Tutorial Update Versi Python 2.7 ke Python 3 di OS X Yosemite

Berikut ini saya ingin menuliskan tutorial singkat bagaimana cara mengubah versi python dari 2.7 menjadi python versi 3.

1. Langkah pertama, unduhlah terlebih dahulu software python untuk OS X di https://www.python.org/downloads/ , kemudian pilihlah yang versi Mac.
2. Hapus direktori versi python yang ingin diupgrade. Misal python 2.7. Langkah-langkah adalah sebagai berikut:

localhost:~ bakulotek$ sudo rm -R /System/Library/Frameworks/Python.framework/Versions/2.7/
localhost:~ bakulotek$ sudo mv /Library/Frameworks/Python.framework/Versions/3.4/ /System/Library/Frameworks/Python.framework/Versions/
localhost:~ bakulotek$ sudo chown -R root:wheel /System/Library/Frameworks/Python.framework/Versions/3.4/
localhost:~ bakulotek$ sudo rm /System/Library/Frameworks/Python.framework/Versions/Current 
localhost:~ bakulotek$ sudo ln -s /System/Library/Frameworks/Python.framework/Versions/3.4/ /System/Library/Frameworks/Python.framework/Versions/Current
localhost:~ bakulotek$ sudo rm /usr/bin/pydoc
localhost:~ bakulotek$ sudo rm /usr/bin/python
localhost:~ bakulotek$ sudo rm /usr/bin/pythonw
localhost:~ bakulotek$ sudo rm /usr/bin/python-config
localhost:~ bakulotek$ sudo ln -s /System/Library/Frameworks/Python.framework/Versions/3.4/bin/pydoc3 /usr/bin/pydoc
localhost:~ bakulotek$ sudo ln -s /System/Library/Frameworks/Python.framework/Versions/3.4/bin/python3 /usr/bin/python
localhost:~ bakulotek$ sudo ln -s /System/Library/Frameworks/Python.framework/Versions/3.4/bin/pythonw3 /usr/bin/pythonw
localhost:~ bakulotek$ sudo ln -s /System/Library/Frameworks/Python.framework/Versions/3.4/bin/python3-config /usr/bin/python-config

Apabila langkah-langkah diatas sudah benar, maka jalankan python di terminal dengan mengetikkan "python" tanpa tanda petik. Hasilnya kurang lebih sebagai berikut :

localhost:~ bakulotek$ python
Python 3.4.2 (v3.4.2:ab2c023a9432, Oct  5 2014, 20:42:22) 
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
