I can’t seem to start jupyter notebook from Mac terminal. I am
> using IJulia
> jupyterlab()
or
```julia
using IJulia
jupyter notebook()
```
```julia
When the browswer opnes and I select Julia for the kernel, I get this (I am pasting part of the error) error:

This seems to be the relevant line:

I’m guessing that you renamed or moved your Julia installation so that this path no longer works. Just re-run `build IJulia` at the package prompt in the Julia command line.

Sorry, I am just starting and not familiar with all the syntax; here is what I did but I got error:

First type `]` and only then when you get the `pkg>` prompt type `build IJulia`

Thanks; that fixed the issue; I can now start jupyterlab() successfully but still unable to run jupyter notebook(); is IJulia only for jupyterlab?

Normally, you should be able to run `jupyter notebook` in your terminal and have julia kernel as an option. Is julia among the options when you run `jupyter notebook` and click in New? Once I had a problem like this and I simply repeated `using Pkg; Pkg.add("IJulia")` steps and it worked for me.
You can see more about installation and running in this [link](https://nicedoc.io/JuliaLang/IJulia.jl).

As I wrote above, I can run jupyterlab with no error:
but I can not run jupyter notebook. When I try jupyter notebook, i get the following error:
```julia
julia> using IJulia
julia> jupyter notebook()
ERROR: syntax: extra token "notebook" after end of expression

Ahhhh, I see. The way that I run `jupyter notebook` is directly in the Terminal, not in the julia REPL. Try `exit()` and then run `jupyter notebook`.

At the Julia prompt, you run
```julia
using IJulia
notebook()
```
not `jupyter notebook` — the latter is shell syntax (e.g. for the terminal), not a Julia function.

i am now getting different error when I open the jupyter, see below
