IJulia status for v. 0.7/1.0 on Windows 10?

General Usage
21

Yes, I did. I redid it just to check:

julia> Conda.add("jupyterlab")
[ Info: Running `conda install -y jupyterlab` in root environment
Solving environment: done
…
The following packages will be UPDATED:

    jupyterlab: 0.34.3-py36_0 --> 0.34.7-py36_0
...

OK – this upgrades JupyterLab. To be on the safe side, I re-ran it, leading to:

julia> Conda.add("jupyterlab")
[ Info: Running `conda install -y jupyterlab` in root environment
Solving environment: done

# All requested packages already installed.

I then followed this with:

julia> jupyter = joinpath(Conda.BINDIR,"jupyter")
"C:\\Users\\user_name\\.julia\\packages\\Conda\\m7vem\\deps\\usr\\Library\\bin\\jupyter"

julia> run(`$jupyter lab`)
ERROR: IOError: could not spawn `'C:\Users\user_name\.julia\packages\Conda\m7vem\deps\usr\Library\bin\jupyter' lab`: no such file or directory (ENOENT)

Or: the alternative:

julia> jupyterlab = joinpath(Conda.BINDIR, "jupyter")*"-lab"
"C:\\Users\\user_name\\.julia\\packages\\Conda\\m7vem\\deps\\usr\\Library\\bin\\jupyter-lab"

julia> run(`$jupyterlab`)

What is inside that directory, i.e. what is

readdir("C:\\Users\\user_name\\.julia\\packages\\Conda\\m7vem\\deps\\usr\\Library\\bin\\")

?

There is nothing named jupyter* in that subdirectory.

If I climb up to .../Conda/m7vem/deps/usr/, there are some directories and files starting with jupyter under ...Conda/m7vem/deps/usr/pkgs/.

https://github.com/JuliaLang/IJulia.jl/issues/593 and https://github.com/JuliaLang/IJulia.jl/issues/363 seems related…

OK. Thanks – I’ll think over what to do. I may need to use a separate Python installation in a transitional period.
