Solved Cannot install jupyter-lab

Hi, I'm trying to install Jupyter Lab in a 12.1 Jail by following this tutorial: https://project.altservice.com/issues/923

Everything goes smoothly until I do pip-3.7 install jupyter, where I get this error:

Code:
...

    ----------------------------------------

Does anyone know how to fix it?.
 
BTW, the file is in /usr/local/include, how can I tell the compiler to look there? maybe it is looking in /usr/include?

Fixed with this:

Code:
export C_INCLUDE_PATH=/usr/local/include/:${C_INCLUDE_PATH}
export CPLUS_INCLUDE_PATH=/usr/local/include/:${CPLUS_INCLUDE_PATH}

Hi,
I get:
Code:
schroter@SCHROTER:~ % sudo export C_INCLUDE_PATH=/usr/local/include/:${C_INCLUD
E_PATH}
C_INCLUDE_PATH: Undefined variable.
schroter@SCHROTER:~ % sudo export CPLUS_INCLUDE_PATH=/usr/local/include/:${CPLU
S_INCLUDE_PATH}
CPLUS_INCLUDE_PATH: Undefined variable.
Would anyone be able to help me in this regards.
Thanks & Best Regards

Hi, Could you please let me know how to use these lines. I get an error saying C_INCLUDE_PATH: Undefined variable. I am using tcsh shell
Thanks & Best Regards
