Resuelva el problema de pip3 correspondiente a python2 en mac (problema de apuntamiento de pip)

Resuelva el problema de pip3 correspondiente a python2 en mac (problema de apuntamiento de pip)

Lo mismo puede resolver el problema de pip correspondiente a Python3.

---

Uno, el problema

Verifique las versiones de pip y pip3 en mac, la versión de Python correspondiente a pip3 es 2.7

En circunstancias normales, debería ser: pip corresponde a Python2 y pip3 corresponde a Python3.

Dos, resolver

Use which para ver la ruta absoluta del comando pip.

~ » which pip                
/usr/local/bin/pip

El uso de easy_install para instalar pip en mac hará que tanto pip como pip3 se conviertan en pip

~ » sudo easy_install pip                 littlechieh6@bogon

O use el script get-pip.py en el sitio web bootstrap.pypa.io para instalar pip3, lo que hará que tanto pip como pip3 se conviertan en pip3

El punto clave de los scripts pip y pip3 originales es #!representar la ruta para ejecutar el script. Dado que tanto pip como pip3 son ejecutados por python3, use pip -Vypip3 -V

#!/Applications/Xcode.app/Contents/Developer/usr/bin/python3
# -*- coding: utf-8 -*-
import re
import sys
from pip._internal.cli.main import main
if __name__ == '__main__':
    sys.argv[0] = re.sub(r'(-script\.pyw|\.exe)?$', '', sys.argv[0])
    sys.exit(main())

Úselo vim /usr/local/bin/pippara apuntar al intérprete a Python2

#!/System/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7
# -*- coding: utf-8 -*-
import re
import sys
from pip._internal.cli.main import main
if __name__ == '__main__':
    sys.argv[0] = re.sub(r'(-script\.pyw|\.exe)?$', '', sys.argv[0])
    sys.exit(main())

Tres, el efecto
