Unmodified environment for subprocesses
by Tuomo Valkonen Jan. 22, 2018

Jan. 22, 2018

I’m working on a frontend to Borg backup, based on rumps (http://rumps.readthedocs.io/en/latest/ <http://rumps.readthedocs.io/en/latest/>). For using the keychain, etc., it would be useful to turn the frontend into a standalone app. So I tried to do that with py2app, but when running my app this way, borg subprocesses fail: module ‘borg’ not found. If I pass a modified environment to subprocess.Popen, as follow, then things will work: env=os.environ.copy() del env['PYTHONPATH'] del env['PYTHONHOME'] But of course this also will fail on system where the variables are set in the default environment. My question then is, is there a clean way to restore the original environment, before py2app changed it? Tuomo

Problem with pip
by Shawn Tolidano Jan. 19, 2018

Hi, I have cffi==1.11.4 in my requirements file (and in my transitive file, by extension). I am running High Sierra, my python is 2.7.14 and comes from Brew. /usr/local/Cellar/python/2.7.14/Frameworks/Python.framework/Versions/2.7/lib/python2.7/ I create a venv and upgrade pip (to 9) and then: ./build-support/python/venvs/pydeps-wheel/bin/pip install -r 3rdparty/python/requirements.transitive.txt In this file are lots of requirements, but that’s not relevant (I don’t think). One of them is cffi==1.11.4. When I run this, this happens: Collecting cffi==1.11.4 (from -r 3rdparty/python/requirements.transitive.txt (line 22)) Downloading cffi-1.11.4-cp27-cp27m-macosx_10_6_intel.whl (238kB) 100% |████████████████████████████████| 245kB 2.2MB/s Note the 10.6. Also note this: ./build-support/python/venvs/pydeps-wheel/bin/python -c "import distutils.util; print(distutils.util.get_platform())" macosx-10.13-x86_64 So - to my knowledge, it has NO BUSINESS using the 10.6 as a compatible wheel and should instead download the source. So I empty my requirements file and leave ONLY cffi==1.11.4 I recompute (with pip freeze) and end up with cffi, setuptools, wheel, and pycparser. I run the SAME install command as above. And get this: Collecting cffi==1.11.4 (from -r 3rdparty/python/requirements.transitive.txt (line 2)) Using cached cffi-1.11.4.tar.gz And ultimately, it builds this: Dist/wheels/cffi-1.11.4-cp27-none-macosx_10_13_x86_64.whl 1) Why does it think 10.6 is a valid wheel? 2) How do I fix this?

Re: [Pythonmac-SIG] Building python-based Mac app with py2app, creating an installer, generates failing installer

Thanks for your replies. I managed to come up with something that worked! I had to do a couple of things, for those that are interested… I needed to upgrade py2app to version 0.8, which fixed a problem in the version we were using (0.7.3) where file permissions were not preserved when copying files into the application bundle. As an aside, I tried the most recent version (0.14), but it created a new and different problem (which I can’t recall at the moment). In the pkgbuild command, I had been using —root instead of —component when creating the component package from the application. Using —root made a package that expected to install its own python, which is why it was trying to mess with the /System Python.Framework directory. Using —component made things work. :) Hope may this will help someone someday. -EricF > On Dec 23, 2017, at 10:38 AM, Sean Wayland <seanwayland(a)gmail.com> wrote: > > The other thing I remember is that tkinter is incompatible with py2app.. > > On Dec 23, 2017 10:21 AM, "Sean Wayland" <seanwayland(a)gmail.com <mailto:seanwayland@gmail.com>> wrote: > I tried this once.
