[PYTHON] Check! Troubleshooting when installing PyObjc on Mac

Hello, this is @dz_ this and Ohira Kazumi.

Prologue-Introduction

I've stumbled upon some of the PyObjc installations during the process, so I'll keep a reminder.

#Introduce PyObjc (update)
$ pip install -U pyobjc

Work environment

• Mac OS X El Capitan (10.11.5)
• python 2.7.12 (※)

• Initially, the system default python could not proceed due to the error described later, so we installed python other than the system default to support it. There is no particular reason, but I used the latest version of the 2 series. It was okay with 3 series.

trouble shooting

tool'xcodebuild' requires Xcode and error

error contents

The error is that xcodebuild is requesting Xcode itself, not the command line tools.

$ sudo pip install -U pyobjc

Please install Xcode from the Mac App Store.

Apparently, the version of pyobjc-core has 2.5.1 installed, but 3.1.1 is required.

pyobjc-core (2.5.1)

...<Abbreviation>...

I tried to update explicitly with sudo pip install -U pyobjc-core, but it was [Errno 1] Operation not permitted and could not be uploaded.

Therefore, I explicitly installed python other than the system default to deal with it. For version control of each language, ʻanyenv` is recommended. (Reference: Use phpenv with Check! Anyenv (Mac OS X))

#python version check
$ python --version
Python 2.7.10

#Check the version of pip
$ pip --version
pip 9.0.1 from /Library/Python/2.7/site-packages (python 2.7)

#Install pyenv using anyenv
$ anyenv install pyenv

#Reload the shell
$ exec $SHELL -l

# python 3.5.Install 2
$ pyenv install 2.7.12

#Check the installed version
$ pyenv versions
* system (set by /Users/user/.anyenv/envs/pyenv/version)
  2.7.12

# python 2.7.Enable 12
$ pyenv global 2.7.12

#pip update
$ pip install --upgrade pip

When I installed pyobjc-core in this state, it completed normally.

# pyobjc-core installation
$ pip install -U pyobjc-core
Collecting pyobjc-core

There is no problem if you install (update) pyobjc itself instead of pyobjc-core here.

Epilogue-Conclusion

Actually, it is a troubleshooting when trying to put pyBluez on Mac, but even if I clear the installation of PyObjc, the essential pyBluez has the following problem I couldn't install it ... It ended in the middle of my mind. (By the way, the pyBluez issue has been fixed and will appear in the release soon.)

• Mac PyBluez installation failure: pyobjc 3.1.1, OS X 10.11.5 #133
