Question

I’m sure it is not a permissions issue cause it actually can create some directories.

Example:

FileUtils.mkdir "/tmp/foo"

works well

but

FileUtils.mkdir "/tmp/bar/foo"

fails with error

Errno::ENOENT: No such file or directory - /tmp/bar/foo

which does ot make sense to me cause i know it does not exists and that’s why i want to create it.

Answer 1

you need FileUtils.mkdir_p "/tmp/bar/foo"

mkdir_p behaves exactly as mkdir -p on UNIXes – if some dir does not exists it will be created.

I bet there are no /tmp/bar dir and Ruby fails to create a dir into an non-existing folder.
