Describe your environment

OS: Ubuntu
Python version: 3.11.6
Package version: 0.49b0

What happened?

The following commands (specifically opentelemetry-bootstrap --action install) fails during docker image build:

# Install OpenTelemetry tracing libraries and set up auto-instrumentation
RUN --mount=type=cache,target=/root/.cache,id=service_pip_cache_${TARGETPLATFORM} \
    python -m pip install opentelemetry-distro opentelemetry-exporter-otlp \
    && opentelemetry-bootstrap --action=install

Here are the logs:

Steps to Reproduce

I'm not able to reproduce this locally, but it happens regularly in our CI pipelines.

Expected Result

Actual Result

Failure

Additional context

No response

Would you like to implement a fix?

None

Although the issue seems to be caused by:

opentelemetry-instrumentation-test==1.0.0b.dev

the actual error originates from the sqlalchemy dependency (if included in your project):

opentelemetry-python-contrib/opentelemetry-instrumentation/src/opentelemetry/instrumentation/bootstrap_gen.py

Line 164 in 77613da

"library": "sqlalchemy",

; It appears to be the only module missing a version specifier (e.g., >= 3.0). Adding this version specifier resolves the issue on my end. Looks like something has changes in Python packaging module recently as I don't see any changes in bootstrap_gen.py.

@emdneto, please hold off on merging your PR and consider fixing this line first.

@rayrapetyan It's not just sqlalchemy, got the same error and I don't have sqlalchemy on my env.

Also the package is empty so am not sure why we even keep it around.

getting the same error

@emdneto
do we have a workaround for this while the fix is not deployed?
I could not find a flag to exclude libraries from opentelemetry-bootstrap

[nategoethel]

@Lelor downgrading the last release (0.48b0) has generally worked for us.

[rayrapetyan]

@rayrapetyan It's not just sqlalchemy, got the same error and I don't have sqlalchemy on my env.

I was wrong saying sqlalchemy should be in the list of dependencies of your project (seems it fails for everyone), but still the "packaging.version.InvalidVersion: Invalid version: '.'" error comes from the sqlalchemy version specifier absence and not the presence of "opentelemetry-instrumentation-test==1.0.0b.dev" (at least on my machine)

@rayrapetyan

We are in the process of resolving both issues separately, one to remove "opentelemetry-instrumentation-test==1.0.0b.dev" as a dependency and the other to add the version constraint to sqlalchemy, both of which will be released together in a patch soon. Ill update this issue once those are resolved.
