Was ist das richtige Format, um pip3 zu aktualisieren, wenn pip2 der Standard ist?
Ich entwickle für beidePython 2
und3.
Thus, ich muss beide @ verwendpip2
undpip3.
Beim Benutzenpip3 -
Ich erhalte diese Upgrade-Anfrage (letzte zwei Zeilen):
$ pip3 install arrow
Requirement already satisfied (use --upgrade to upgrade): arrow in c:\program files (x86)\python3.5.1\lib\site-packages
Requirement already satisfied (use --upgrade to upgrade): python-dateutil in c:\program files (x86)\python3.5.1\lib\site-packages (from arrow)
Requirement already satisfied (use --upgrade to upgrade): six>=1.5 in c:\program files (x86)\python3.5.1\lib\site-packages (from python-dateutil->arrow)
You are using pip version 7.1.2, however version 8.1.2 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.
Meine Standardeinstellungpip
ist fürPython 2,
nämlich:
$ python -m pip install --upgrade pip
Requirement already up-to-date: pip in /usr/lib/python2.7/site-packages
