Hi everyone, I am trying to install dune using opam on Window 11. I come across this weird error

It seems like there is a weird path due to concatenating. Also, I look at the directory C:/Users/Minh/AppData/Local/Temp, but I cannot find the longcmd33326e file. Is there any way to solve this?
BTW, my opam version is 2.3.0 and my ocaml version is 5.3.0

There is an issue with the path passed to the shell (it was not quoted properly). This is probably related to some aspect of your particular setup rather than a Dune issue (see eg https://discuss.ocaml.org/t/dunelongcmd-linking-error-on-windows-using-ocamlopt/15469).

You may want to post your issue in https://discuss.ocaml.org/ or even https://github.com/ocaml/opam/issues instead.

Hi @nojb, thank you for your suggestions, I have posted this issue in https://discuss.ocaml.org/. I also looked at the discuss dunlongcmd Although it seems a similar error, the problem is that the dune in the discuss has been installed successfully, while this is not the case for me.
