Извините, я новичок во всем этом. Я не могу установить dlib внутри виртуальной среды pipenv, однако могу установить и импортировать ее вне виртуальной среды pipenv.
Когда я перехожу к папке, содержащей мой код, и набираю pipenv shell а затем python3 example.py код, который я хочу запустить, я получаю эту ошибку:
import dlib
ModuleNotFoundError: No module named 'dlib'
Затем я попытался установить dlib, используя следующие команды:
$ sudo apt-get update
$ sudo apt-get install build-essential cmake
$ sudo apt-get install libopenblas-dev liblapack-dev
$ sudo apt-get install libx11-dev libgtk-3-dev
$ sudo apt-get install python python-dev python-pip
$ sudo apt-get install python3 python3-dev python3-pip
$ pip3 install dlib
все работало хорошо, кроме последней команды, вот вывод, который я получаю, красным:
$ pip3 install dlib

Когда я попытался сделать то же самое за пределами виртуальной среды, все работало нормально.
Я из идей я очень ценю ваш совет.
Edit 1
Я попытался установить dlib в виртуальной среде pipenv с помощью conda, вот результат:

UnsatisfiableError: The following specifications were found
to be incompatible with the existing python installation in your environment:
Specifications:
- dlib -> python[version='2.7.*|3.5.*|>=3.5,<3.6.0a0']
- dlib -> python[version='>=2.7,<2.8.0a0']
Your python: python=3.7
If python is on the left-most side of the chain, that's the version you've asked for.
When python appears to the right, that indicates that the thing on the left is somehow
not available for the python version you are constrained to. Note that conda will not
change your python version to a different minor version unless you explicitly specify
that.
The following specifications were found to be incompatible with each other:
Package certifi conflicts for:
python=3.7 -> pip -> setuptools -> certifi[version='>=2016.09|>=2016.9.26']
dlib -> python=3.5 -> pip -> setuptools -> certifi[version='>=2016.09|>=2016.9.26']

Редактировать 2
Я убедился, что pipenv использует python 3.5 (как вы можете видеть в ошибке pip3 выше), но я все еще не могу установить dlib ни по pip3, ни по conda. И странно то, что ошибка conda говорит мне Your python: python=3.7, в то время как ошибка pip3 ясно говорит о том, что я использую python 3.5: Building extension for Python 3.5.9
Пожалуйста, советуйте.
