：

We do not support installing ansible directly on a windows machine. You will need a linux like operating system to install ansible on

解决方法

一个可能的解决方法是在pypi上下载轮,它不依赖于linux或其他什么,可能是纯python：

https://pypi.python.org/pypi/ansible/2.5.0a

(pip install ansible命令下载“source”.tgz archive,执行测试,…并且路径问题在测试中,所以让我们使用一个现成的预构建的bundle)

下载后,使用pip install path / to / the / wheel / file.whl

在我的windows 10计算机上成功测试并安装：

C:\Users\jotd>c:\Python27\Scripts\pip install C:\Users\jotd\Downloads\ansible-2.5.0a1-py2-none-any.whlProcessing c:\users\jotd\downloads\ansible-2.5.0a1-py2-none-any.whlRequirement already satisfIEd: PyYAML in c:\python27\lib\site-packages (from ansible==2.5.0a1)Collecting cryptography (from ansible==2.5.0a1)<a lot of package collecting...>Installing collected packages: IDna,pycparser,cffi,asn1crypto,ipaddress,cryptography,pynacl,bcrypt,pyasn1,paramiko,ansible  Running setup.py install for pycparser ... done  Running setup.py install for ipaddress ... doneSuccessfully installed ansible-2.5.0a1 asn1crypto-0.24.0 bcrypt-3.1.4 cffi-1.11.4 cryptography-2.1.4 IDna-2.6 ipaddress-1.0.19 paramiko-2.4.0 pyasn1-0.4.2 pycparser-2.18 pynacl-1.2.1

好的,已安装,但让我们尝试导入它：

C:\Users\jotd>c:\python27\pythonPython 2.7.12 (v2.7.12:d33e0cf91556,Jun 27 2016,15:24:40) [MSC v.1500 64 bit (AMD64)] on win32Type "help","copyright","credits" or "license" for more information.>>> import ansible>>>

作品！好极了！
