无法运行安装后脚本

安装git后，我在一个对话框"unable to run post-install scripts“中看到以下内容。每次我打开git bash时，我都会在bash上看到以下内容：

mkdir: cannot create directory '/dev/shm': Read-only file system

Creating /dev/shm directory failed.
POSIX semaphores and POSIX shared memory will not work

mkdir: cannot create directory '/dev/mqueue': Read-only file system

‘可能的问题是什么？会不会给以后带来麻烦，尤其是在安装软件包的时候？

Answer 1

我也有同样的问题。解决方案是使用Run as Administrator选项打开Git Bash。

Answer 2

首先检查你的%PATH%。

如果您已经安装了latest Git for Windows，请打开一个CMD并设置一个简化路径，以查看在键入CMD会话“bash”时这些错误是否仍然存在：

首先键入：

set PATH=C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem
set GIT_HOME=C:\Path\to\Git
set PATH=%GIT_HOME%;%GIT_HOME%\bin;%GIT_HOME%\usr\bin;%GIT_HOME%\mingw64\bin;%PATH%

然后：

bash
