Packages fail to be created, seemingly due to JSON decoding error

Actual Behavior

The build seems to succeed, but then there is a failure to create the package, with the error being something cryptic about JSON decoding.

It doesn't seem like any of these solved issues I found on Google (1)(2)(3) explain the error, but honestly I don't really understand how conda build works, so maybe they do.

For context I am trying to create conda packages for JupyterLab extensions for my organization to use. It works some of the time, but other times it doesn't, and the difference is unclear to me. If I should post examples of similar build scripts which do work, please let me know.

I will put the full output below at the end because it is extremely verbose.

Expected Behavior

The package creation should probably fail, but maybe give an error that is more informative to the technologically illiterate like myself.

Steps to Reproduce

In a directory (on Mac OS X) called plotly, have the following two files:

meta.yaml:

package:
  name: jupyterlab_plotly-extension
  version: "0.16.0"

source:
  git_url: https://github.com/jupyterlab/jupyter-renderers.git

requirements:
  build:
    - nodejs
    - jupyterlab>=0.33.4
  run:
    - nodejs
    - jupyterlab>=0.33.4

about:
  home: https://github.com/jupyterlab/jupyter-renderers/tree/master/packages/plotly-extension
  license: "BSD 3-Clause"
  license_file: LICENSE
  creator: "JupyterLab team"

build.sh

export PKG_NAME=jupyter-renderers
/bin/mkdir -p $CONDA_PREFIX/etc $CONDA_PREFIX/etc/$PKG_NAME
/bin/cp -a ./. $CONDA_PREFIX/etc/$PKG_NAME
cd $CONDA_PREFIX/etc
/bin/mkdir -p ./jupyter/nbdata ./conda/activate.d ./conda/deactivate.d
touch ./conda/activate.d/env_vars.sh ./conda/deactivate.d/env_vars.sh

##### Create activation script
echo "#\!/bin/bash" >> ./conda/activate.d/env_vars.sh
if [ ! -z "$JUPYTER_DATA_DIR" ]
then
    /bin/cp -a $JUPYTER_DATA_DIR/. $CONDA_PREFIX/etc/jupyter/nbdata
fi
echo "export JUPYTER_DATA_DIR=\$CONDA_PREFIX/etc/jupyter/nbdata" >> ./conda/activate.d/env_vars.sh
if [ ! -z "$JUPYTER_CONFIG_DIR" ]
then
    /bin/cp -a $JUPYTER_CONFIG_DIR/. $CONDA_PREFIX/etc/jupyter/nbconfig
fi
echo "export JUPYTER_CONFIG_DIR=\$CONDA_PREFIX/etc/jupyter/nbconfig" >> ./conda/activate.d/env_vars.sh

##### Create deactivation script
echo "#\!/bin/bash" >> ./conda/deactivate.d/env_vars.sh
echo "unset JUPYTER_DATA_DIR" >> ./conda/deactivate.d/env_vars.sh
echo "unset JUPYTER_CONFIG_DIR" >> ./conda/deactivate.d/env_vars.sh

##### Deactivate then reactivate conda environment so that changes take effect
export ENVIRONMENT_DIRECTORY=$CONDA_PREFIX
conda deactivate
source activate $ENVIRONMENT_DIRECTORY

# Actually install extension
cd $PKG_NAME/packages/plotly-extension
export NODE_OPTIONS=--max-old-space-size=4096
npm install
npm run build
jupyter labextension install .
cd ../../..
/bin/rm -rf ./$PKG_NAME
jupyter lab build

Then run cd ..; conda build plotly.

That usually means that your index got corrupted somehow. Most often, I need to go into the folder with the index files, and clean out the many .something.json files. I agree that we should handle it better.

To show that this isn't a one-off occurrence, I will also post here the meta YAML's, build scripts, and outputs for the other instances when this occurred for me.

@msarahan Sorry, I just saw your comment.

That usually means that your index got corrupted somehow. Most often, I need to go into the folder with the index files, and clean out the many .something.json files. I agree that we should handle it better.

Where is the folder with the index files?

I did conda build purge and conda clean -i but it did not change anything.

Thank you for taking the time to respond to this. I imagine it might be frustrating trying to answer the questions of someone who doesn't understand how conda build works.

generally <miniconda install root>/conda-bld/your-os

so ~/miniconda3/conda-bld/osx-64 for me

the most common reason this corruption happens is probably ctrl-c. I really need to handle that event better.

This is probably unnecessary information, my hope is just that there might be some commonalities in the meta YAML's and the build scripts which explain the source of the error.

@msarahan I am guessing that this wasn't the right thing to do, but anyway I went to $CONDA_PREFIX/conda-bld/osx-64 and deleted repodata.json and repodata.json.bz2.

Now the build fails, basically immediately, but the error is very similar, which does seem to confirm your suspicions (as far as I can tell, which is admittedly not much).

The problem persisted after doing conda build purge && conda clean -i again.

Yes, the files you need to delete are dotfiles. That's why I had .something.json earlier.

rm .*.json will do the trick.

@msarahan Oh, I didn't think to look for hidden JSON files. Removing the non-hidden JSON's (repodata.json) broke everything, so I uninstalled and reinstalled Conda. I will try to get around to re-testing these recipes later to see if the errors persist upon having updated the installation (and thereby most likely having removed the hidden JSON's).

Sorry for not reading your original post very carefully -- I could have saved myself a lot of time and trouble had I read it more carefully.

next time, you could just nuke the os folder, like conda-bld/osx-64. Conda-build will recreate it as necessary. Save any packages you want to keep before that, though.
