Running `tox-current-env` tests with `--current-env` fails

When I run `tox-current-env` tests with `--current-env` then I see many tests to fail:

I found that when I do this:

Bắt đầu với tests/test_integration_tox4.py, đặc biệt là bài kiểm tra về môi trường tox native và cách xử lý TOX_WORK_DIR của nó. Tái hiện lần chạy --current-env và so sánh với lần chạy được báo cáo sau khi xóa TOX_WORK_DIR khỏi môi trường kiểm thử. Được xem là hoàn tất khi bộ kiểm thử tích hợp không còn báo các lỗi thiếu .tox/py39/bin/python và vượt qua số lượng kiểm thử đã nêu.
