Im trying to install the WebIO labextension to use in Jupyter Lab. I had read that I must build the WebIO in the Julia REPL, but the log of the build says

I have installed node 10.13.0.
I checked that the labextension was not installed with the command jupyter labextension list, however it seems installed for the classical jupyter notebook because it appears with an “ok” in the list provided by the command jupyter nbextension list.
