Hasil yang diharapkan

Diharapkan tidak ada error logging saat hanya membuat virtualenv

Hasil sebenarnya

pembuatan virtualenv tampaknya berhasil, tetapi kesalahan yang tidak terduga muncul.

Langkah-langkah untuk mereplikasi

1. Jalankan pipenv --two untuk membuat virtualenv Python 2.7
2. Amati kesalahan
