Hi @DeshengKong,

The first thing I would suggest to try is re-installing SCT v6.1.

If this does not fix the issue, then could you please upload the file install_sct_log.txt? You can find this file in this location: /Users/baobeibeixiaoshitou/sct_6.1/.

Kind regards,
Joshua

Given that you were able to successfully install SCT in this separate post, I will mark this post as resolved.
