Git difftool not opening sometimes

I have 2 folders (with different code) with git initialized. But when I do

git difftool -t meld 

one repo is working fine and asking me if I want to open files in meld to compare. The other one just output everything in the console and didn’t execute meld.

    You may have configured your diff.tool locally instead of globally (inspect the content of .git/config files in both your porjects, and your global ~/.gitconfig file).

    To set meld as your global difftool :

    git config --global diff.tool meld

    If in one repository you’re in conflicted state (check by git status), you need to use mergetool instead, e.g.

    git mergetool -t meld

    Related: git difftool runs git diff.

    Is it possible you have configured difftool, but not mergetool, and had a conflict outstanding?

    I found similar behaviour, when I had an existing conflict that needed resolving. I think what happened to me was that git was trying to be ‘helpful’ and launch mergetool when I asked for difftool. I had not set up any mergetool, only difftool. When I manually resolved the conflict with git add, difftool started working again. Very frustrating.
