5 years ago Ok, I managed to get it to run, it's a bit weird; this is still from cmd.exe:
C:\msys64\mingw64\bin>jupyter.exe
This version of C:\msys64\mingw64\bin\jupyter.exe is not compatible with the version of Windows you're running. Check your computer's system information and then contact the software publisher.
C:\msys64\mingw64\bin>jupyter-notebook.exe
failed to create process (C:\building\msys64\mingw64\bin\python3.exe "C:\msys64\mingw64\bin\jupyter-notebook-script.py").Then, I kind of started suspecting the path C:\building\msys64\mingw64\bin\python3.exe:
C:\msys64\mingw64\bin>C:\building\msys64\mingw64\bin\python3.exe
The system cannot find the path specified.

Use quit() or Ctrl-Z plus Return to exit
>>> ^ZOk, so it seems the path to python which has \building in it is wrong; let's try to run that "failed to create process" command with the right python path:

user@DESKTOP-PC MINGW64 /mingw64/bin
$ grep -r ....building...... jupyter*
jupyter-bundlerextension-script.py:#!C:/building/msys64/mingw64/bin/python3.exe

jupyter-serverextension-script.py:#!C:/building/msys64/mingw64/bin/python3.exeNot sure how to handle this ... Though, in https://github.com/msys2/MSYS2-packages/issues/1540 there is:
Strangely, I downloaded a PKGBUILD from https://github.com/Alexpux/MINGW-packages and built mingw-w64-x86_64-python3-notebook myself. It is able to start fine.
.... which I'd try, but I cannot find a directory containing the string "notebook" anywhere on that page ...
EDIT: Turns out, if I call jupyter-notebook.exe from MINGW64 shell, it also starts:
user@DESKTOP-PC MINGW64 ~
$ jupyter-notebook

...... but it doesn't really work, possibly because of this bug? Kernel not connected Python 3.7 · Issue #4444 · jupyter/notebook - here it is linked to mingw-w64-x86_64-python3-tornado 6.0.3-1, but apparently, to get it work, one needs a version 5 of tornado ....

Using msys2/mingw64 updated today, on a Windows 10 (64-bit) machine. I want to install Jupyter - so first, I tried to look at https://jupyter.org/install which says "Installing Jupyter with pip"; turns out Jupyter install via pip fails in MSYS2 shell:
... and it turns out, I cannot use
pipin MINGW64 ( python - Pip on MINGW64? - Stack Overflow )So, then I opened a MINGW64 shell, and tried to install the binary packages:
Fine - now I should test the start with
jupyter notebookbut:Just in case, I tried this in MINGW32 too:
The same error for MINGW32 also appears for MSYS2 shell too, which I guess is expected.
But I certainly did not expect
cannot execute binary file: Exec format errorwhen runningjupyter notebookin MINGW64.So, how can I run jupyter on MINGW64?
EDIT: just tried to run jupyter.exe in cmd.exe:
... and I got a popup window with:
... it is recognized as 16-bit application?!
