It complains C:\Users\alkorang\.julia\packages\WinRPM\Zs9v\cache\2\mingw64-gcc-c%2B%2B-7.2.0-3.2.noarch.cpio does not exist.

In C:\Users\alkorang\.julia\packages\WinRPM\Zs9v\cache\2\, there is mingw64-gcc-c++-7.2.0-3.2.noarch.cpio instead of mingw64-gcc-c%2B%2B-7.2.0-3.2.noarch.cpio. So I changed the file name manually but got the same error.
