kernel doesn't show after installation

[eromoe]

env:

• windows10
• anaconda jupyterlab

> bitsadmin /transfer downloadCoursierCli https://git.io/coursier-cli "%cd%\coursier"
> bitsadmin /transfer downloadCoursierBat https://git.io/coursier-bat "%cd%\coursier.bat"
> .\coursier launch --fork almond -- --install

I restart jupyter after installation, but no new kernel show up .

jupyter kernelspec list:

Available kernels:

I'm hitting this issue as well.

NAME="Ubuntu"
VERSION="20.04.2 LTS (Focal Fossa)"

curl -Lo /usr/local/bin/coursier https://git.io/coursier-cli && \
    chmod +x /usr/local/bin/coursier && \
    /usr/local/bin/coursier launch --fork almond:0.10.9 --scala 2.12 -- --install && \
    rm -f /usr/local/bin/coursier

Or.. this helped:

# ./coursier launch --fork almond:0.10.9 --scala 2.12 -- --install --global

Actually, scala didn't work with just that. I also needed to do this shared cache stuff, else:

(base) jovyan@jupyter-server-v7-0:~$ java -jar /usr/local/share/jupyter/kernels/scala/launcher.jar --connection-file /home/jovyan/.local/share/jupyter/runtime/kernel-99aea8c3-a10b-4dd3-a7ff-5d0e5edfe0e9.json
Error: class almond.ScalaKernel not found

If it still doesn't work, try installing jdk-11.

apt-get install -y openjdk-11-jre-headless
