python — смерть ядра C ++ от Jupyter

У меня есть следующая трассировка, когда я запускаю ядро ​​c ++ 14 jupyter, используя cling. Я загрузил cling_2018-01-11_mac1012.tar.bz2 от

https://root.cern.ch/download/cling/

Затем добавил бин к пути. Для этого я открыл терминал и вошел

sudo nano /etc/paths

Вставил мой пароль, а затем, в нижней части файла, ввел путь к бинарной папке из загрузки (которую я получил, нажав команду i в файле, чтобы получить информацию), вышел и сохранил буфер. Протестируйте это с помощью

echo $PATH

Как только он был добавлен к пути, откройте новый терминал. Перейдите в загрузку, затем установите ядро ​​в:

/share/cling/Jupyter/kernel

pip install .

jupyter kernelspec install cling-cpp14

Затем я открыл блокнот со своего рабочего стола, открыл блокнот с ++ 14, но, к сожалению, ядро ​​умирает. Вот обратная связь. Любая помощь приветствуется.
