Git running Meld as merge tool fails 'check_requirements import gi'

Question

Error while trying to merge conflicting files:

As version control I use git and I call Meld in order to merge conflicting files. (As IDE I use Qt creator, but I do not think it can be the problem). I do not understand why the merge procedure fails, because different times this procedure was used in order to merge the projects (the remote and the local one).

Answer 1

The gi module runs, except it fails to find the GTK DLL:

---------------------------
cx_Freeze: Python error in main script
---------------------------
Traceback (most recent call last):
  File "bin/meld", line 205, in check_requirements
    import gi
  File "C:/msys64/MINGW32/lib/python3.7/site-packages/gi/__init__.py", line 42, in <module>
  File "ExtensionLoader_gi__gi.py", line 23, in <module>
  File "ExtensionLoader_gi__gi.py", line 15, in __bootstrap__
  File "C:/msys64/MINGW32/lib/python3.7/imp.py", line 342, in load_dynamic
ImportError: DLL load failed: The specified module could not be found.

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

    raise Exception(error_text)

OK

I've added C:\Program Files (x86)\Meld\lib to my Path user environment variable, and now Meld works fine.
