Ungayitshintsha njani i-python 3 kunye ne-python 2 kwi-Linux

Kuxhomekeka kwisicelo esenziwe kwiPython oqhubayo, inokudibana netoliki ye-python 3, python 2 okanye zombini. Ngamanye amaxesha sine-python 3 kunye ne-python 2 efakiweyo, kodwa nokuba sixelela isixhobo esingakanani ukuba sibaleke nge-python 2, iyaqhubeka nokusebenza nge-python 3, ke esona sisombululo silula kule ngxaki buyisela python 3 nge python 2.

Kubalulekile ukuba uqaphele ukuba isisombululo endicebisa ukubuyisela i-python 3 nge-python 2, ichaphazela zonke iinkqubo ezisebenza nge-python, ke ezinye zezicelo zakho azinakho ukuqhuba.

Guqula python 3 kunye python 2

Ukutshintsha i-python 3 nge-python 2 kufuneka silandele la manyathelo alandelayo:

• Faka i-python 2 ngesudo

• Guqula i-symlink eyenziwe yipython 3 ibe /usr/bin/python ngo python 2

cd /usr/bin
ls -l python
    lrwxrwxrwx 1 root root 7  17 Dec. 12:04 python -> python3
ln -sf python2 python
ls -l python
    lrwxrwxrwx 1 root root 10 Apr 11 14:28 python -> python2

• Guqula ikhonkco lokomfuziselo elenziwe yiphakheji virtualenv en /usr/bin/virtualenv

cd /usr/bin
ln -sf virtualenv2 virtualenv

Ngala manyathelo alula uya kuba ne-python 2 njengetoliki emiselweyo, ngendlela efanayo, ungaqinisekisa ukuba le yimeko yomyalelo olandelayo:

python --version
