[Pythonmac-SIG] Installing modules with py2app
Hello
I have a script that installs Python, and then installs some modules with:
subprocess.call("python setup.py install")
The script works on Windows with py2exe, but gives me this error when using
py2app:
File setup.py
from distutils.core import setup
ImportError: No module named distutils.core
I tried explicitly including distutils when building the .app bundle, with
python setup.py py2app --packages distutils (and several variations of
--includes), but then I get this error:
error: invalid command 'install'
What do I need to do to make this work on mac?
Thanks!

Re: [Pythonmac-SIG] Installing modules with py2app
Did you build the app bundle with the Python that came with OSX, or did you
install a separate Python install from python.org and use that? You have to
do the latter; py2app's not allowed to include components of the operating
system in the apps it generates. Windows gets around this problem by not
having a standard Python install.

Hi
I am using a separate Python install (ActivePython 2.6 ), so that's not it
Thanks

Do you have distutils installed? It usually doesn't come bundled with
Python. It can be installed with easy_install:
easy_install distutils

Try debugging this issue by printing sys.path, and check if
distutils/core... exists in one of them:
subprocess.call('python -c "import sys; print((sys.prefix, sys.path))"')

Re: [Pythonmac-SIG] Installing modules with py2app
Hi Sridhar
Your suggestion to debug this problem started me in the right path. I found a
workaround for the issue.
First, I explicitly included distutils in my py2app bundle. With that, the
error I get is:
usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]
or: setup.py --help [cmd1 cmd2 ...]
or: setup.py --help-commands
or: setup.py cmd --help
error: invalid command 'install'
I modified the included distutils files, and managed to get this stack trace
Traceback (most recent call last):
File "distutils/dist.py", line 837, in get_command_class
__import__ (module_name)
File "distutils/command/install.py", line 21, in
from site import USER_BASE
cannot import name USER_BASE
The site.py included in the bundle has this comment: This is stripped down and
customized for use in py2app applications
So apparently, py2app is removing USER_BASE and USER_SITE from site.py. I am
not sure why it does that, but it is preventing the installation of modules
with py2app.
I worked around it by modifying the included site.py to declare USER_BASE and
USER_SITE after generating the .app bundle.
I think this might be a bug in py2app, but would like to know your input on
this.
Regards,

I am trying to install modules into the system python.
The problem with my solution (which I hadn't notice); is that modules are
getting installed into the .app bundle instead.
The problem is that, even though subprocess.call("python setup.py install")
picks up the system python (sys.executable has the expected value), it still
loads the modules from the site-packages.zip in the .app bundle.
How can I make this new python process load the modules from system
site-packages folder?
Thanks

I don't think it's a bug -- you may have some problems with this. I'm
not sure I quite get what distutils is doing with USER_BASE and
USER_SITE, but I suspect that they are using them to figure out where to
install stuff. That should be a function of the python you are
installing to. A py2app bundle isn't usually installing stuff into itself.
How are you using distutils in this case? Are you installing stuff into
the app bundle? Or into a system python? If a system python, you should
probably use the system python's distutils (and thus its site.py) to do
the work.
If you are installing into the app bundle (cool idea!), then you'll need
to make sure that USER_BASE and USER_SITE are set correctly at run time
for where the user happens to have put the py2app bundle.

I suspect that you are getting environment variables set by py2app,
rather that the user's raw environment.
Maybe it shouldn't be a subprocess -- what happens if you do a simple:
os.system("python setup.py install")
you also may need to make sure the working dir is correct:
os.system("cd the/full/path/to/setup; python setup.py install)

Re: [Pythonmac-SIG] Installing modules with py2app
Try putting env={} in subprocess
For MacOS (and probably Linux if it were running through Freeze or the like),
you need to pass env as an empty dict. For Windows and py2exe, you pass env as
None.
I don't know if this post will get through as I'm not intending to subscribe to
this list, but I thought I'd try sending an answer as I came across your post.
Cheers,
Mike
