SyntaxError: invalid syntax while installing

[11philip22]

Hi, When i try to install the package in my jupyter docker container using:

python3 -m pip install notebook zsh_jupyter_kernel
python3 -m zsh_jupyter_kernel.install --sys-prefix

I get this error:

Traceback (most recent call last):
  File "/usr/lib/python3.5/runpy.py", line 193, in _run_module_as_main
    "__main__", mod_spec)

Hey, @11philip22. Sorry for such a long time. You'll be able to solve the issue by installing a newer python in your Dockerfile before installing the kernels, at least version 3.7.
