 ╰─ $ cr version
Crystal 1.6.0-dev [43f0a6455] (2022-10-04)

LLVM: 14.0.6
Default target: x86_64-pc-linux-gnu

The really wired things is, the same issue happen on 1.5.1 if i set CRYLSTAL_PATH like this:

export CRYSTAL_PATH=~/Dropbox/common/crystal/lib/empty_folder:$(crystal env CRYSTAL_PATH)

even, ~/Dropbox/common/crystal/lib/empty_folder is just a empty folder

I consider this issue probably relative to https://github.com/crystal-lang/crystal/issues/12529
