pip newer version available

[Csaba Raduly]

Hi all,

I recently installed python27-pip (20.2.2-1) and did a "pip install
grip", and at the end, pip displayed the following warning (or maybe
it's just an advertisement)

WARNING: You are using pip version 20.1.1; however, version 20.2.4 is available.
You should consider upgrading via the
'c:\users\csaba\appdata\local\programs\python\python38\python.exe -m
pip install --upgrade pip
' command.

Is it a good idea doing this upgrade ("behind the back" of the Cygwin
installer), or should I ignore this message until pip 20.2.4 (or
higher) becomes available as a Cygwin package?

Also, why is there a discrepancy between Cygwin's pip version and
pip's own version?

$ which python
/usr/bin/python
$ python -V
Python 2.7.18
$ which pip
/cygdrive/c/Users/Csaba/AppData/Local/Programs/Python/Python38/Scripts/pip

Whoops!

$ which grip
/cygdrive/c/Users/Csaba/AppData/Local/Programs/Python/Python38/Scripts/grip

$ find /usr -name pip -type f
$

Check https://cygwin.com/cgi-bin2/package-cat.cgi?file=x86_64%2Fpython27-pip%2Fpython27-pip-20.2.2-1&grep=%5Cbpip%5Cb

$ which pip2
/usr/bin/pip2

Aha!

$ pip2 install grip
... lots of output ...
WARNING: You are using pip version 20.2.2; however, version 20.2.4 is available.
You should consider upgrading via the '/usr/bin/python2.7 -m pip
install --upgrade pip' command.

$ which grip
/usr/bin/grip

Finally, sanity returns. Still, the question remains whether upgrading
pip like this is advisable or not.
