我正在使用 Windows 版 Git（git 版本 2.5.3.windows.1），并且已将 vimdiff 设置为我的合并工具。git mergetool从 git bash 运行会导致以下错误：
E810: Cannot read or write temp files
E97: Cannot create diffs
Press ENTER or type command to continue
现在，我知道你在想什么，这是无法在 Windows 7 上运行 vimdiff-7-4，但我尝试了解决方案，但它不起作用（或者我遗漏了什么）。另外，我没有安装 vim，它是随 Windows 版 Git 一起提供的，我认为它可能有所不同（不是 100% 确定）。
这是我的~/.vimrc文件（在底部你会看到我添加了MyDiff()和set diffexpr=MyDiff()，也许我做错了？）（此外，值得一提的是，这个“顶部”不是来自 Windows 版 Git 的“示例”vimrc，而是来自 Cygwin 的，但我怀疑这并不重要。）：

我误解了它的用途MyDiff()，我以为它是为了在 Windows 上使用 vim一般来说，它是专门用于在 Windows 上的 cmd 中使用 vim 的——但我是通过 git bash 使用它的。解决方案是删除所有这些，如下所示这里运行这个：
MSYS_NO_PATHCONV=1 git mergetool
或者我可以设置MSYS_NO_PATHCONV=1在我的.bash_profile或.bashrc
# Set MSYS to not convert paths
export MSYS_NO_PATHCONV=1
