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

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.

Cause analysis

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

Coping

#View a list of packages installed with pip
$ pip list

...<Abbreviation>...

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
  Using cached pyobjc-core-3.1.1.tar.gz
Installing collected packages: pyobjc-core
  Running setup.py install for pyobjc-core ... done
Successfully installed pyobjc-core-3.1.1

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.)
