I failed during building wheel for pyobjc-framework-Cocoa, relevant part from error log:

    I have the same issue with 10.11.4 and Xcode Version 7.3 (7D175). I get:

    1. Failed building wheel for pyobjc-framework-CoreLocation
    2. Failed building wheel for pyobjc-framework-MapKit
    3. Failed building wheel for pyobjc-framework-Quartz

    3 errors generated. error: command 'clang' failed with exit status 1

    I also get this error:

    error: command 'gcc' failed with exit status 1

    ,when I try 'pip install -U pyobjc' instead of 'env CC=clang pip install -U pyobjc'

    What python version are you using? In particular, are you using Anaconda or a Python where sysconfig.get_config_var('MACOSX_DEPLOYMENT_TARGET') returns an OSX release before 10.6?

    If so: set "MACOSX_DEPLOYMENT_TARGET=10.6" before installing (or even set it to 10.10 if you don't intend to install the binaries on older OSX releases).

    PyObjC 3.2 will have a proper fix for this.

  3. Vishal Kasera

    sysconfig.get_config_var('MACOSX_DEPLOYMENT_TARGET') returns '10.10' for me. Still having same problem.

    Python version: 2.7.11

  4. wooque reporter

    Latest Python from Homebrew, unfortunately I'm currently on vacation til May 4th, but as soon as I come back I will check what sysconfig.get_config_var('MACOSX_DEPLOYMENT_TARGET') is returning

    I ran into the exact same issue trying to install pyatom. Per I had to install pyobj-core (which worked) then pyobj ( did not work, had the exact same stacktrace as described above).


    ProductName: Mac OS X / ProductVersion: 10.10.5 / BuildVersion: 14F1713

    xcodebuild -version

    Xcode 7.2.1 / Build version 7C1002

    python --version



    import sysconfig



    Command that led to the same stacktrace:

    pip install -U pyobjc

    Per stdout, this is installing version "3.1.1".

    Any timeline for when will PyObjC 3.2 be released ?

  6. Nate McFeters

    Having the exact same issue as the others. To answer your question to Marc C, I'm not using homebrew for this... I have pyenv to manage my instances, and I'm having issues with all instances. I believe that this behavior changed when I recently updated xcode.

  7. Ronald Oussoren repo owner

    This is annoying: I cannot reproduce the issue with HomeBrow. In a freshly installed HomeBrew installation on OSX 10.10.5:

    $ brew install python
    $ pip install pyobjc-core
    $ pip install pyobjc

    This results in a successful installation of PyObjC.

    @wooque: Do you have a different compiler installed with HomeBrew?

  8. wooque reporter

    Nope. If it means something this is the output of gcc, clang and cc versions.

    $ gcc -v
    Configured with: --prefix=/Applications/ --with-gxx-include-dir=/usr/include/c++/4.2.1
    Apple LLVM version 7.0.2 (clang-700.1.81)

    Also this is the list of things installed via Homebrew

    cmake           gettext         gmp             htop            libmagic        nettle          openssl         pyside          python3         ranger          shiboken        tcl-tk          wget            zsh

    Well I solved the problem by installing from source from tip. Problem is that version from PyPi - 3.1.1 doesn't have NSURLSessionStreamDelegate and NSProgressReporting in pyobjc / pyobjc-framework-Cocoa / Modules / _Foundation_protocols.m guarded with PyObjC_BUILD_RELEASE >=1011 but with >=1010, this is already fixed by commit fc965d3 dated 2016-03-31.

  10. David C

    I'm having the same problem as well. However I don't understand the fix. I'm a novice here. Per wooque's last comment, what exactly needs to be updated to get pyobjc to install correctly?

  11. wooque reporter

    Fix is to install from source. There are instruction on project overview, but if you don't have Mercurial installed (hg) you can download latest source from Downlaod/Tags/tip
