1.3.0 Build Fails with "Too Many Levels of Symbolic Links" Error

Jupyter NbClassic is a popular tool for creating and sharing interactive notebooks. However, users have reported issues with building the 1.3.0 version of the tool, resulting in a "Too many levels of symbolic links" error. In this article, we will delve into the details of this issue, explore the possible causes, and provide a step-by-step guide to troubleshoot and resolve the problem.

The "Too many levels of symbolic links" error occurs when the build process encounters a file path that contains too many symbolic links. This can happen when the file system is configured to use symbolic links, or when the build process is trying to access a file that is located in a directory with a long path.

To reproduce the issue, follow these steps:

  1. Run the command python -m build --wheel --no-isolation in the terminal.
  2. Observe the output, which should indicate that the build process has failed with the "Too many levels of symbolic links" error.

The expected behavior is that the build process should complete successfully, without encountering any errors.

The following information is relevant to the issue:

  • Operating System and version: Arch Linux
  • Browser and version:
  • Jupyter NbClassic version: 1.3.0

To troubleshoot the issue, run the command jupyter troubleshoot in the terminal and paste the output below:

Paste the output from running `jupyter troubleshoot` from the command line here.
You may want to sanitize the paths in the output.

To further troubleshoot the issue, run the command jupyter nbclassic with the --debug flag and paste the output below:

Paste the output from your command line running `jupyter nbclassic` here, use `--debug` if possible.

If the issue is related to the browser, paste the output from the JavaScript console below:

Paste the output from your browser Javascript console here, if applicable.

The "Too many levels of symbolic links" error can be caused by a variety of factors, including:

  • Symbolic links in the file system: If the file system is configured to use symbolic links, it can cause the build process to encounter too many levels of symbolic links.
  • Long file paths: If the file paths are too long, it can cause the build process to encounter too many levels of symbolic links.
  • Build process configuration: The build process configuration may be set to use symbolic links or long file paths, which can cause the error.

To resolve the issue, follow these steps:

  1. Check the file system configuration: Check if the file system is configured to use symbolic links. If it is, try to disable it or configure it to use a shorter path.
  2. Check the build process configuration: Check the build process configuration to see if it is set to use symbolic links or long file paths. If it is, to change it to use a shorter path or disable symbolic links.
  3. Run the build process with the --no-isolation flag: Run the build process with the --no-isolation flag to see if it resolves the issue.
  4. Try a different build process: Try a different build process, such as pip install or conda install, to see if it resolves the issue.

The "Too many levels of symbolic links" error can be a frustrating issue to resolve, but by following the steps outlined in this article, you should be able to troubleshoot and resolve the problem. Remember to check the file system configuration, build process configuration, and run the build process with the --no-isolation flag to resolve the issue.
Q&A: Resolving the "Too Many Levels of Symbolic Links" Error in Jupyter NbClassic

In our previous article, we explored the issue of the "Too many levels of symbolic links" error in Jupyter NbClassic and provided a step-by-step guide to troubleshoot and resolve the problem. In this article, we will answer some frequently asked questions (FAQs) related to this issue.

A: The "Too many levels of symbolic links" error can be caused by a variety of factors, including:

  • Symbolic links in the file system: If the file system is configured to use symbolic links, it can cause the build process to encounter too many levels of symbolic links.
  • Long file paths: If the file paths are too long, it can cause the build process to encounter too many levels of symbolic links.
  • Build process configuration: The build process configuration may be set to use symbolic links or long file paths, which can cause the error.

A: To check if the file system is configured to use symbolic links, follow these steps:

  1. Run the command ls -l in the terminal to list the files and directories in the current directory.
  2. Look for the ln -s command in the output, which indicates that the file system is configured to use symbolic links.

A: To disable symbolic links in the file system, follow these steps:

  1. Run the command sudo umount / to unmount the file system.
  2. Run the command sudo mount -o nofollow / to remount the file system without following symbolic links.
  3. Run the command sudo mount -o nofollow,ro / to remount the file system without following symbolic links and in read-only mode.

A: To check the build process configuration, follow these steps:

  1. Run the command pip show jupyter-nbclassic to list the installed packages and their versions.
  2. Look for the build command in the output, which indicates the build process configuration.

A: To change the build process configuration, follow these steps:

  1. Run the command pip install --upgrade jupyter-nbclassic to upgrade the package to the latest version.
  2. Run the command pip install --upgrade --force-reinstall jupyter-nbclassic to force the installation of the package with the latest configuration.

A: The --no-isolation flag is a command-line option that tells the build process to run without isolating the dependencies. To use the --no-isolation flag, follow these steps:

  1. Run the command python -m build --wheel --no-isolation to build the package without isolating the dependencies.

A: Some other troubleshooting steps you can take include:

  • Checking the file system for errors: Run the command fsck to check the file system for errors.
  • Checking the build process logs: Run the command pip show jupyter-nbclassic to list the installed packages and their versions, and look for the build command in the output.
  • Trying a different build process: Try a different build process, such as pip install or conda install, to see if it resolves the issue.

We hope this Q&A article has been helpful in resolving the "Too many levels of symbolic links" error in Jupyter NbClassic. Remember to check the file system configuration, build process configuration, and run the build process with the --no-isolation flag to resolve the issue.
