Missing azure storage or identity packages.

Error message

Missing azure storage or identity packages.

What it means

Raised by upload_command in jitrollingbuild.py inside a bare try/except wrapping `from azure.storage.blob import ...` and `from azure.identity import AzureCliCredential`. If either import fails, the except block logs install hints and raises this error. Upload requires the Azure SDK packages to authenticate and write blobs.

Solutions

1. Install both packages: `pip install azure-storage-blob azure-identity`.
2. Confirm you are installing into the same interpreter that runs the script (`python -m pip install ...` or `py -3 -m pip install ...` on Windows).
3. Activate the correct virtualenv before re-running upload.

Example fix

// before
python jitrollingbuild.py upload -git_hash abc   # 'Missing azure storage or identity packages.'
// after
python -m pip install azure-storage-blob azure-identity
python jitrollingbuild.py upload -git_hash abc

import importlib.util
for mod in ("azure.storage.blob", "azure.identity"):
    if importlib.util.find_spec(mod) is None:
        raise SystemExit(f"Missing {mod}; run: pip install azure-storage-blob azure-identity")

When it happens

Trigger: Running `jitrollingbuild.py upload` in a Python environment that lacks azure-storage-blob or azure-identity, or where they are installed in a different interpreter than the one running the script.

Common situations: Fresh checkout without pip-installing dependencies; using the system python3 while packages were pip-installed for a venv; CI image missing the Azure SDK.
