如何修复 Windows上的pip安装失败,错误如下.尝试安装ansible时出现此错误.

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安装的操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:Usersjotd>c:Python27Scriptspip install C:UsersjotdDownloadsansible-2.5.0a1-py2-none-any.whl
Processing c:usersjotddownloadsansible-2.5.0a1-py2-none-any.whl

好的,已安装,但让我们尝试导入它：

C:Usersjotd>c:python27python
Python 2.7.12 (v2.7.12:d33e0cf91556,Jun 27 2016,15:24:40) [MSC v.1500 64 bit (AMD64)] on win32

>>> import ansible
>>>

作品！好极了！
