Python easy_install throws chmod-error


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

To install PyCrypto and Fabric, i used easy_install, as recommended in the guide, but both failed, returning an chmod-error:

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

Traceback (most recent call last):

 [... 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

I don't know much about this chmod-thing, but I thought there is no chmod in Windows?

How can i get easy_install to actually work?

I postet a similar question here, where (thanks to @J.F. Sebastian) I found a workaround to install those packages without fabric. But now I do want to know, how to actually solve the problem I'm having with easy_install.


Solution

  • Log in as the administrator of your machine. chmod refers to permissions for accessing directories, and in this case, I have a feeling python is complaining about Windows 7's UAC (user account control). Creating directories in C:\ requires elevated permissions in Windows.
