Question

Git一直在给我这个错误

    0 [main] sh (47116) C:\Users\Marcus\AppData\Local\GitHub\PortableGit_c7e0cbde92ba565cb218a521411d0e854079a28c\usr\bin\sh.exe: *** fatal error - cygheap base mismatch detected - 0x11C7400/0x1297400.
This problem is probably due to using incompatible versions of the cygwin DLL.
Search for cygwin1.dll using the Windows Start->Find/Search facility
and delete all but the most recent version.  The most recent version *should*
reside in x:\cygwin\bin, where 'x' is the drive on which you have
installed the cygwin distribution.  Rebooting is also suggested if you
are unable to find another cygwin DLL.

我尝试过的事情包括：

从C:\cygwin和C:\cygwin64删除cygwin并重新安装
使用卸载程序和安装程序重新安装github。
卸载github并手动删除其本地和漫游的appdata文件夹，然后重新安装。
重新启动计算机
重新定位C:\cygwin，它成功了，但没有解决任何问题。
重新定位%appdata%\Local\Github\PortableGit_c7e...\.它再次返回原始错误。

供参考，我正在运行Windows 10 64位。我能找到的唯一另一个问题就是针对我从未达成解决方案的错误：link here

我不确定除了完全重新安装Windows之外的其他地方，我们将非常感谢任何帮助。

Answer 1

来自git-for-windows（based on msys2）的shell不应在Cygwin中运行，也不应在msys2的不同安装中运行。

GitHub Desktop使用old git-for-windows (2.5.3, Sept. 2015)

对于git bash会话，您不需要Cygwin或GitHub Desktop。

解压缩latest git-for-windows azrchive you can find：

PortableGit-2.7.0-64-bit.7z.exe =＆gt; c:\prgs\git\PortableGit-2.7.0-64-bit

然后：

cd c:\prgs\git
mklink /J latest PortableGit-2.7.0-64-bit
set GIT_ROOT=c:\prgs\git\latest
set PATH=%PATH%;%GIT_ROOT%;%GIT_ROOT%\bin;%GIT_ROOT%\cmd;%GIT_ROOT%\us`\bin

然后，您将能够键入git-bash以启动基于Linux的bash会话。

或者，从常规CMD shell会话中，您将可以访问200多个unix命令（curl，cat，xargs，ls， ...）。
不需要Cygwin。

Answer 2

我有一个非常类似的问题，但既没有重启也没有重新安装git或cygwin帮助。我总是得到：

      1 [main] sh (12220) C:\Program Files\Git\usr\bin\sh.exe: *** fatal error - cygheap base mismatch detected - 0x37C7408/0x38E7408.

C:\Program Files\Git\mingw64/libexec/git-core\git-stash: fork: retry: Resource temporarily unavailable

我花了一段时间才弄清楚它是在我读到与“系统级强制ASLR”相关的Windows错误之后开始的，以及通过Windows UI提供的设置如何设置正确的注册表项。通过添加此注册表项使我的系统更安全后，cygwin forking破坏了：

Windows Registry Editor Version 5.00 
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\kernel]
"MitigationOptions"=hex:00,01,01,00,00,00,00,00,00,00,00,00,00,00,00,00

来源：Clarifying the behavior of mandatory ASLR

导致git-stash不再工作，cygwin工作（我后来安装）。删除该注册表项再次修复了该问题。

Answer 3

在系统的Windows Defender安全中心中禁用Force randomization for images (mandatory ASLR)。或exclude ASLR for git executables：

Get-Item -Path "C:\Program Files\Git\usr\bin\*.exe" | %{ Set-ProcessMitigation -Name $_.Name -Disable ForceRelocateImages }

Answer 4

重新启动为我修复了它。我可能因为升级Git for Windows而出现此错误。在做任何其他疯狂的事情之前尝试重新启动！

对我来说好了类似的错误ffmpeg $ ./configure ...

      1 [main] cmp (5984) C:\Program Files\Git\usr\bin\cmp.exe: *** fatal error - cygheap base mismatch detected - 0x180326400/0x180330400.

表示＆＃34;您正在尝试使用MSYS2进行构建，但意外地故障转移到某些git分布式cmp.exe文件，这些文件显然是不可用的＆＃34; （见VonC的回答）。

修复我的情况：将它们安装到MSYS2中：

$ pacman -S make

$ pacman -S diffutils # for cmp package

Answer 6

您安装的MSYS2中的某些软件包与x：\ cygwin \ bin冲突，因此只需在系统环境中删除MSYS2 PATH

Answer 7

在Windows 10上默认启用强制性ALSR之后。

我需要对所有git-bash可执行文件禁用ForceRelocateImages。为此，请创建一个小的PowerShell脚本或直接在PowerShell中键入以下代码。您需要以管理员身份运行PowerShell。

Get-Item -Path "C:\Program Files\Git\usr\bin\*.exe" | %{ Set-ProcessMitigation -Name $_.Name -Disable ForceRelocateImages }
Get-Item -Path "C:\Program Files\Git\bin\*.exe" | %{ Set-ProcessMitigation -Name $_.Name -Disable ForceRelocateImages }
Get-Item -Path "C:\Program Files\Git\*.exe" | %{ Set-ProcessMitigation -Name $_.Name -Disable ForceRelocateImages }

之后，git-bash可以正常工作。
