TortoiseMerge 可以用作 Windows Git Bash 的 difftool 吗？

我刚刚开始使用 Git。我想使用 TortoiseMerge 作为 difftool 和 mergetool。

In my $HOME/.gitconfig我有以下部分。我已经删除了这个问题的用户和颜色部分。

[merge]
    tool = tortoisemerge
[mergetool "tortoisemerge"]
    cmd = \"TortoiseMerge.exe\" -base:\"$BASE\" -mine:\"$LOCAL\" -theirs:\"$REMOTE\" -merged:\"$MERGED\"
[diff]
    tool = tortoisemerge
[difftool "tortoisemerge"]
    cmd = \"TortoiseMerge.exe\" -base:\"$BASE\" -mine:\"$LOCAL\" -theirs:\"$REMOTE\" -merged:\"$MERGED\"

如果我在 Git Bash 提示符下输入 tortoisemerge，它就会加载。已知它在路上。但如果我输入命令，则会出现以下错误。

Rich:mygittest (master *)
$ git difftool
error: 'tortoisemerge' can only be used to resolve merges
merge tool candidates: kompare emerge vimdiff
No known merge resolution program available.
external diff died, stopping at readme.txt.
Rich:mygittest (master *)
$ 

我不明白什么才能让这项工作成功？ Tortoisemerge 与 TortoiseSVN 一起安装。

以下设置对我来说效果很好。但是，我使用的是 TortoiseGit，而不是 TortoiseSVN。请注意 diff 参数的差异。

[diff]
  tool = tortoisediff
[difftool]
  prompt = false
[merge]
  tool = tortoisemerge
[mergetool]
  prompt = false
  keepBackup = false
[difftool "tortoisediff"]
  cmd = \""c:/Program Files/TortoiseGIT/bin/TortoiseGitMerge.exe"\" -mine "$REMOTE" -base "$LOCAL"
[mergetool "tortoisemerge"]
  cmd = \""c:/Program Files/TortoiseGIT/bin/TortoiseGitMerge.exe"\" -base "$BASE" -theirs "$REMOTE" -mine "$LOCAL" -merged "$MERGED"
