Possible conflict of versions in requirements.txt? #4

Hi. Thanks for writing this software. I set it up years ago for a team and they love it. I was migrating the tool over to a new server (Windows 2019 Datacenter) and I couldn't get the first command we run after initial setup to execute. python manage recreate_db would always return an AttributeError can't set attribute coming from flask.

I ended up resolving it by updating versions of flask-sqlalchemy and sqlalchemy to latest versions than what are defined in the requirements.txt file.

Just wanted to put this out there if someone else runs into this issue.

Cheers

@rylincoln thanks for the report. Unfortunately I don't have access to a license server so its difficult for me to reproduce the issue. If your change passes the tests, ill gladly accept a PR.

Sure thing, - i'll work on running the tests and repot back once i get lmutil.exe talking to the license server (pretty sure this is an internal IT issue).

@rylincoln & @ishiland - I also experienced the "AttributeError can't set attribute" error described. This was on a Windows 2019 server and a License Manager at version 2020.0.

Updating the versions of flask-sqlalchemy and sqlalchemy to latest versions also resolved the issue for me.

I'm going to log another issue as I believe there have been changes to the structure of the FlexNet response that cause the app to improperly identify the License Server as being down.

With Flask-SQLAlchemy==2.4.1:

SQLAlchemy==1.4.41 fails with AttributeError can't set attribute

SQLAlchemy == 1.3.24 works

@geographic-technologies-group - I agree that the FlexNet response has likely changed. I made a PR with a slightly more flexible app.read_licenses.parse_server_info that may fix the issue for you.
