RuntimeError: JupyterLab failed to build

I'm working to troubleshoot the installation of an extension in Jupyter lab (https://github.com/krassowski/jupyterlab-lsp). I'm using MacOS 11.4. Following extension installation, a rebuild is required. I used

jupyter lab build

and

jupyter lab build --minimize=FALSE

(to potentially address any memory issues), however the rebuild fails with the following message:

An error occured.
RuntimeError: JupyterLab failed to build
See the log file for details:  /var/folders/hm/dsc1zn0j30s31yp_n6911dym0000gn/T/jupyterlab-debug-v9tx8kpz.log

Based on similar issues, I believe there is a memory issue that needs to be addressed. That said, I cannot identify the location of the log file to troubleshoot further. The file does not show up in a spotlight search, nor do any of the directories listed.

As the author of this extension I do not recommend installing it from source (or installing any other JupyterLab extension which is also distributed as a prebuilt extension from source, see this answer for details). Instead please use JupyterLab 3.0+ and install the prebuilt version using pip or conda (which does not require the build step) as demonstrated in the README.

Please uninstall the source extension:

jupyter labextension uninstall @krassowski/jupyterlab-lsp

Ensure it is gone by checking:

jupyter labextension list

Update JupyterLab:

pip install -U jupyterlab>=3
# or if using conda:
# conda install -c conda-forge jupyterlab>=3

And then install the extension:

pip install jupyterlab-lsp
# or if using conda:
# conda install -c conda-forge jupyterlab-lsp

And follow with installation of language servers as needed and explained in the README. In case of any problems please let me know.
