Unable to install django-heroku on mac osx Mojave

[German91]

When I try to install django-heroku in my project I have this error:

An error occurred while installing psycopg2==2.8.3 --hash=sha256:128d0fa910ada0157bba1cb74a9c5f92bb8a1dca77cf91a31eb274d1f889e001 --hash=sha256:227fd46cf9b7255f07687e5bde454d7d67ae39ca77e170097cdef8ebfc30c323 --hash=sha256:2315e7f104681d498ccf6fd70b0dba5bce65d60ac92171492bfe228e21dcc242 --hash=sha256:4b5417dcd2999db0f5a891d54717cfaee33acc64f4772c4bc574d4ff95ed9d80 --hash=sha256:640113ddc943522aaf71294e3f2d24013b0edd659b7820621492c9ebd3a2fb0b --hash=sha256:897a6e838319b4bf648a574afb6cabcb17d0488f8c7195100d48d872419f4457 --hash=sha256:8dceca81409898c870e011c71179454962dec152a1a6b86a347f4be74b16d864 --hash=sha256:b1b8e41da09a0c3ef0b3d4bb72da0dde2abebe583c1e8462973233fd5ad0235f --hash=sha256:cb407fccc12fc29dc331f2b934913405fa49b9b75af4f3a72d0f50f57ad2ca23 --hash=sha256:d3a27550a8185e53b244ad7e79e307594b92fede8617d80200a8cce1fba2c60f --hash=sha256:f0e6b697a975d9d3ccd04135316c947dd82d841067c7800ccf622a8717e98df1! Will try again.

I'm using pipenv, I tried to install psycopg locally using brew and also I tried with two different macs but I can't make it work.
