TAP tests not enabled in pg_dump

I want to execute some testing code but I conflict against error.
Please tell me how to fix it :)

Environment:
=================================================================
OSX: 10.14.6
postgresql: version 13 current development

In postgresql/src/bin/pg_dump dir I command below

$ make check PROVE_TESTS='t/001_basic.pi'

Error:
