I don’t know if it will work for your case or not but what steps I take generally I am sharing with you

By Trying below I will try to fetch why this is not working.

   $ echo "Hello" > test.txt

   $ gpg --sign --default-key  test.txt

Error faced:

gpg: signing failed: No pinentry

gpg-agent[59045]: can't connect to the PIN entry module '/usr/local/bin/pinentry': IPC connect call failed

gpg-agent[59045]: failed to unprotect the secret key: No pinentry

From terminal I hit below cmd :

    cat ~/.gnupg/gpg-agent.conf

Check if below statement is present. Need to add if not present in gpg-agent.conf

pinentry-program /usr/local/MacGPG2/libexec/pinentry-mac.app/Contents/MacOS/pinentry-mac

Added pinentry path then run:

    $ gpgconf --kill gpg-agent

    $ gpg --sign --default-key  test.txt

Output:

gpg: using as default secret key for signing

Error: gpg failed to sign the data fatal
