If you find inspiration on stackoverflow, just go gitbash的安装目录Gitetc搜寻了一番，找到了如下文件：
bash.bashrc

There is such a line in it

# Set a default prompt of: user@host, MSYSTEM variable, and current_directory
# PS1='$$\e]0;\w\a$$\n$$\e[32m$$\u@\h $$\e[35m$$$MSYSTEM$$\e[0m$$ $$\e[33m$$\w$$\e[0m$$\n$ '

I removed the # in front of PS1 and then entered sh, and no error was reported
