我试图在我的Python应用程序中利用MKL（英特尔数学内核库），该应用程序使用pipenv进行程序包管理和虚拟环境。
我已安装英特尔的Python发行版：
$ /opt/intel/intelpython3/bin/python --version
Python 3.6.5 :: Intel Corporation
现在我正尝试使用此Python发行版安装新的pipenv环境：
/home/.../test4 $ which pipenv
/home/.../.local/bin/pipenv
/home/.../test4 $ pipenv install --python=/opt/intel/intelpython3/bin/python

To activate this project's virtualenv, run pipenv shell.
Alternatively, run a command inside the virtualenv with pipenv run.
/home/.../test4 $ pipenv run python --version
Python 3.6.6
如您所见，此pipenv环境中的python版本不是用来创建带有pipenv参数的--python的版本。
应为Python 3.6.5 :: Intel Corporation，但应为Python 3.6.6。
Python 3.6.6是我的系统python3.6：
$ python3.6 --version
Python 3.6.6
$ which python3.6
/usr/bin/python3.6
所以问题是为什么pipenv的--python参数不会驱动将python可执行文件复制到虚拟环境中。如果那不是在虚拟环境中设置python可执行文件的方法，那是什么？
编辑：
生成的Pipfile：
$ vi Pipfile
[[source]]
url = "https://pypi.org/simple"
verify_ssl = true
name = "pypi"
[packages]
[dev-packages]
[requires]
python_version = "3.6"
