Requirements

This package has the same requirements as its dependencies:

• See Requirements from jupyter-server-proxy

• See Requirements from projector-installer

• If not already installed, install system packages required for JetBrains-in-a-browser support

  Example (ubuntu):

    # Install as root or superuser
    apt-get update && \
    DEBIAN_FRONTEND="noninteractive" apt-get install -y \
    libxtst6 \
    libxrender1 \
    libfontconfig1 \
    libxi6 \
    libgtk-3-0

• Install at least one of the supported Jetbrains IDEs. See installation examples below.

After installing the desired intelliJ product, make sure that:

• The idea.properties located at IDE_HOME/bin is writable by the user that has started jupyter/jupyterlab/jupyterhub. IDE_HOME is the location where you installed your desired jetbrains IDE
• The installed IDEs can be discovered by this package by using one of the following options:

  • Option 1: (Recommended)

    Create a link in the PATH that points to the installed jetbrains IDEs using the appropriate IDE name

    # Add a binary to the PATH that points to the IDE startup script.
    ln -s [IDE_HOME]/bin/[IDE].sh /usr/bin/[IDE]

  • Option 2

    Install the IDE in standard locations /opt/[IDE]. Use this option if you are not installing multiples editions of the same product. For example, if you are installing Pycharm community edition and Pycharm Professional, use the option 1. Same applies to IntelliJ idea editions.

Generic installation example:

    # Install IDEs as root or superuser
    mkdir -p /opt/[IDE]
    curl -L "https://download.jetbrains.com/product?code=[CODE]&latest&distribution=linux" \
    | tar -C /opt/[IDE] --strip-components 1 -xzvf -
    
    # Make The idea.properties editable by the user that has started jupyter/jupyterlab/jupyterhub
    chown <jupyter_launch_user> [IDE_HOME]/bin/idea.properties
   
    # Add a binary to the PATH that points to the IDE startup script.
    RUN ln -s /opt/[IDE]/bin/[IDE].sh /usr/bin/[IDE]

Make sure that you replace [IDE] with the name of the IDE in lowercase and provide its corresponding [CODE].

IntelliJ ultimate installation example:

    # As root or superuser
    # Install IntelliJ IDEA Ultimate
     mkdir -p /opt/idea
     curl -L "https://download.jetbrains.com/product?code=IU&latest&distribution=linux" \
    | tar -C /opt/idea --strip-components 1 -xzvf -
    
    # Make The idea.properties editable
    # If the user you use to start jupyter/jupyter lab/ jupyter hub is named tiaden
     chown tiaden /opt/idea/bin/idea.properties
    
    # Create a symbolic link in PATH that points to the Intellij startup script.
     ln -s /opt/idea/bin/idea.sh /usr/bin/intellij-idea-ultimate

Pycharm community edition example:

    # As root or superuser
    # Install Pycharm Community
     mkdir -p /opt/pycharm
     curl -L "https://download.jetbrains.com/product?code=PCC&latest&distribution=linux" \
    | tar -C /opt/pycharm --strip-components 1 -xzvf -
    
    # Make The idea.properties editable
    # If the user you use to start jupyter/jupyterlab/jupyter hub is named tiaden
     chown tiaden /opt/pycharm/bin/idea.properties
    
    # Create a symbolic link in PATH that points to the Intellij startup script.
     ln -s /opt/pycharm/bin/pycharm.sh /usr/bin/pycharm

Installation

PyPI

This repository can be installed directly from the Python Package Index.

python -m pip install jupyter-projector-proxy

If you want to use this integration with JupyterLab®, ensure that you have JupyterLab installed on your machine by running the following command:

python -m pip install jupyterlab

You should then install jupyterlab-server-proxy JupyterLab extension. To install the extension, use the following command:

jupyter labextension install @jupyterlab/server-proxy

Building From Sources

git clone https://github.com/tiaden/jupyter-projector-proxy.git

cd jupyter-projector-proxy

python -m pip install .

Usage

Upon successful installation of jupyter-projector-proxy, your Jupyter environment should present options to launch your installed IDE.

• Open your Jupyter environment by starting jupyter notebook or lab

  # For Jupyter Notebook
  jupyter notebook
  
  # For Jupyter Lab
  jupyter lab 

• If you are using Jupyter Notebook, on the New menu, select one of your installed IDEs . If you are using JupyterLab, select the installed IDE icon on the launcher.

Integration with JupyterHub

To use this integration with JupyterHub®, you must install the jupyter-projector-proxy Python package in the Jupyter environment launched by your JupyterHub platform.

For example, if your JupyterHub platform launches Docker containers, then install this package in the Docker image used to launch them.

Troubleshooting

In the environment that you have installed the package:

• Verify if the projector executable is discoverable (i.e. if it is in the PATH)

  $ which projector
   ~/.local/bin/projector

• Verify if the installed Jetbrains executable is discoverable (i.e. if it is in the PATH)

  $ which pycharm
   /usr/bin/pycharm

• Check if their Python version is 3.8 or higher

  $ python --version
  Python 3.8.10

• Verify that the user has Write permission on [IDE_HOME]/bin/idea.properties. If you don't see Permissions Granted after executing the below command, you need to follow the example above in order to modify the permissions of the user that runs jupyter/jupyterlab/jupyterhub

   # If you have installed pycharm like in the above example
  $ [ -w /opt/pycharm/bin/idea.properties ] && echo "Permissions Granted"

• Ensure that jupyter-projector-proxy and the jupyter executables are in the same environment as the python executable. For example if you are using VENV to manage your python environments:

  $ which python 
  /home/user/my-project/packages/.venv/bin/python
  
  $ which jupyter-projector-proxy
  /home/user/my-project/packages/.venv/bin/jupyter-projector-proxy
  
  $ which jupyter
  /home/user/my-project/packages/.venv/bin/jupyter

  Notice that jupyter-projector-proxy, jupyter and the python executable are in the same parent directory, in this case it is: /home/user/my-project/packages/.venv/bin

• Ensure that you are launching jupyter notebook using the same executable as listed above.

• Ensure that all two packages are installed in the same python environment

  # Pipe the output of pip freeze and grep for jupyter and jupyter-projector-proxy.
  # All two packages should be highlighted in the output.
  # If you don't see anyone of them, then either the packages missing in the output have been installed
  # in a different python environment or not installed at all.
  $ pip freeze | grep -E "jupyter|jupyter-projector-proxy"

• Ensure that all required system packages are installed for JetBrains-in-a-browser support

  Example (ubuntu):

  # Pipe the output of apt and grep for the required system packages.
  # All required packages should be highlighted in the output.
  # If you don't see anyone of them, then the packages missing in the output have not been installed
  $ apt list --installed | grep -E "libxtst6|libxrender1|libfontconfig1|libxi6|libgtk-3-0"

• If the integration is not showing up as an option to the dropdown box in the Jupyter notebook:

  #Run the following commands and verify that you are able to see similar output:
  
  $ jupyter serverextension list
  config dir: /home/user/anaconda3/etc/jupyter
      jupyter_server_proxy  enabled
      - Validating...
      jupyter_server_proxy  OK
      jupyterlab  enabled
      - Validating...
      jupyterlab 2.2.6 OK
  
  $ jupyter nbextension list
  Known nbextensions:
  config dir: /home/user/anaconda3/etc/jupyter/nbconfig
      notebook section
      jupyter-js-widgets/extension  enabled
      - Validating: OK
      tree section
      jupyter_server_proxy/tree  enabled
      - Validating: OK  $ pip freeze | grep -E "jupyter|jupyter-projector-proxy"
  
  # IF the server does not show up in the commands above, install:
  $ pip install jupyter_contrib_nbextensions
