failure on macos

[moderakh]

Describe the bug

When I try to install this on macos it fails.

Did this error occur while using dotnet interactive?

• [x] .NET Jupyter Notebook

Screenshots

If applicable, add screenshots to help explain your problem.

the first command works fine:

dotnet tool install -g --add-source "https://dotnet.myget.org/F/dotnet-try/api/v3/index.json" Microsoft.dotnet-interactive

but the second one fails:

Please complete the following:

• OS
  • [x] macOS

I installed jupyter notebook and python using homebrew

[jonsequitur]

In that terminal do you have permission to write to the kernelspec location, e.g. one of the paths displayed by running jupyter kernelspec list?

[moderakh]

I do have permission yes, as that is a homebrew installation

jupyter kernelspec list
Available kernels:
  python3    /usr/local/share/jupyter/kernels/python3

however I tried this with sudo as well, that fails with the same message. Also one thing seems weird is System.ComponentModel.Win32Exception exception name. IMO this should be a platform independent failure. I don't have win32 on mac :-)

[moderakh]

any update on this?

[colombod]

Did you install python AND jupyter using brew? I have done both an Anaconda based setup and a pure python and pip install. All without issues. What are the access rights to the path /usr/local/share/jupyter/kernels/ ?

[moderakh]

I installed python3 and pip3 using homebrew. then I installed jupyter using pip3.

That path belong to current user.

ls -al /usr/local/share/jupyter/kernels/
total 0

[moderakh]

ping ... could you please provide an update?

[jbaron]

I installed Jupyter as a user (so not sudo pip global) and afterwards could successfully install .net interactive. The kernels are installed like this:

.net-csharp /Users/peter/Library/Jupyter/kernels/.net-csharp .net-fsharp /Users/peter/Library/Jupyter/kernels/.net-fsharp .net-powershell /Users/peter/Library/Jupyter/kernels/.net-powershell python3 /Users/peter/Library/Jupyter/kernels/python3

Perhaps something to try?

P.S What I also noticed is that after the recent updates of MacOs, it doesn't allow the /usr/local directory to be owned by a normal user (so even chown doesn't work anymore). I would guess if you tried sudo already this should not be the cause, but it is a recent change in the behaviour of MacOs that messes with many brew installations and the like.

[colombod]

@moderakh, we did improve the install logic, could you verify if the bug still is present?

[colombod]

@moderakh can we close this issue?

[moderakh]

I didn't try after your last comment. but I am not working on the relevant project for which I needed this (for the time being). feel free to close this. If I run into it again I will re-open or create a new one.

You are always welcome
