Re: [Maya-Python] Re: easy_install from Maya's python interpreter

[Marcus Ottosson]

With pip there is --target which installs to a given location. Not sure if
there’s an equivalent for ez_install.

ps. Not sure why your sending so many duplicate emails, but they each seem
slightly different than the last. Perhaps you are attempting to edit a post
on Google Groups? Just a heads up that that won’t work with a mailing list
as each reply get’s send to everyone who’s subscribed immediately.

[Maya-Python] Re: easy_install from Maya's python interpreter

[Paxton]

Marcus,
Right. but what i'm saying is that I am specifying a non-system directory 
C:\Users\USER\MyScripts\MYPACKAGE\extensions with '--to-dir' 
but it still errors out saying i cant write  to C:\Program 
Files\Autodesk\MAYAVERSION\Python\Lib\site-packages
even though i have specified a different directory...
it seems to use the directory specified to download the zip archive, but 
then it procedes to install to site-pacckages anyway.
Is there a better way of pointing ez_install to a specific directory?

here is the error i get:

The following error occurred while trying to add or remove files in the
installation directory:

[Errno 13] Permission denied: 'C:\\Program 
Files\\Autodesk\\Maya2016\\Python\\Lib\\site-packages\\test-easy-install-10980.write-test'

The installation directory you specified (via --install-dir, --prefix, or
the distutils default setting) was:

C:\Program Files\Autodesk\Maya2016\Python\Lib\site-packages\

Fredrik, to answer your question
"Is there a reason why you wouldn't want to go down such a route?"

I am, perhaps foolheartedly trying to build packages that can download 
their own latest versions as well as dependencies.

Right. but what i'm saying is that I am specifying a non-system directory

but it still errors out saying i cant write  to C:\Program

even though i have specified a different directory...
it seems to use the directory specified to download the zip archive, but 
then it procedes to install to site-pacckages anyway.
Is there a better way of pointing ez_install to a specific directory?

Re: [Maya-Python] Re: easy_install from Maya's python interpreter

[Marcus Ottosson]

You can't write to a system directory as a user without elevated
permissions. The same happens when you try and paste a file there via
Explorer. You'll need to run the console as administrator. Or change the
permission of the Maya directory, or install Maya in a user-writable
location.

Yea, I suppose on second thought, installing to site-packages is a bad 
idea.. 
that said, when I use the "--to-dir" arg for  ez_setup.py (and point it to 
a different path)

command = [get_maya_py_path(), ez_setup.__file__,'--to-dir',  
extensions_directory]
p = subprocess.Popen(command, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)


I still get permissions errors for mayas "site-packages" directory.
shouldn't that override the default site-packages path?
strange..

Re: [Maya-Python] Re: easy_install from Maya's python interpreter

[Robert White]

So I've not had any issues really using mayapy to handle compilation 
either. I was doing the custom build to potentially use it as a base for a 
CI/build system where I could avoid installing maya itself. Never did get a 
chance to finish the project, other issues came up and it keeps getting 
stuck in the middle of my queue.

As to how,  I found this walkthrough 
awhile
 
back, and adapted the process to work with VS2012.

Re: [Maya-Python] Re: easy_install from Maya's python interpreter

[Marcus Ottosson]

I’ve also built my own local versions of Python that match maya’s python
build environment, at least on windows. So I’ve got copies of 2.7 build
against VS2010 (Maya2014), and VS2012 (Maya2015/6). This has helped me when
compiling extension modules for python such as the P4API and PySide/PyQt
ect…

I’m curious, how come you compiled your own Python here, and didn’t use
mayapy? I’ve compiled packages with it before and can’t recall having any
issues with it.

Re: [Maya-Python] Re: easy_install from Maya's python interpreter

[Robert White]

So maya doesn't play to nicely with virtualenv, has to do with how it 
packages the standard lib into a zip-file.
Now you can transfer pure python libraries from a standard python install's 
virtualenv, and then just place that onto maya's pythonpath.

So I use a version of pip that I've installed to my local maya environment, 
then I integrate them into our development and distribution setup myself. 
Artists then use our deployed packages on their local machines, and for 
that we piggy back on maya's module system.

I've also built my own local versions of Python that match maya's python 
build environment, at least on windows. So I've got copies of 2.7 build 
against VS2010 (Maya2014), and VS2012 (Maya2015/6). This has helped me when 
compiling extension modules for python such as the P4API and PySide/PyQt 
ect...

 Hey Folks,

 I'm pretty close, but it looks like the system command to run

 I am pointing mayas python interpreter at ez_setup.py

 However.. I need to have this all happen from inside mayas python

 Any help super appreciated..

Re: [Maya-Python] Re: easy_install from Maya's python interpreter

[Fredrik Averpil]

I'm late to the party and have probably misunderstood what's going on
totally... but...

I'd create a virtual environment outside of Maya, pip install into it and
then inside of Maya I would make the virtualenv's site-packages available.
This would leave the Maya installation intact.

Is there a reason why you wouldn't want to go down such a route?
Do you need to use modules which needs to be compiled during pip install?

Cheers,
Fredrik

Re: [Maya-Python] Re: easy_install from Maya's python interpreter

[Justin Israel]

So,  what about Maya modules, which are meant to be distributed packages of
code?
Another option, what about distributing your tools with vendored
dependencies bundled in? What if a given studio doesn't have an internet
connection on the same machines as their production workstations?

[Maya-Python] Re: easy_install from Maya's python interpreter

[Paxton]

I totally agree, but expecting small animation studios to learn the 
intricacies of easy_install and pip in the context of Mayas python 
interpreter is not realistic (in my experience). 
Are there any other options for distributing tools (with dependencies) 
 that don't involve programmers on the receiving end?
