在Windows 7上安装Python Fabric时出现问题

Question

I'm trying to install Python Fabric on Windows 7 using the guide from Getting Python and Fabric Installed on Windows .

What i did so far:

• Installed Python 2.7 to C:\\Python27
• Added the Python-Directory and Python/Scripts to the Windows System Paths
• Installed SetupTools
• Installed MinGW
• Added MinGW-Directory to the System Path
• Modified the distutils.cfg to match the MinGW-Path

This seemed to work fine until now. When I try to install Fabric via easy_install Fabric it starts to download the files, but then i get an chmod error .

Using c:\python27\lib\site-packages\fabric-1.3.4-py2.7.egg

The command "chmod" is spelled wrong or could not be found.

Traceback (most recent call last):
 File "C:\Python27\Scripts\easy_install-script.py", line 8, in <module> load_entry_point('setuptools==0.6c12dev-r88846', 'console_scripts', 'easy_install')()  
 File "C:\Python27\lib\site-packages\setuptools-0.6c12dev_r88846-py2.7.egg\setuptools\command\easy_install.py", line 1712, in main  

 ... lots and lots of lines... (if they are relevant, I'll post them)

 File "C:\Python27\lib\distutils\dist.py", line 972, in run_command cmd_obj.run()  
 File "setup.py", line 269, in run  
RuntimeError: chmod error  

Any suggestions to solve the problem?

I have just managed to install fabric on win7 box, using information from various places in the net. That was really annoying, so just to save others frustration I put together the following list.

1. Install pip http://www.pip-installer.org/en/latest/index.html (that's easy, follow the guide on the web site, goes without problems)
2. run from command line pip install fabric - you'll get errors, some stuff about missing bat files, etc. while installing pycrypto.
3. Download precompiled pycrypto package from http://www.voidspace.org.uk/downloads/ for your version of Python , for instance for 2.7 it is http://www.voidspace.org.uk/downloads/pycrypto-2.1.0.win32-py2.7.zip
4. run again from command line pip install fabric - this time everything seems to be ok, until you try to run fabric script. It will complain about "No module named win32api", etc.
5. Install that missing win32api from http://sourceforge.net/projects/pywin32/files/pywin32/ - first choose a build version (newest, probably) and then again .exe file for your Python version.

And you are done, fabric should work ok.

您是否尝试过非扩展的软件包扩展包的非官方Windows二进制文件中的二进制安装程序： 基本分发可能包含Fabric 。

Answer 3

If you're using virtualenv, you need to add one point to Piotr Kochanski's answer: when creating the virtualenv, allow it to access the system packages so it can see pycrypto. By default it disallows this.

These steps worked for me:

1. Install pycrpyto binary from http://www.voidspace.org.uk/python/modules.shtml#pycrypto .

2. Create a virtual env that can access the system packages. For example:

   c:\\Python27\\Scripts\\virtualenv.exe --system-site-packages c:\\Proj\\virtualenv

3. pip install fabric

Answer 4

1.Create a virtualenv (I usually put all mine on the desktop)

2.Download the binary of pycrypto (matching your installed python version and architecture -- no support for python3 as of now) - http://www.voidspace.org.uk/python/modules.shtml

3.Navigate to the easy_install executable (under Lib\\site-packages) within the virtualenv folder you created and run the pycrypto install - 'easy_install C:\\path\\to\\the\\download\\pycrypto-2.6.win-amd64-py2.7.exe'

4.Activate the virtualenv and 'pip install fabric'
