Python issue with Mercurial

[susja]

'm using Windows 10 and have Cygwin and MobaXterm installed. I need to use Mercurial. It works fine from Cygwin but I want to run it from MobaXterm. I just installed Mercurial plugin for MobaXterm and it claimed that it should run with Python 2.7 In my case I have both Python 3 and Python 2. MobaXterm does not see Python 2. Here's my environment:
MobaXterm:
~/Desktop @ BOS-LTIRM181511
| => which hg
hg is aliased to `/bin/hg'
hg is /bin/hg
hg is /drives/c/MobaXterm/slash/bin/hg
✔
________________________________________________________________________________
| ~/Desktop @ BOS-LTIRM181511
| => which python
python is aliased to `ToolNotIncluded python'
✔
________________________________________________________________________________

python3 is /bin/python3

How could I fix it and make Mercurial run from MobaXterm?
P.S.
I created an alias to python and now from MobaXterm I could run: => python --version Python 2.7.15 But still I have the same error: => hg --version bash: /bin/hg: /bin/python: bad interpreter: No such file or directory Any help?
Thanks

It won't help you much but I wouldn't use a plugin that requires Python 2.7 to run. The plugin could be an abandonware. It will bring you a lot of troubles without benefits. There must be a way to use Mercurial for your project without passing through the outdated plugin.

I believe the new mercurial (5.7) is OK: https://www.mercurial-scm.org/

That was great hint. I was able to install Mercurial 5.7 and now I don't have an issue to run it from MobaXterm.
At the same time I hit another issue which I don't have using Cygwin i.e. authentication problem.
For some reason I can't access repository from MobaXterm but it works fine from Cygwin:
=> hg pull http://10.9.214.102/path1/path2
pulling from http://10.9.214.102/path1/path2
abort: http authorization required for http://10.9.214.102/path1/path2
I tried to add [auth] section to hgrc but it didn't help.
Any clue?

Thanks

try changing http to https

[susja]

Well ... change to https did not make a diff.
Not sure why it works fine on the same PC using Cygwin.
FYI: I am using Emacs as Cygwin package. When I use Emacs shell I also don't have problem to access the same repository.
Sounds like MobaXterm has some different user environment which is not recognized by Mercurial but valid for Cygwin.
Not sure ... what else to try

Thanks

I use Linux, haven't used a MS product for several years, so rusty.
Perhaps it's time to think of git?

Sure thing,
It's just for fun ..
Thanks for the help anyway
