To all R users
Good afternoon
Has anyone used the reticulate package with python3 within the MSYS2
(windows) environment ???
With the python2 version works without problems.
But my goal is to use PyGI (Gtk3) which is officially supported on
windows only by MSYS2.
Thanks in advance for any help!

You might have to add C:/msys64/mingw64/bin/ and/or another directory to the PATH environment variable to make it work. Use Dependency Walker [*] or a similar tool to find out which DLLs python37.dll depends on. Alternatively, use Sysinternals Process Monitor [**] to see which files does it try to open before a `reticulate` call fails. -- Best regards, Ivan [*] http://dependencywalker.com/ [**] https://docs.microsoft.com/en-us/sysinternals/downloads/procmon
Hello Ivan Krylov and all users, I think I understand your observation but there is no file named by python37.dll on the computer. It may be as static build inside python3.exe but if so should not give this error?
