Contributing: Unable to build the project

[pramod-io]

I tried to follow the instructions in the Contributing page to build the project.

When I attempt to run yarn build, I get the following error.

    ✖  @jupyter-notebook/lab-extension:build
$ jlpm run build:labextension:dev
       Internal Error: @jupyter-notebook/root@workspace:.: This package doesn't seem to be present in your lockfile; run "yarn install" to update the lockfile

I tried running yarn install yarn install --refresh-lockfile after reading the error message, but ran into the same error when I ran yarn build again.

My node version is v23.1.0, and yarn version is 1.22.22.

Please let me know if I'm doing anything wrong. Cheers!

I tried running yarn install yarn install --refresh-lockfile after reading the error message, but ran into the same error when I ran yarn build again.

The contributing page mentions using jlpm for installing dependencies and running the build scripts. Did you try to do that? You may want to remove your local node_modules folder just in case.

Thank you! I used jlpm instead of yarn and I was able to build the project.
