[SalesForce] SFDX – No org configuration found for name

Ya, this is most likely from the CLI upgrade, and installing the plugin again probably won't help.

It might be because your alias contains .'s in it which I didn't think worked in v6 either. Can you try to update your alias and see if that resolves it?

sfdx force:alias:set newAliasWithoutDots=<yourscratchorg>
sfdx force:config:set defaultusername=newAliasWithoutDots

Update:

Do not plugins:install salesforcedx. This is a common mispractice and should not be done, since the CLI is bundled with salesforcedx already. It just takes up more space on your machine. The only time you would need to manually install salesforcedx is if you need to tie to a specific version or pre-release. i.e.

sfdx plugins:install salesforcedx@pre-release

DO NOT try to install pre-release right now as we are not in pre-release season.

That missing @oclif/config is a known issue when installing salesforcedx in v7 and will be patched.

You can't retrieve the contents of managed package classes via the API, but presumably, if you're trying to make an Unlocked Package, you simply forgot to specify the dependency:

{
  "packageDirectories": [
    {
      "path": "force-app",
      "package": "myPackageName",
      "versionName": "ver 0.1",
      "definitionFile": "config/features.json",
      "versionNumber": "0.1.0.NEXT",
      "default": true,
      "dependencies": [
        {
          "package": "docusign@X.Y.Z"
        }
      ]
    }
  ],
  "namespace": "",
  "sfdcLoginUrl": "https://login.salesforce.com",
  "sourceApiVersion": "47.0",
  "packageAliases": {
    "docusign@X.Y.Z": "04t..............."
  }
}

To get the 04t value, use:

sfdx force:package:installed:list

In the above JSON, replace X.Y.Z with the version number provided from the output of this install list.
