Installation 在windows上安装带有OPAM的软件包失败

在windows上安装

OCaml

时，我遵循第一个步骤。我在执行时遇到以下错误：

opam install depext

# opam-version         1.3.0~dev (9fc27413c08030d909802dcdfb6e63b75d9dd762)
# os                   win32
# command              tar xfj /home/<user_name>/.opam/packages.dev/depext.1.0.5/opam-depext-full-1.0.5.tbz -C /cygdrive/c/Users/<user_name>/AppData/Local/Temp/opam-504-ccabea

运行命令：

tarxfj/home//.opam/packages.dev/depuxt.1.0.5/opam-depuxt-full-1.0.5.tbz

successfulls，并按预期提取文件

有人知道我如何继续安装吗

opam和ocal作为cygwin软件包提供。似乎您正在将Windows（而不是cygwin）与cygwin programsTry混合在一起，再次将其与

ocaml env exec--opam install depext混合在一起。您的环境（TMP？/TEMP？）看起来可疑。您是否遵循了这些说明？还有，这里有一些技巧
tar: /cygdrive/c/Users/<user_name>/AppData/Local/Temp/opam-504-ccabea: Cannot open: No such file or directory
tar: Error is not recoverable: exiting now
