如何克服 - 在windows上使用文件名或扩展名失败的Windows上安装ansible

Question

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

Answer 1

好吧,这似乎是一个已知的错误:

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

在Ansible 2.4.0中,模块副本在测试套件中使用符号链接:https://github.com/ansible/ansible/tree/devel/test/integration/targets/copy/files/subdir/subdir1

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:

我们不支持直接在Windows机器上安装ansible.您将需要一个类似Linux的操作系统来安装ansible

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

(该pip install ansible命令下载"source".tgz存档,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建包)

下载后,请使用 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.whl
Processing c:\users\jotd\downloads\ansible-2.5.0a1-py2-none-any.whl
Requirement already satisfied: PyYAML in c:\python27\lib\site-packages (from ansible==2.5.0a1)

好的,已安装,但让我们尝试导入它:

C:\Users\jotd>c:\python27\python
Python 2.7.12 (v2.7.12:d33e0cf91556, Jun 27 2016, 15:24:40) [MSC v.1500 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import ansible
>>>

作品!好极了!

Answer 2

我在没有使用 pip 的情况下安装了 ansible，这对我来说似乎非常简单。

脚步：

• 从https://pypi.org/project/ansible/下载压缩的 .tgz 存档

• 打开 7-zip，右键单击以管理员身份运行并解压。<- 由于符号链接，管理是必需的

• 在文件夹中打开管理控制台并运行：

  python setup.py 安装

现在 ansible 已安装在 Windows 上。
