# RecursionError when installing SageMath 8.2

I downloaded `sage-8.2-OSX_10.13.4-x86_64.dmg`

. Then I ran `./sage`

from the extracted `SageMath`

directory in a Terminal. Then I got the following error:

Last login: Sun Jun 10 23:17:18 on ttys001 /Users/jing/tools/SageMath/sage ; exit; ➜ ~ /Users/jing/tools/SageMath/sage ; exit; RecursionError: maximum recursion depth exceeded during compilation

It seems that you are attempting to run Sage from an unpacked source
tarball, but you have not compiled it yet (or maybe the build has not
finished). You should run `make`

in the Sage root directory first.
If you did not intend to build Sage from source, you should download
a binary tarball instead. Read README.txt for more information.

I am using macOS 10.13.4. Can anyone help me on this?
