I was installing Mysys2 then a textbox popped up. I did some research and realize I didn't have cygwin on my computer. So I installed cygwin. But that did not fix anything.

Textbox popped up while installing Mysys2

I also try to run that code in bash then an error appeared:

    0 [main] bash (19644) C:\cygwin64\bin\bash.exe: *** fatal error - cygheap base mismatch detected - 0x1156408/0x1106408.
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.

But I did install cygwin and there is cygwin1.dll in C:\cygwin64\bin

How do I solve this problem?

    What do you mean? That is not my question! You should help me solve my problem instead of showing some similar questions. Those similar questions do not help! – Black Jack MC Feb 05 '22 at 14:18
  • You do not need to have cygwin installed to install or run msys2. It is possible that you have too much stuff in your path. Cygwin should not be in your path except when running a cygwin shell. You may have different versions of bash interfering with each other. Git bash for example, should not be in your path. Use `where bash` in cmd or `which -a bash` in bash as required to find duplicates. – Doug Henderson Feb 05 '22 at 20:23
  • @BlackJackMC MSYS2 is not using `cygwin1.dll`; the error message is misleading as their library is called `msys-2.0.dll`. I agree with Doug that you need to clean a bit your PATH as probably you have multiple version of the MSYS2 enviroment – matzeri Feb 06 '22 at 15:47
