but get an error after jupyter lab buildinstruction.
the error is:
[LabBuildApp] JupyterLab 3.0.7
[LabBuildApp] Building in /Users/jacques/opt/anaconda3/envs/jlb/share/jupyter/lab
[LabBuildApp] Building jupyterlab assets (production, minimized)
Build failed.
Troubleshooting: If the build failed due to an out-of-memory error, you
may be able to fix it by disabling the `dev_build` and/or `minimize` options.
If you are building via the `jupyter lab build` command, you can disable
these options like so:
jupyter lab build --dev-build=False --minimize=False
You can also disable these options for all JupyterLab builds by adding these
lines to a Jupyter config file named `jupyter_config.py`:
c.LabBuildApp.minimize = False
c.LabBuildApp.dev_build = False
If you don't already have a `jupyter_config.py` file, you can create one by
adding a blank file of that name to any of the Jupyter config directories.
The config directories can be listed by running:
jupyter --paths
Explanation:
- `dev-build`: This option controls whether a `dev` or a more streamlined
`production` build is used. This option will default to `False` (i.e., the
`production` build) for most users. However, if you have any labextensions
installed from local files, this option will instead default to `True`.
Explicitly setting `dev-build` to `False` will ensure that the `production`
build is used in all circumstances.
- `minimize`: This option controls whether your JS bundle is minified
during the Webpack build, which helps to improve JupyterLab's overall
performance. However, the minifier plugin used by Webpack is very memory
intensive, so turning it off may help the build finish successfully in
low-memory environments.
An error occured.
