GitHub Windows 7 sh.exe已停止工作

每次我从GitHub for Windows的命令行运行一个操作时，我都会看到一个弹出文件，说sh.exe已停止工作。用户界面似乎工作正常。命令行正在使用GIT附带的sh.exe。似乎无法找到任何表明为什么这不起作用的东西。我在git版本1.9.5.github.0上

where sh.exe
C:\Users\Joe\AppData\Local\GitHub\PortableGit_c2ba306e536fdf878271f7fe636a147ff37326ad\bin\sh.exe

您可以尝试运行：

ansicon -u sh.exe

如果这可以解决您的问题，我建议您尝试这样做：

Change the Rails command line / Git bash shortcuts to point to syswow64 instead of
system32 or vice-verse. If that doesn't work you can install/re-install 32-bit AND 64-bit
version of ansicon and then go from there.
