Cannot enable helium package

[ro...@orange.com]

Hello,

I wish to integrate VEGA visualizations on zeppelin (version : 0.8.2) . So I created 3 files to import these visualizations on Helium :


-        HelloWorld.js : /home/romain/visu-vegas/Test01_HelloWorld/HelloWorld.js

-        HelloWorld.json : /home/romain/visu-vegas/Test01_HelloWorld/HelloWorld.json

-        package.json : /home/romain/visu-vegas/Test01_HelloWorld/package.json


This is my package.json :

{
    "name": "HelloWorld",
    "description": "affichage d'une phrase",
    "version": "1.0.0",
    "main": "HelloWorld",
    "author": "",
    "license": "Apache-2.0",
    "dependencies": {
        "zeppelin-tabledata": "*",
        "zeppelin-vis": "*",
        "vega": "^5.16.1",
        "vega-embed": "^6.12.2",
        "vega-lite": "^4.16.7"
    }
}

When I click on "enable" for import "HelloWorld" visualizations, it returns me an error whereas when I do the manipulation in command line (putty) there is no error. Below is a copy of the error.

com.github.eirslett.maven.plugins.frontend.lib.TaskRunnerException: 'yarn install --fetch-retries=2 --fetch-retry-factor=1 --fetch-retry-mintimeout=5000 --registry=http://registry.npmjs.org/' failed. (error code 1)

To see the logs, I run a command line: "tail -f zeppelin-romain-vmlinux.log" from this directory: cd zeppelin-0.8.2-bin-all/logs.
So, here are the corresponding error logs when I click on "enable":

ERROR [2020-10-01 12:19:12,970] ({qtp1580893732-16} HeliumRestApi.java[enablePackage]:216) - com.github.eirslett.maven.plugins.frontend.lib.TaskRunnerException: 'yarn install --fetch-retries=2 --fetch-retry-factor=1 --fetch-retry-mintimeout=5000 --registry=http://registry.npmjs.org/' failed. (error code 1)
java.io.IOException: com.github.eirslett.maven.plugins.frontend.lib.TaskRunnerException: 'yarn install --fetch-retries=2 --fetch-retry-factor=1 --fetch-retry-mintimeout=5000 --registry=http://registry.npmjs.org/' failed. (error code 1)

But this command goes to CLI when I'm in the bundle directory.

Do you have any idea why it doesn't work?

Thank you.
Sincerely.

Romain D.
