Error on starting Jupyter Lab: "Unable to find server plugin version, consider upgrading."
See original GitHub issueChecklist prior to opening an issue
- I have followed fully the installation steps laid out in the documentation site.
- I have restarted jupyterlab.
- I have read the FAQ section in the documentation site.
Describe the bug
I know that issue #111 is basically the same, however, I have repeated all the same steps and I’m still getting the same error and I’m not able to format my code. Another difference I noticed is that when I print out both extension lists, the first line says Config option 'kernel_spec_manager_class' not recognized by 'ListLabExtensionsApp'
. I’m not sure if this has anything to do with it or not.
Diagnostic commands Please attach the output of the following commands (please format them properly)

Holy moly, sorry about that, you are right, the
jupyterlab_code_formatter
was not in theenvironment.yml
. Thank you very much!Hey @ryantam626 , thanks for the reply.
Should
@ryantam626/jupyterlab_code_formatter v1.3.6 enabled OK
mean that the plugin is installed?
